Subject: intel-iommu: Fix section mismatch dmar_ir_support() uses dmar_tbl.

dmar_tbl is declared as __initdata, but dmar_ir_support() is not declared
as an __init function.  Fix is simple since the only caller of dmar_ir_support
(intr_remapping_supported) is an __init function.

Subject: ACPI: delete the "acpi=ht" boot option

acpi=ht was important in 2003 -- before ACPI was
universally deployed and enabled by default in
the major Linux distributions.

At that time, there were a fair number of people who
or chose to, or needed to, run with acpi=off,
yet also wanted access to Hyper-threading.

Today we find that many invocations of "acpi=ht"
are accidental, and thus is it possible that it
is doing more harm than good.

In 2.6.34, we warn on invocation of acpi=ht.
In 2.6.35, we delete the boot option.

Subject: mmc: msm_sdcc: Clean up clock management and add a 10us delay after
 enabling clocks

It appears that in some cases there may be a delay on the ARM9 in enabling our clock.
As a result, we may put the controller into a bad state. Delay 10us after enabling
clocks to let the peripheral settle. Note - this is all imperical.

Also ensure set_ios() callback grabs the host lock.

Subject: msm: Add 'execute' datamover callback

Based on a patch from Brent DeGraaf:

"The datamover supports channels which can be shared amongst devices.
As a result, the actual data transfer may occur some time after the
request is queued up. Some devices such as mmc host controllers
will timeout if a command is issued too far in advance of the actual
transfer, so if dma to other devices on the same channel is already
in progress or queued up, the added delay can cause pending transfers
to fail before they start. This change extends the api to allow a
user callback to be invoked just before the actual transfer takes
place, thus allowing actions directly associated with the dma
transfer, such as device commands, to be invoked with precise timing.
Without this mechanism, there is no way for a driver to realize
this timing. Also adds a user pointer to the command structure for use
by the caller to reference information that may be needed by the
callback routine for proper identification and processing associated
with that specific request. This change is necessary to fix problems
associated with excessive command timeouts and race conditions in the
mmc driver."

This patch also fixes all the callers of msm_dmov_enqueue_cmd() to
ensure their callback function is NULL.

From 8b1c2ba274c8416afb7eab3bd788f98a917efe06 Mon Sep 17 00:00:00 2001
From: San Mehat <san@google.com>
Date: Mon, 16 Nov 2009 10:17:30 -0800
Subject: mmc: msm_sdcc: Wrap readl/writel calls with appropriate clk delays

As it turns out, all sdcc register writes must be delayed by at
least 3 core clock cycles for the writes to take effect. *sigh*

    Also removes the 30us constant delay on clock enable in favor
of a 3 core clock delay.

From 56a8b5b8ae81bd766e527a0e5274a087c3c1109d Mon Sep 17 00:00:00 2001

Subject: mmc: msm_sdcc: Reduce command timeouts and improve reliability.

Based on an original patch by Brent DeGraaf:

"Previous versions of the SD driver were beset with excessive command
timeouts. These timeouts were silent by default, but happened
frequently, especially during heavy system activity and concurrent
access of two or more SD devices. Worst case, these timeouts would
occasionally hit at the end of a successful write, resulting in false
failures that could adversely affect journaling file systems if timing
was unfortunate. This update tightens the association and timing between
dma transfers and the commands that trigger them by utilizing a new api
implemented in the datamover.  In addition, it also fixes a dma cache
coherency issue that was exposed during testing of this fix that
occasionally resulted in card corruption.  Processing of results in the
interrupt status routine was modified to process command results prior to
data because overwritten command results were observed during testing
since the data section can result in command issuances of its own.
This change also eliminates the software command timeout, relying entirely
on the hardware version, since the software timeout was found to cause
problems of its own after extensive testing (having hardware timer and
software timers addressing the same issue was found to cause a race
condition under heavy system load)."

This change originally added PROG_DONE handling, which has been split out
into a separate patch. Also on our platform, the data mover driver maintains
coherency to ensure API reliability, so the above mentioned cache corruption
issue was not an issue for us.

Subject: mmc: msm_sdcc: Fix issue where clocks could be disabled mid
 transaction

msmsdcc_enable_clocks() was incorrectly being called depending on
the state of host->clks_on. This means the busclk idle timer was never
being deleted if the clock was already on.. Bogus.

    Also fixes a possible double clk disable if the call to
del_timer_sync() in msmsdcc_disable_clocks() raced with
the busclk timer.

Subject: DMAENGINE: COH 901 318 fix bytesleft

This makes the function to get the number of bytes left in the
ongoing DMA transaction actually work: the old code did not take
neither lli:s nor queued jobs into account. Also fix a missing
spinlock while we're at it.

Subject: dma: Add timb-dma
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the support for the DMA engine withing the timberdale FPGA.

The DMA channels are strict device to host, or host to device
and can not be used for generic memcpy.

From: Linus Walleij <linus.walleij@stericsson.com>
Date: Fri, 26 Mar 2010 16:44:01 -0700
Subject: DMAENGINE: generic slave control v2

Convert the device_terminate_all() operation on the
DMA engine to a generic device_control() operation
which can now optionally support also pausing and
resuming DMA on a certain channel. Implemented for the
COH 901 318 DMAC as an example.

Subject: DMAENGINE: generic channel status v2

Convert the device_is_tx_complete() operation on the
DMA engine to a generic device_tx_status()operation which
can return three states, DMA_TX_RUNNING, DMA_TX_COMPLETE,
DMA_TX_PAUSED.

Subject: ACPI: pci_root: save downstream bus range

Previously, we only saved the root bus number, i.e., the beginning of the
downstream bus range.  We now support IORESOURCE_BUS resources, so this
patch uses that to keep track of both the beginning and the end of the
downstream bus range.

It's important to know both the beginning and the end for supporting _CBA
(see PCI Firmware spec, rev 3.0, sec 4.1.3) and so we know the limits for
any possible PCI bus renumbering (we can't renumber downstream buses to be
outside the bus number range claimed by the host bridge).

It's clear from the spec that the bus range is supposed to be in _CRS, but
if we don't find it there, we'll assume [_BBN - 0xFF] or [0 - 0xFF].

Subject: ACPI: pci_root: pass acpi_pci_root to arch-specific scan

The acpi_pci_root structure contains all the individual items (acpi_device,
domain, bus number) we pass to pci_acpi_scan_root(), so just pass the
single acpi_pci_root pointer directly.

This will make it easier to add _CBA support later.  For _CBA, we need the
entire downstream bus range, not just the base bus number.  We have that in
the acpi_pci_root structure, so passing the pointer makes it available to
the arch-specific code.

Subject: ds2782_battery: Fix clientdata on removal

Probably due to a copy & paste bug, clientdata was set again to the data
structure (which is freed immediately afterwards) when it should be
NULLed. Just remove the calls as the i2c-core does this automatically
now.

Subject: wm831x_power: Use genirq

Since the WM831x core has been converted to use genirq for the
interrupt controller there is no longer any need for chip specific
wrappers for IRQ operations. Convert to use genirq directly.

intel_map_sg used offset_pfn which was set to zero when invalidating the IOTLB.
intel_map_sg now uses size variable for this matter.

Subject: intel-iommu: Use correct domain ID when caching mode is enabled

In caching-mode mappings of pages (changes from non-present to present)
require invalidation.
Currently, this IOTLB flush is performed with domain ID of zero.
This is not according to the VT-d spec and causes big problems for
emulating software.
This patch uses the correct domain ID in IOTLB flushes.
Device IOTLB invalidation is performed only on present to non-present
changes. This decision is now based on explicit parameter instead of
zero domain-ID.

Subject: intel-iommu: Avoid global flushes with caching mode.

While it may be efficient on real hardware, emulation of global
invalidations is very expensive as all shadow entries must be examined.
This patch changes the behaviour when caching mode is enabled (which is
the case when IOMMU emulation takes place). In this case, page specific
invalidation is used instead.

Subject: firewire: ohci: do not clear PHY interrupt status inadvertently

The interrupt status bits in PHY register 5 are cleared by writing a one
bit.  To avoid clearing them unadvertently, do not write them back when
they were read as set, but only when they have been explicitly requested
to be set.

Subject: firewire: ohci: enable 1394a enhancements

The OHCI spec says that, if the programPhyEnable bit is set, the driver
is responsible for configuring the IEEE1394a enhancements within the PHY
and the link consistently.  So do this.

Also add a quirk to allow disabling these enhancements; this is needed
for the TSB12LV22 where ack accelerations are buggy (erratum b).

Subject: firewire: ohci: fix up configuration of TI chips

On TI chips (OHCI-Lynx and later), enable link enhancements features
that TI recommends to be used.  None of these are required for proper
operation, but they are safe and nice to have.

In theory, these bits should have been set by default, but in practice,
some BIOS/EEPROM writers apparently do not read the datasheet, or get
spooked by names like "unfair".

Subject: firewire: ohci: wait for PHY register accesses to complete

Rather than having the arbitrary msleep(2) pause, let read_phy_reg()
loop until the link--phy access was finished.

Factor write_phy_reg() out of ohci_update_phy_reg() and of
read_paged_phy_reg() and let it loop too until the link--phy access was
finished.

Like in the older ohci1394 driver, a timeout of 100 milliseconds is
chosen.  Unlike the old driver, we sleep instead of busy-wait in each
waiting loop iteration.  Instead of a loop, the waiting could probably
also be implemented interrupt driven, but why bother.  It would require
up and running interrupt handling before the link was fully configured
and enabled.

Also modify functions a bit:  Error return and value return can be
combined in read_phy_reg() since the domain of values is only u8.
Likewise in read_paged_phy_reg().

Subject: firewire: ohci: cleanups and fix for nonstandard build without debug
 facility

1) Clean up two function names:  The ohci_ prefix is only used in names
of fw_card_driver hooks.  There were two unnecessary exceptions.

2) Replace empty macros by empty inline functions so that call parameter
type checking is available in #ifndef'd builds.

3) CONFIG_FIREWIRE_OHCI_DEBUG is currently a hidden kconfig variable,
hence is not going to be switched off by anybody.  Still, it can be
switched off but then compilation will fail in ohci_enable() at the
expression param_debug & OHCI_PARAM_DEBUG_BUSRESETS.  Add the necessary
definitions in the nonstandard case.

Subject: firewire: cdev: mark char device files as not seekable

The <linux/firewire-cdev.h> character device file ABI (i.e. /dev/fw*
character device file interface) does not make any use of lseek(),
pread(), pwrite() (or any kind of write() at all).

Use nonseekable_open() and, redundantly, set file_operations.llseek to
no_llseek to remove any doubt whether the BKL-grabbing default_llseek
handler is used.  (Also shuffle file_operations initialization according
to the order of handler definitions.)

Subject: ieee1394: mark char device files as not seekable

The
  - raw1394   (/dev/raw1394),
  - video1394 (/dev/video1394/*),
  - dv1394    (/dev/dv1394/*)
character device file ABIs do not make any use of lseek(), pread(), or
pwrite().  Therefore use nonseekable_open() and, redundantly, set
file_operations.llseek to no_llseek to remove any doubt whether the BKL-
grabbing default_llseek handler is used.

Although all this is legacy code which should be left in peace until it
is eventually removed (as it is superseded by firewire-core's
<linux/firewire-cdev.h> ABI), this change seems still worth doing to
further minimize the presence of BKL usage in the kernel.

Subject: crypto: mv_cesa - Fix situation where the dest sglist is organized
 differently than the source sglist

Bugfix for situations where the destination scatterlist has a different
buffer structure than the source scatterlist (e.g. source has one 2K
buffer and dest has 2 1K buffers)

Subject: MXC: mxc_nand: set NFC registers after reset

This patch allows the mxc_nand driver to reset the NAND
flash controller.  NFC registers are (re-)set after
completion of the reset, as a reset will have reverted
the NFC registers to their default values.

From: Ivo Clarysse <ivo.clarysse@gmail.com>
Date: Thu, 8 Apr 2010 16:16:51 +0200
Subject: MXC: mxc_nand: support i.MX21

On i.MX21 SoCs, if the NFC_CONFIG1:NFC_INT_MASK bit is set,
NFC_CONFIG2:NFC_INT always reads out zero, even if an
operation is completed.  This patch uses enable_irq and
disable_irq_nosync instead of NFC_CONFIG1:NFC_INT_MASK to
mask NFC interrupts.  This allows NFC_CONFIG2:NFC_INT to also
be used to detect operation completion on i.MX21.

The i.MX21 NFC does not signal reset completion using
NFC_CONFIG1:NFC_INT_MASK, so instead reset completion is
tested by checking if NFC_CONFIG2 becomes 0.

Subject: ARM: MXC: mxcmmc: work around a bug in the SDHC busy line handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MX3 SoCs have a silicon bug which corrupts CRC calculation of
multi-block transfers when connected SDIO peripheral doesn't drive the
BUSY line as required by the specs.

One way to prevent this is to only allow 1-bit transfers.

Another way is playing tricks with the DMA engine, but this isn't
mainline yet. So for now, we live with the performance drawback of 1-bit
transfers until a nicer solution is found.

This patch introduces a new host controller callback 'init_card' which
is for now only called from mmc_sdio_init_card().

Subject: intel-iommu: Fix boot inside 64bit virtualbox with io-apic disabled

Commit 074835f0143b83845af5044af2739c52c9f53808 ("intel-iommu: Fix
kernel hand if interrupt remapping disabled in BIOS") is adding a check
for interrupt remapping disabled and is dereferencing the dmar_tbl
pointer without checking its value.

Unfortunately, this value is null when booting inside a 64bit virtual
box guest with io-apic disabled, leading to a crash. With a check on it,
the guest is now booting. It's triggering a WARN() in
clockevent_delta2ns but it's better than not booting at all and allows
the user to see there's something wrong on their io-apic setup.

Subject: crypto: geode-aes - Fix some code style issues

This fixes some code style issues like:

- Use #include <linux/io.h> instead of <asm/io.h> and #include
  <linux/delay.h> instead of <asm/delay.h>

- Use "foo *bar" instead of "foo * bar"

- Add a space after the for or while sentence and before the open
  parenthesis '('

- Don't use assignments in a if condition

Subject: firewire: core: clean up config ROM related defined constants

Clemens Ladisch pointed out that
  - BIB_IMC is not named like the field is called in the standard,
  - readers of the code may get worried about the magic 0x0c0083c0,
  - a CSR_NODE_CAPABILITIES key is there in the header but not put to
    good use.

So let's rename BIB_IMC, add a defined constant for Node_Capabilities
and a comment which reassures people that somebody thought about it and
they don't have to (or if they still do, tell them where they have to
look for confirmation), and prune our incomplete and arbitrary set of
defined constants of CSR key IDs.  And there is a nother magic number,
that of Bus_Information_Block.Bus_Name, to be defined and commented.

Subject: firewire: core: make transaction label allocation more robust

If one request is so long-lived that it does not get a response before
the following 63 requests, its bit in tlabel_mask is still set when the
next request tries to allocate a transaction label for that number.  In
this state, while the first request is not completed or timed out, no
new requests can be submitted.

To fix this, skip over any label still in use, and do not error out
unless we have entirely run out of labels.

Subject: ACPI: Export EDID blocks to the kernel

The ACPI spec includes a provision for hardware to provide EDID via the
ACPI video extension. In the KMS world it's necessary for a way to obtain
this from within the kernel. Add a function that either returns the EDID
for the provided ACPI display ID or the first display of the provided type.
Also add support for ensuring that devices with legacy IDs are supported.

Subject: pdc202xx_old: ignore "FIFO empty" bit in test_irq() method

The driver takes into account not only the interrupt status bit but
also "FIFO empty" bit in its test_irq() method. This actually is a
superfluous check since for the DMA commands calling the
dma_test_irq() method further in the interrupt handler makes sure FIFO
is emptied.

Subject: of/flattree: Make unflatten_device_tree() safe to call from any arch

This patch makes unflatten_device_tree() safe to call from any arch
setup code with the following changes:
- Make sure initial_boot_params actually points to a device tree blob
  before unflattening
- Make sure the initial_boot_params->magic field is correct
- If CONFIG_OF_FLATTREE is not set, then make unflatten_device_tree()
  an empty static inline function.

This patch also adds some additional debug output to the top of
unflatten_device_tree().

Subject: driver-core: Add device node pointer to struct device

Currently, platforms using CONFIG_OF add a 'struct device_node *of_node'
to dev->archdata.  However, with CONFIG_OF becoming generic for all
architectures, it makes sense for commonality to move it out of archdata
and into struct device proper.

This patch adds a struct device_node *of_node member to struct device
and updates all locations which currently write the device_node pointer
into archdata to also update dev->of_node.  Subsequent patches will
modify callers to use the archdata location and ultimately remove
the archdata member entirely.

From d12d42f744f805a9ccc33cd76f04b237cd83ce56 Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@secretlab.ca>
Date: Tue, 13 Apr 2010 16:12:28 -0700
Subject: i2c/of: Allow device node to be passed via i2c_board_info

The struct device_node *of_node pointer is moving out of dev->archdata
and into the struct device proper.  of_i2c.c needs to set the of_node
pointer before the device is registered.  Since the i2c subsystem
doesn't allow 2 stage allocation and registration of i2c devices, the
of_node pointer needs to be passed via the i2c_board_info structure
so that it is set prior to registration.

This patch adds of_node to struct i2c_board_info (conditional on
CONFIG_OF), sets of_node in i2c_new_device(), and modifies of_i2c.c
to use the new parameter.  The calling of dev_archdata_set_node()
from of_i2c will be removed in a subsequent patch when of_node is
removed from archdata and all users are converted over.

Subject: ioat2,3: convert to producer/consumer locking

Use separate locks for the descriptor prep (producer) and descriptor
cleanup (consumer) paths.  Allows the producer path to run concurrently
with the cleanup path.  Inspired by Documentation/circular-buffer.txt.

Subject: ioat3: disable cacheline-unaligned transfers for raid operations

There are cases where cacheline-unaligned raid operations can hang the
dma channel.  Simply disable these operations by increasing the
alignment constraints published to async_tx.  The raid456 driver always
issues page aligned requests, so the only in-kernel user of the ioatdma
driver that is affected by this change is dmatest.

Subject: ds2782_battery: Get rid of magic numbers in driver_data

Constructions like 'if (id->driver_data == 1)' look quite weird.
This patch introduces 'enum ds278x_num_id', which makes things
much more understandable, i.e. 'if (id->driver_data == DS2786)'.

Subject: wm97xx_battery: Quieten sparse warning (bat_set_pdata not declared)

This patch fixes following sparse warning:

drivers/power/wm97xx_battery.c:311:6: warning: symbol 'wm97xx_bat_set_pdata' was not declared. Should it be static?

Note that we can't just include linux/wm97xx_batt.h because the header
is deprecated, and so this pops up:

In file included from drivers/power/wm97xx_battery.c:22:
include/linux/wm97xx_batt.h:6: warning: #warning This file will be removed soon, use wm97xx.h instead!

Since wm97xx_bat_set_pdata() is also deprecated (in favour of pdata
passed via AC97 bus), just workaround the issue by declaring the
function in wm97xx_battery.c.

Subject: tosa_battery: Fix build error due to direct driver_data usage

The driver isn't buildable since 2.6.32 (i.e. commit b4028437
"Driver core: move dev_get/set_drvdata to drivers/base/dd.c"):

  CC      tosa_battery.o
tosa_battery.c: In function 'tosa_read_bat':
tosa_battery.c:64: error: 'struct device' has no member named 'driver_data'
tosa_battery.c: In function 'tosa_read_temp':
tosa_battery.c:84: error: 'struct device' has no member named 'driver_data'

Nowadays we must not access driver_data directly, use dev_get_drvdata()
instead.

From a0c36a1f0fbab42590dab3c13c10fa7d20e6c2cd Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Mon, 22 Jun 2009 22:41:15 -0300
Subject: i7core_edac: Add an EDAC memory controller driver for Nehalem
 chipsets

This driver is meant to support i7 core/i7core extreme desktop
processors and Xeon 35xx/55xx series with integrated memory controller.
It is likely that it can be expanded in the future to work with other
processor series based at the same Memory Controller design.

For now, it has just a few MCH status reads.

From 194a40feabb7cab38911a357c86e968e98024281 Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Mon, 22 Jun 2009 22:48:28 -0300
Subject: i7core_edac: Add error insertion code for Nehalem

Implements set_inject_error() with the low-level code needed to inject
memory errors at Nehalem, and adds some sysfs nodes to allow error injection

The next patch will add an API for error injection.

Subject: i7core_edac: Registers all supported MC functions

Now, it will try to register on all supported Memory Controller
functions.

It should be noticed that dev3, function 2 is present only on chips with
Registered DIMM's, according to the datasheet. So, the driver doesn't
return -ENODEV is all functions but this one were successfully
registered and enabled:

    EDAC i7core: Registered device 8086:2c18 fn=3 0
    EDAC i7core: Registered device 8086:2c19 fn=3 1
    EDAC i7core: Device not found: PCI ID 8086:2c1a (dev 3, func 2)
    EDAC i7core: Registered device 8086:2c1c fn=3 4
    EDAC i7core: Registered device 8086:2c20 fn=4 0
    EDAC i7core: Registered device 8086:2c21 fn=4 1
    EDAC i7core: Registered device 8086:2c22 fn=4 2
    EDAC i7core: Registered device 8086:2c23 fn=4 3
    EDAC i7core: Registered device 8086:2c28 fn=5 0
    EDAC i7core: Registered device 8086:2c29 fn=5 1
    EDAC i7core: Registered device 8086:2c2a fn=5 2
    EDAC i7core: Registered device 8086:2c2b fn=5 3
    EDAC i7core: Registered device 8086:2c30 fn=6 0
    EDAC i7core: Registered device 8086:2c31 fn=6 1
    EDAC i7core: Registered device 8086:2c32 fn=6 2
    EDAC i7core: Registered device 8086:2c33 fn=6 3

Subject: i7core_edac: need mci->edac_check, otherwise module removal doesn't
 work

There are some locking troubles with edac_core: if you don't declare an
edac_check, module may suffer from soft lock.

Subject: i7core_edac: Add a memory check routine, based on device 3 function 4

This function appears only on Xeon 5500 datasheet. Yet, testing with a
Xeon 3503 showed that this is also implemented on other Nehalem
processors.

At the first read, MC_TEST_ERR_RCV1 and MC_TEST_ERR_RCV0 can contain any
value. Modify CE error logic to update the error count only after the
second read.

An alternative approach would be to do a write at rcv0 and rcv1
registers, but it seemed better to keep they untouched, since BIOS might
eventually assume that they are exclusive for their usage.

Subject: i7core_edac: Memory info fixes and preparation for properly filling
 cswrow data

Now, memory size is properly displayed:

    EDAC i7core: DOD Max limits: DIMMS: 2, 1-ranked, 8-banked
    EDAC i7core: DOD Max rows x colums = 0x4000 x 0x400
    EDAC i7core: Memory channel configuration:
    EDAC i7core: Ch0 phy rd0, wr0 (0x063f7c31): 2 ranks, UDIMMs
    EDAC i7core:    dimm 0 (0x00000288) 1024 Mb offset: 0, numbank: 8,
                    numrank: 1, numrow: 0x4000, numcol: 0x400
    EDAC i7core:    dimm 1 (0x00001288) 1024 Mb offset: 4, numbank: 8,
                    numrank: 1, numrow: 0x4000, numcol: 0x400
    EDAC i7core: Ch1 phy rd1, wr1 (0x063f7c31): 2 ranks, UDIMMs
    EDAC i7core:    dimm 0 (0x00000288) 1024 Mb offset: 0, numbank: 8,
                    numrank: 1, numrow: 0x4000, numcol: 0x400
    EDAC i7core: Ch2 phy rd3, wr3 (0x063f7c31): 2 ranks, UDIMMs
    EDAC i7core:    dimm 0 (0x00000288) 1024 Mb offset: 0, numbank: 8,
                    numrank: 1, numrow: 0x4000, numcol: 0x400

Still, as the way to retrieve csrows info is not known, it does a
mapping of what's available to csrows basic unit at edac core.

Subject: i7core_edac: Add edac_mce glue

Adds a glue code to allow i7core to work with mcelog. With the glue,
i7core registers itself on edac_mce. At mce, when an error is detected,
it calls all registered drivers (in this case, i7core), for EDAC error
handling.

TODO: It currently just prints the MCE error log using about the same
      format as mce panic messages. The error message should be enhanced
      with mcelog userspace info and converted into the proper EDAC format,
      to feed the EDAC error counts.

Subject: i7core_edac: Adds write unlock to MC registers

The public Intel Xeon 5500 volume 2 datasheet describes, on page 53,
session 2.6.7 a register that can lock/unlock Memory Controller the
configuration register, called MC_CFG_CONTROL.

Adds support for it in the hope that software error injection would
work. With my tests with Xeon 35xx, there's still something missing.
With a program that does sequencial bit writes at dev 0.0, sometimes, it
produces error injection, after unblocking the MC_CFG_CONTROL (and,
sometimes, it just locks my testing machine).

I'll try later to discover by trial and error what's the register that
solves this issue on Xeon 35xx.

Subject: i7core_edac: Add a code to probe Xeon 55xx bus

This code changes the detection procedure of i7core_edac. Instead of
directly probing for MC registers, it probes for another register found
on Nehalem. If found, it tries to pick the first MC PCI BUS. This should
work fine with Xeon 35xx, but, on Xeon 55xx, this is at bus 254 and 255
that are not properly detected by the non-legacy PCI methods.

The new detection code scans specifically at buses 254 and 255 for the
Xeon 55xx devices.

This code has not tested yet. After working, a change at the code will
be needed, since the i7core is not yet ready for working with 2 sets of
MC.

Subject: i7core_edac: add support for more than one MC socket

Some Nehalem architectures have more than one MC socket. Socket 0 is
located at bus 255.

Currently, it is using up to 2 sockets, but increasing it to a larger
number is just a matter of increasing MAX_SOCKETS definition.

This seems to be required for properly support of Xeon 55xx.

Still needs testing with Xeon 55xx.

Subject: i7core_edac: decode mcelog error and send it via edac interface

Enriches mcelog error by using the encoded information at MCE status and
misc registers (IA32_MCx_STATUS, IA32_MCx_MISC).

Some fixes are still needed here, in order to properly fill the EDAC
fields.

Subject: i7core_edac: some fixes at memory error parser

m->bank is not related to the memory bank but, instead, to the MCA Error
register bank. Fix it accordingly. While here, improves the comments for
Nehalem bank.

A later fix is needed, in order to get bank/rank information from MCA
error log.

Subject: i7core: fix probing on Xeon55xx

Xeon55xx fails to probe with this error message:

EDAC DEBUG: in drivers/edac/i7core_edac.c, line at 1660: MC: drivers/edac/i7core_edac.c: i7core_init()
EDAC i7core: Device not found: dev 00:00.0 PCI ID 8086:2c41
i7core_edac: probe of 0000:00:14.0 failed with error -22

This is due to the fact that, on Xeon35xx (and i7core), device 00.0 has
PCI ID 8086:2c40.

Subject: i7core: fix get_devices routine for Xeon55xx

i7core_get_devices() were preparet to get just the first found device of each type.
Due to that, on Xeon 55xx, only socket 1 were retrived.

Rework i7core_get_devices() to clean it and to properly support Xeon 55xx.

While here, fix a small typo.

Subject: i7core_edac: fix error injection

There were two stupid error injection bugs introduced by wrong
cut-and-paste: one at socket store, and another at the error inject
register. The last one were causing the code to not work at all.

While here, adds debug messages to allow seeing what registers are being
set while sending error injection.

Subject: i7core_edac: Use Device 3 function 2 to report errors with RDIMM's

Nehalem and upper chipsets provide an special device that has corrected memory
error counters detected with registered dimms. This device is only seen if
there are registered memories plugged.

After this patch, on a machine fully equiped with RDIMM's, it will use the
Device 3 function 2 to count corrected errors instead on relying at mcelog.

For unregistered DIMMs, it will keep the old behavior, counting errors
via mcelog.

This patch were developed together with Keith Mannthey <kmannth@us.ibm.com>

Subject: i7core: Use registered memories per processor

Instead of assuming that the entire machine has either registered or
unregistered memories, do it at CPU socket based.

While here, fix a bug at i7core_mce_output_error(), where the we're
using m->cpu directly as if it would represent a socket. Instead, the
proper socket_id is given by cpu_data[m->cpu].phys_proc_id.

Subject: i7core_edac: Probe on Xeons eariler

On the Xeon 55XX series cpus the pci deives are not exposed via acpi so
we much explicitly probe them to make the usable as a Linux PCI device.

This moves the detection of this state to before pci_register_driver is
called.  Its present position was not working on my systems, the driver
would complain about not finding a specific device.

This patch allows the driver to load on my systems.

Subject: i7core_edac: Improve corrected_error_counts output for RDIMM

Just cosmetics. instead of showing something like:

socket 0, channel 2dimm0: 1
dimm1: 0
dimm2: 0
socket 1, channel 2dimm0: 0
dimm1: 0
dimm2: 0

Show:

socket 0, channel 2 RDIMM0: 1 RDIMM1: 0 RDIMM2: 0
socket 0, channel 2 RDIMM0: 0 RDIMM1: 0 RDIMM2: 0

This is more synthetic and easier to parse.

Subject: Dynamically allocate memory for PCI devices

Instead of using a static table assuming always 2 CPU sockets, allocate
space dynamically for Nehalem PCI devs.

This patch is part of a series of patches that changes i7core_edac to
allow more than 2 sockets and to properly report one memory controller
per socket.

From f47429494fd50c0b7396fe3f8a26ea638b47c5ba Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Sat, 5 Sep 2009 02:35:08 -0300
Subject: i7core_edac: create one mc per socket/QPI

Instead of creating just one memory controller, create one per socket
(e. g. per Quick Link Path Interconnect).

This better reflects the Nehalem architecture.

Subject: i7core_edac: change remove module strategy

The old remove module stragegy didn't work on devices with multiple
cores, since only one PCI device is used to open all mc's, due to
Nehalem nature.

Also, it were based at pdev value. However, this doesn't point to the
pci device used at mci->dev.

So, instead, it unregisters all devices at once, deleting them from the
device list.

Subject: edac_core: Allow the creation of sysfs groups

Currently, all sysfs nodes are stored at /sys/.*/mc. (regex)
However, sometimes it is needed to create attribute groups.

This patch extends edac_core to allow groups creation.

Subject: i7core_edac: Convert UDIMM error counters into a proper sysfs group

Instead of displaying 3 values at the same var, break it into 3
different sysfs nodes:

/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm0
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm1
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm2

For registered dimms, however, the error counters are already being
displayed at:
	/sys/devices/system/edac/mc/mc0/csrow*/ce_count

So, there's no need to add any extra sysfs nodes.

Subject: cmd640: fix kernel oops in test_irq() method

When implementing the test_iqr() method, I forgot that this driver is not an
ordinary PCI driver and also needs to support VLB variant of the chip. Moreover,
'hwif->dev' should be NULL, potentially causing oops in pci_read_config_byte().

Subject: staging: Add driver to support wanPMC-CxT1E1 card.

Obviously still needs serious attention, but it compiles.

Original author: Rick Dobbs

Add driver to support wanPMC-CxT1E1 card.

This card provides 1-4 ports of T1E1 in PMC form factor.

Note, Rick doesn't want his email showing up as the "From:" author, but
has given his blessing to have the code included in the kernel tree.

+     *    Put the data of the requested offset at that
+     *    offset within the buffer.  Return the number (n)
+     *    of bytes there are from the beginning of the
+     *    buffer up to the last byte of data.  If the

+     *    and the reader is prepared to take more data

+     *    offset advanced by the number of bytes
+     *    absorbed.  This interface is useful for files
+     *    no larger than the buffer.
+     * 1) Set *start = an unsigned long value less than
+     *    the buffer address but greater than zero.
+     *    Put the data of the requested offset at the
+     *    beginning of the buffer.  Return the number of
+     *    bytes of data placed there.  If this number is
+     *    greater than zero and you didn't signal eof
+     *    and the reader is prepared to take more data
+     *    you will be called again with the requested
+     *    offset advanced by *start.  This interface is

+     *    of a series of blocks which you want to count
+     *    and return as wholes.
+     *    (Hack by Paul.Russell@rustcorp.com.au)
+     * 2) Set *start = an address within the buffer.
+     *    Put the data of the requested offset at *start.
+     *    Return the number of bytes of data placed there.

Subject: Staging: Remove staging/poch

Remove staging/poch.

Reasons for removal are -- The driver has serious cache
issues, that I couldn't fix. The card vendor is working
on a better replacement for the driver. The driver has
been delayed a lot and development has come to a stand
still.

Subject: staging: hv: Remove Ringbuffer from TODO line

Remove Ringbuffer work line item from TODO file.

The ring buffer in the Hyper-V Linux drivers is used to communicate with
the parent partition running Windows Server 2008 Hyper-V. The ring
buffer functionality on the Hyper-V Linux drivers is written to be
functionally compatible with the ring buffer functionality on the
Hyper-V Server. Consequently, it is not possible to make any changes
that might break the compatibility with server side ring buffer
implementation.

Subject: staging: IIO: Fix uses of spinlocks prior to init in ring
 implementations

Some confusion was caused by the ___iio_init_ring_buffer and equivalent
in ring_sw handling both init of spin locks etc and allocation and
of the actual buffer.  This resulted in ring->use_lock being held
before it was initialized and actually during the initialization.

Some of the recent cleanups in the spin lock code seem to have triggered
the bug actually causing traceable crashes.

The following patch should fix this but hasn't been extensively tested
as of yet and there may well be some side effects I haven't thought of.
Just wanted to get this out there before anyone else runs into it!

removed extern keyword from rtl819x_watchdog_wqcallback.
removed static declaration from variable check_reset_cnt.
changed NumRxOkInPeriod and NumTxOkInPeriod comparison
in function rtl819x_watchdog_wqcallback to 666; we're not on windows.

Subject: staging: rt2860: off by one errors

The code is trying to say that if the offset is higher than the max it
should be set to the max, but there is an off by one bug and it sets it
one passed the end of the array.

From ff13209b00dd4f67f676dd8567a9e95f13f4388c Mon Sep 17 00:00:00 2001

Subject: staging: Intel Restricted Access Region Handler

The Intel Restricted Access Region Handler provides a buffer allocation
mechanism to RAR users.  Since the intended usage model is to lock out
CPU access to RAR (the CPU will not be able to access RAR memory), this
driver does not access RAR memory, and merely keeps track of what areas
of RAR memory are in use.  It has it's own simple allocator that does
not rely on existing kernel allocators (SLAB, etc) since those
allocators are too tightly coupled with the paging mechanism, which isn't
needed for the intended RAR use cases.

An mmap() implementation is provided for debugging purposes to simplify
RAR memory access from the user space.  However, it will effectively be
a no-op when RAR access control is enabled since the CPU will not be
able to access RAR.

This driver should not be confused with the rar_register driver.  That
driver exposes an interface to access RAR registers on the Moorestown
platform.  The RAR handler driver relies on the rar_register driver for
low level RAR register reads and writes.

This patch was generated and built against the latest linux-2.6 master
branch.

+RAR Handler (memrar) Driver TODO Items
+======================================
+
+Maintainer: Ossama Othman <ossama.othman@intel.com>
+
+memrar.h
+--------
+1. This header exposes the driver's user space and kernel space
+   interfaces.  It should be moved to <linux/rar/memrar.h>, or
+   something along those lines, when this memrar driver is moved out
+   of `staging'.
+     a. It would be ideal if staging/rar_register/rar_register.h was
+        moved to the same directory.
+
+memrar_allocator.[ch]
+---------------------
+1. Address potential fragmentation issues with the memrar_allocator.
+
+2. Hide struct memrar_allocator details/fields.  They need not be
+   exposed to the user.
+     a. Forward declare struct memrar_allocator.
+     b. Move all three struct definitions to `memrar_allocator.c'
+        source file.
+     c. Add a memrar_allocator_largest_free_area() function, or
+        something like that to get access to the value of the struct
+        memrar_allocator "largest_free_area" field.  This allows the
+        struct memrar_allocator fields to be completely hidden from
+        the user.  The memrar_handler code really only needs this for
+        statistic gathering on-demand.
+     d. Do the same for the "capacity" field as the
+        "largest_free_area" field.
+
+3. Move memrar_allocator.* to kernel `lib' directory since it is HW
+   neutral.
+     a. Alternatively, use lib/genalloc.c instead.
+     b. A kernel port of Doug Lea's malloc() implementation may also
+        be an option.
+
+memrar_handler.c
+----------------
+1. Split user space interface (ioctl code) from core/kernel code,
+   e.g.:
+     memrar_handler.c -> memrar_core.c, memrar_user.c

Date: Tue, 9 Mar 2010 17:42:17 -0800
Subject: Staging: hv: handle skb allocation failure

Some fixes to receive handling:
  * Dieing with assertion failure when running out of memory is not ok
  * Use newer alloc function to get aligned skb
  * Dropped statistic is supposed to be incremented only by
    driver it was responsible for the drop.

Compile tested only.

Date: Thu, 11 Mar 2010 00:21:20 +0100
Subject: Staging: crystalhd: Whitespace fixes, indentation fixes and 3 changed
 #includes

These patches fixes some whitspace and indentation warnings from
checkpatch.pl

Also these changed #includes:
	bc_dts_glob_lnx.h:43: WARNING: Use #include <linux/param.h> instead of <asm/param.h>
	rystalhd_lnx.h:45: WARNING: Use #include <linux/io.h> instead of <asm/io.h>
	crystalhd_lnx.h:49: WARNING: Use #include <linux/uaccess.h> instead of <asm/uaccess.h>

It all compiles fine, but I don't have the hardware to test with..

Subject: Staging: dt3155: fix wait_ibsyclr function

The wait_ibsyclr function is supposed to return the status of the I2C
cycle.  Currently it will always return FALSE because the IIC_CSR2
register is not re-read in order to update the cached register value.
This results in the NEW_CYCLE bit still being 1.

The current code actually works correctly only because the return
value of {Read|Write}I2C is not checked in the driver.

Fix wait_ibsyclr by actually reading the IIC_CSR2 register to get the
updated status.  While here, change the return type to be an actual
errno instead of the private TRUE/FALSE define and remove the now
obvious comments about the return value.

Also, remove the local variable 'writestat' in WriteI2C and just
return the result of wait_ibsyclr.

gpio_* drivers still need drivers in staging. Yes, that will need to
be fixed, but at least fix compilation for now.

Ok, this should fix it ... or at least make it better an non-issue for
people with non-HTC hardware.

Subject: Staging: rt28xx: Make PCI_{MAP,UNMAP}_SINGLE type-safe

To avoid recurrence of bugs such as <http://bugs.debian.org/575726>,
change the type of the first parameter to linux_pci_{map,unmap}_single()
from void * to struct rt_rtmp_adapter *.  Also do not define the macros
PCI_{MAP,UNMAP}_SINGLE() when building the rt2870sta driver; they are
not used and if they were that would be a bug.

Subject: Staging: otus: Remove mix of tabs and spaces with just tabs in
 ioctl.c

Previously defines had a mix of both tabs and spaces, causing an error
in the checkpatch tool.  These tabs and spaces have been consolidated to
only tabs.

Subject: Staging: otus: hpani: using the wrong variable

We're updating the "HpPriv->ani" array here so we should use that to
determine the end of the for loop.  "HpPriv->ani" has 50 elements and
"wd->regulationTable.allowChannel" has 59 elements.

Subject: Staging: iio: iio-trig-gpio: Remove redundant gpio_request

Remove redundant gpio_request:
The GPIO used as trigger IRQ, is also requested as gpio, but actually never read.

Use platform resource facility to get IRQs numbers and flags.
Make sure this driver can be used with any system IRQ, not necessarily limited to GPIO-IRQs.
Use dev_err(dev...) and friends instead of printk(KERN_ERR...)

From f9a4191cfbe86c5f96a6c6d340ab8bb65fa5c211 Mon Sep 17 00:00:00 2001
From: Lars Lindley <lindley@coyote.org>
Date: Sat, 20 Mar 2010 00:26:45 +0100
Subject: Staging: winbond: mto.c Coding style fixes

I changed all things reported by checkpatch.pl except some long lines
and the use of externs in a .c file. I also removed revision comments
and "commented out" code.

From 152f1bc0517f95f6866046f00c7ef7aff1ca58cd Mon Sep 17 00:00:00 2001
From: Lars Lindley <lindley@coyote.org>
Date: Sat, 20 Mar 2010 20:43:59 +0100
Subject: Staging: winbond: scan_s.h Coding style fixes.

I fixed all things reported by checkpatch.pl except a couple
of long lines and typedefs.
I also removed "commented away" code and a history comment.

From c64ba207ddcb7ea426032ae7166b5f666ea1d3c5 Mon Sep 17 00:00:00 2001
From: Lars Lindley <lindley@coyote.org>
Date: Sun, 21 Mar 2010 17:55:03 +0100
Subject: Staging: winbond: sme_api.h Coding style fixes.

I fixed the things reported by checkpatch.pl except
one long line and a __inline.
I also removed commented away code and versioning comments.

and some "commented away" code.

Subject: Staging: winbond: wb35reg.c Coding style fixes

I fixed the problems reported by checkpatch.pl excetp for
long lines, a couple of printks and some warnings about usb_free_urb(NULL).
I checked for regressions with Dan Carpenters strip_whitespace.pl
and diff and everything looks good.
Generated .o is identical to master.

This is a new patch against master where I fixed up a switch-statement
after comments from Pavel Machek.

Subject: Staging: winbond: wb35rx.c Coding style fixes v2.

New patch that fixes an unclear comment too.

I fixed checkpatch issues except for long lines and printk:s.
I also removed version comments and the () in a return statement.
Generated .o is identical to master and i checked the code with
Dan Carpenters strip_whitespace.pl and diff.

Subject: Staging: wlan-ng: tidy up iw_handler

Use array initialisation technique copied from ipw2200.c.

This should always get the function pointers in the correct place,
without the needed for endless counting, skipping blanks etc.

Subject: Staging: wlan-ng: fix p80211wext_mhz_to_channel for channel 14

Channel 14 is 2484 Mhz (cf p80211wext_channel_to_mhz) so this patch
corrects what seems to be just a typo.

Subject: Staging: wlan-ng: refactor p80211wext.c to reduce text size.

Refactor the wext interface to reduce lines of code & module text size.

- add a helper function p80211wext_getmib
- rename p80211wext_dorequest to p80211wext_setmib
- refactor wext to call the get/set mib helpers and so reduce repeated code.

size reported text reduction :-
   text	   data	    bss	    dec	    hex	filename
   8343	    720	      0	   9063	   2367	p80211wext.o.patch
   9907	    720	      0	  10631	   2987	p80211wext.o.orig

Tested on x86_32 laptop, everything works correctly using NetworkManager,
and iwconfig & iwlist return sensible results when reading from the card.

Subject: Staging: rtl8192su: refactored FirmwareDownload92S

added a new function: FirmwareRequest92S

This function(instead of FirmwareDownload92S) is now responsible for
requesting the firmware.

FirmwareDownload92S is now easier to read, smaller and follows kernel
coding style.

plus cosmetics.

Subject: Staging: vt6656: int.c: Fixed Coding Style issues

Fixed almost all the issues given by checkpatch.pl except for one
warning about an 81 character line, which cannot really be decomposed
(the code is a bit too nested there).

+Description:	The Intel Moorestown Restricted Access Region (RAR)
+		Handler driver exposes an ioctl() based interface that
+		allows a user to reserve and release blocks of RAR
+		memory.
+
+		Note:  A sysfs based one was not appropriate for the
+		RAR handler's usage model.
+
+		=========================================================
+				ioctl() Requests
+		=========================================================
+		RAR_HANDLER_RESERVE
+		-------------------
+		Description:	Reserve RAR block.
+		Type:		struct RAR_block_info
+		Direction:	in/out
+		Errors:		EINVAL (invalid RAR type or size)
+				ENOMEM (not enough RAR memory)
+
+		RAR_HANDLER_STAT
+		----------------
+		Description:	Get RAR statistics.
+		Type:		struct RAR_stat
+		Direction:	in/out
+		Errors:		EINVAL (invalid RAR type)
+
+		RAR_HANDLER_RELEASE
+		-------------------
+		Description:	Release previously reserved RAR block.
+		Type:		32 bit unsigned integer
+				(e.g. uint32_t), i.e the RAR "handle".
+		Direction:	in
+		Errors:		EINVAL (invalid RAR handle)
+
+
+		=========================================================
+			ioctl() Request Parameter Types
+		=========================================================
+		The structures referred to above are defined as
+		follows:
+
+		/**
+		 * struct RAR_block_info - user space struct that
+		 *			   describes RAR buffer
+		 * @type:	Type of RAR memory (e.g.,
+		 *		RAR_TYPE_VIDEO or RAR_TYPE_AUDIO) [in]
+		 * @size:	Requested size of a block in bytes to
+		 *		be reserved in RAR. [in]
+		 * @handle:	Handle that can be used to refer to
+		 *		reserved block. [out]
+		 *
+		 * This is the basic structure exposed to the user
+		 * space that describes a given RAR buffer.  It used
+		 * as the parameter for the RAR_HANDLER_RESERVE ioctl.
+		 * The buffer's underlying bus address is not exposed
+		 * to the user.  User space code refers to the buffer
+		 * entirely by "handle".
+		 */
+		struct RAR_block_info {
+			__u32 type;
+			__u32 size;
+			__u32 handle;
+		};
+
+		/**
+		 * struct RAR_stat - RAR statistics structure
+		 * @type:		Type of RAR memory (e.g.,
+		 *			RAR_TYPE_VIDEO or
+		 *			RAR_TYPE_AUDIO) [in]
+		 * @capacity:		Total size of RAR memory
+		 *			region. [out]
+		 * @largest_block_size:	Size of the largest reservable
+		 *			block. [out]
+		 *
+		 * This structure is used for RAR_HANDLER_STAT ioctl.
+		 */
+		struct RAR_stat {
+			__u32 type;
+			__u32 capacity;
+			__u32 largest_block_size;
+		};
+
+		Lastly, the RAR_HANDLER_RELEASE ioctl expects a
+		"handle" to the RAR block of memory.  It is a 32 bit
+		unsigned integer.

Subject: Staging: rtl8187se: Do not send NULL BSSID events when not associated

If we're not associated, we should not send wireless events to let userspace
know that we just left an ESSID, simply because we havent yet joined it.
If we keep on doing that, wpa_supplicant could receive such events while
actually trying to join an ESSID, and thus decide to stop trying. This leads
to a lot of connection failures as this driver seems to be sending GIWAP
events quite a lot.

Subject: Staging: rtl8187se: Do not mess with carrier settings while scanning

Toggling the link carrier is a non sense and is the grossest locking I can
think of. Moreover, it's giving a completely inaccurate status to userspace
who could for example decide to turn the interface down on carrier off
detection.

Subject: Staging: sources for ST core

Texas Instruments BT, FM and GPS combo chips/drivers
make use of a single TTY to communicate with the chip.
This module constitutes the core logic, TTY ldisc driver
and the exported symbols for registering/unregistering of
the protocol drivers such as BT/FM/GPS.

From d0088ce183ad111b203adc94dcc7dde2a590a198 Mon Sep 17 00:00:00 2001
From: Pavan Savoy <pavan_savoy@ti.com>
Date: Thu, 8 Apr 2010 13:16:54 -0500
Subject: Staging: sources for Init manager module

Kernel Space Init-Manager works along with User-Mode
Init Manager daemon running to maintain the UART state.

Communication between user-space daemon and this module can be
	1. Via the pid written onto sysfs entry
	2. Via the rfkill subsystem

It also is a platform driver with a relevant platform device
in the board-*.c along with the list of BT/FM/GPS chip enable
gpio configuration

Subject: Staging: sources for ST header file

Texas Instruments BT, FM and GPS combo chips/drivers
make use of a single TTY to communicate with the chip.
This is the common header file for both the ST driver and the
protocol drivers which intend to use ST as their mode of
transport.

Subject: Staging: rtl8192e: Use the standard config option for PM functions

Use the standard config option CONFIG_PM to enable rtl8192e PM
functions. Tested on Samsung N140 and it works fine. Without enabling
the PM functions, the box always fails to resume.

Subject: Staging: Yet another (third) dt3155 driver PCI/video4linux compliant

Kernel module (device driver) for dt3155 frame grabber
video4linux2 compliant (finally). Works with "xawtv -f".

======================================================

This driver is written (almost) from scratch, using the
allocator developed for dt3155pci see bellow). The driver
uses videobuf-dma-contig interface modified to use the above
mentioned allocator instead of dma_alloc_coheren().

The first thing to do was to design a new allocator based
on allocating a configurable number of 4MB chunks of memory,
that latter are broken into frame buffers of 768x576 bytes
kept in different FIFOs (queues). As far as the driver autoloads
as a kernel module during kernel boot, the allocation of 4MB
chunks succeeds.

The driver keeps three FIFOs: one for 4MB chunks, one for free
buffers (available for allocations) and one for buffers already
allocated. Allocation/deallocation is done automatically though
the video4linux videobuf subsystem (some pointers to functions
are replaced by driver supplied functions).

Sure, there are problems:

1. The device tested to work with "xawtv -f" either via read()
   method (DT3155_STREAMING not selected), or via mmap() method
   (DT3155_STREAMING is selected) only. This coresponds to either
   cap->capabilities = V4L2_CAP_VIDEO_CAPTURE | V4L2_CAP_READWRITE;
   or
   cap->capabilities = V4L2_CAP_VIDEO_CAPTURE | V4L2_CAP_STREAMING;
   but not when
   cap->capabilities = V4L2_CAP_VIDEO_CAPTURE |
                           V4L2_CAP_STREAMING |
                           V4L2_CAP_READWRITE;
   This is because xawtv calls poll() before starting streaming,
   but videobuf_poll_stream() automatically starts reading if streaming
   is not started.
   This selection is made during kernel configuration (for now).

2. Works for CCIR, but should work for RS-170 (not tested)
   This is made also during kernel configuration.

3. Could work for multiple dt3155 frame grabbers in a PC,
   (private data is allocated during PCI probe() method), but
   is not tested due to lack of a second board.

4. Not tested on a BIG ENDIAN architecture.

5. Many others you could find .... :-)

All critics, comments, suggestions are wellcome.

Subject: Staging: dt3155v4l: add driver to the build

The last patch forgot to add the driver to the Makefile, so it
would not end up getting built.  This resolves that issue.

Subject: Staging: batman-adv: don't have interrupts disabled while sending.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

send_vis_packets() would disable interrupts before calling
dev_queue_xmit() which resulting in a backtrace in local_bh_enable().
Fix this by using kref on the vis_info object so that we can call
send_vis_packets() without holding vis_hash_lock. vis_hash_lock also
used to protect recv_list, so we now need a new lock to protect that
instead of vis_hash_lock.

Also a few checkpatch cleanups.

MIME-Version: 1.0

TQ and HNA records for originators on secondary interfaces were
wrongly being included on the primary interface. Ensure we output a
line for each source interface on every node, so we correctly separate
primary and secondary interface records.

From: Linus Lüssing <linus.luessing@web.de>
Date: Mon, 22 Mar 2010 22:46:15 +0100
Subject: Staging: batman-adv: Fixing wrap-around bug in vis
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the seqno for a vis packet had a wrap around from i.e. 255 to 0,
add_packet() would falsely claim the older packet with the seqno 255 as
newer as the one with the seqno of 0 and would therefore ignore the new
packet. This happens with all following vis packets until the old vis
packet expires after 180 seconds timeout. This patch fixes this issue
and gets rid of these highly undesired 3min. breaks for the vis-server.

Move the exports for the variables that are in range.c into the
file itself.  These variables should be prefixed with comedi_ but
that's for a different patch...

Move only the exports that we actually use into the individual

easier to start cleaning up kcomedilib (i.e. delete most of it.)

Subject: Staging: comedi: kcomedilib: delete dio.c and get.c

Merge these two files into kcomedilib_main.c as they are tiny.

This will also let us get rid of another global symbol in the future.

Subject: Staging: comedi: kcomedilib: comedi_do_insn is now static

No one else calls this function, so mark it static.
Now we can strip out the unneeded functionality in here as well.

Subject: Staging: comedi: kcomedilib: simplify comedi_do_insn()

Now that we know we are only making 2 different types of instructions,
only handle those two types.

Also make the call a bit more typesafe by passing the correct pointer
type.

Subject: Staging: comedi: kcomedilib: make it typesafe

If we really are passing in a struct comedi_device, then say we are,
don't mess around with void pointers for no reason.

This also fixes up the comedi_bond.c driver, which is the only
user of the kcomedilib code.

Subject: Staging: comedi: clean up sparse issues in proc.c

The whole file should be converted to use seqfile, if it's even
still needed.  Or move to debugfs.

Anyway, I fixed up the minor issues here.

Subject: Staging: comedi: __user markup on comedi_fops.c

Hm, what a mess.  I tried to properly mark up the __user pointers,
but for some of these structures, we use them both in the kernel,
and across the user/kernel boundry, which isn't ok.  So we end
up generating a few new sparse warnings in places we were not before,
but the large majority of things are now properly tagged in the fops
file.

The whole ioctl interface needs to be carefully looked at in the future.

From c88c4e4c7a427ee65556f33e6327b604ec209ec3 Mon Sep 17 00:00:00 2001
From: Hank Janssen <hjanssen@microsoft.com>
Date: Tue, 4 May 2010 15:55:05 -0700
Subject: Staging: hv: Added new hv_utils driver with shutdown as first
 functionality

Addition of new driver for Hyper-V called hv_utils.
This driver is intended to support things like KVP, Timesync, Heartbeat etc.

This first release has support for Gracefull shutdown.
e.g. Select shutdown from the Hyper-V main admin screen and the Linux VM
will do a gracefull shutdown.

Subject: Staging: hv: move ASSERT(scmnd) to a more useful location

There's not much point to make sure scmnd is not NULL after an assert
that would dereference scmnd.  The ASSERT()'s should be removed, but
until they are at least they at least can be in the right order.

Subject: Staging: rtl8192su: all rtl8192su chips have the 93c46 eprom

all rtl8192su chips have the 93c46 eprom. (no 93c56)
it it theoretically safe to remove the 93c56 definitions and some unneeded code.
if your device stops working after this patch, please send me a mail
and include some information about your device:
* dmesg
* lsusb -v
* _exact_ chipset (version)
* vendor
* everything else, that may help

plus cosmetics.

+Description:
+		An event driven driver of data capture to an in kernel buffer.
+		May be provided by a device driver that also has an IIO device
+		based on hardware generated events (e.g. data ready) or
+		provided by a separate driver for other hardware (e.g.
+		periodic timer, gpio or high resolution timer).
+		Contains trigger type specific elements. These do not

+
+What:		/sys/bus/iio/devices/device[n]:buffer
+KernelVersion:	2.6.35
+Contact:	linux-iio@vger.kernel.org

+
+What:		/sys/.../device[n]/sampling_frequency
+KernelVersion:	2.6.35
+Contact:	linux-iio@vger.kernel.org
+Description:
+		Some devices have internal clocks.  This parameter sets the
+		resulting sampling frequency.  In many devices this
+		parameter has an effect on input filters etc rather than
+		simply controlling when the input is sampled.  As this
+		effects datardy triggers, hardware buffers and the sysfs
+		direct access interfaces, it may be found in any of the
+		relevant directories.  If it effects all of the above
+		then it is to be found in the base device directory as here.
+
+What:		/sys/.../device[n]/sampling_frequency_available
+KernelVersion:	2.6.35
+Contact:	linux-iio@vger.kernel.org

+Contact:	linux-iio@vger.kernel.org
+Description:
+		If known for a device, offset to be added to in[m]_raw prior
+		to scaling by volt[m]_scale in order to obtain voltage in
+		millivolts.  Not present if the offset is always 0 or unknown.
+		If m is not present, then voltage offset applies to all in
+		channels. May be writable if a variable offset is controlled
+		by the device. Note that this is different to calibbias which
+		is for devices that apply offsets to compensate for variation
+		between different instances of the part, typically adjusted by
+		using some hardware supported calibration procedure.
+
+What:		/sys/.../device[n]/in[_name][m]_offset_available
+KernelVersion:	2.6.35
+Contact:	linux-iio@vger.kernel.org
+Description:

+		Event generated when accel_x0 passes a threshold in correction direction
+		(or stays beyond one). If direction isn't specified, either triggers it.
+		Note driver will assume last p events requested are enabled where p is
+		however many it supports.  So if you want to be sure you have
+		set what you think you have, check the contents of these. Drivers
+		may have to buffer any parameters so that they are consistent when a
+		given event type is enabled a future point (and not those for whatever
+		alarm was previously enabled).

From 375d65db27544a183aed5e14aa2ed487c796c78d Mon Sep 17 00:00:00 2001
From: Alan Cox <alan@linux.intel.com>
Date: Tue, 4 May 2010 20:40:12 +0100
Subject: Staging: rar and memrar updates

rar: perform a clean up pass

- Move to a registration model where each RAR is claimed/unclaimed
- Use that to fix the client stuff (one client per RAR so no need to queue stuff)
- Support unregister so drivers can rmmod themselves safely
- Fix locking hang on calling rar lock from rar callback
- Clean up
- Kerneldoc

Folded in the memrar update as Greg asked

- Fix various unload related bugs
- Use the per RAR allocator/deallocator
- Add kerneldoc

Subject: Staging: hv: transmit scatter gather support

The transmit management of pages was confusing for handling
fragmented SKB's. (But since NETIF_F_SG was never set, the code was never hit).

The parameter AdditionalRequestPageBufferCount is always one,
(and leads to ugly code), so just inline and add comments.

Subject: Staging: comedi: 8255: fix up previous static markings.

Ian pointed out that exported symbols should not be marked as static :)

Fixed this up by properly including the 8255.h file, and fixing
the function prototypes there, as the CONFIG variables were not getting
set so users of the header file were seeing the incorrect function
prototypes.

Now that the 8255.h file is being included properly, we were
using the incorrect function prototypes, which causes a build
warning now.  This fixes it up and preserves the __iomem markings that
sparse wants to see.

RingBufferInit() would always return sucess and instead relied on an
ASSERT() to test for an error condition.  Remove the ASSERT() and
return -EINVAL instead.  The return value of RingBufferInit() was also
never checked, so check it.

Subject: Staging: arlan: delete the driver

It has sat in the staging directory since October of 2009, and no one
has stepped up to take it over, so odds are, no one cares about it
anymore.  So, it is now deleted as scheduled, and documented in the TODO
file.

Subject: Staging: strip: delete the driver

It has sat in the staging directory since October of 2009, and no one
has stepped up to take it over, so odds are, no one cares about it
anymore.  So, it is now deleted as scheduled, and documented in the TODO
file.

-	---help---
-	  Say Y if you have a Metricom radio and intend to use Starmode Radio
-	  IP. STRIP is a radio protocol developed for the MosquitoNet project
-	  to send Internet traffic using Metricom radios.  Metricom radios are
-	  small, battery powered, 100kbit/sec packet radio transceivers, about
-	  the size and weight of a cellular telephone. (You may also have heard
-	  them called "Metricom modems" but we avoid the term "modem" because
-	  it misleads many people into thinking that you can plug a Metricom
-	  modem into a phone line and use it as a modem.)
-
-	  You can use STRIP on any Linux machine with a serial port, although
-	  it is obviously most useful for people with laptop computers. If you
-	  think you might get a Metricom radio in the future, there is no harm
-	  in saying Y to STRIP now, except that it makes the kernel a bit
-	  bigger.
-
-	  To compile this as a module, choose M here: the module will be
-	  called strip.

- * strip.c	This module implements Starmode Radio IP (STRIP)
- *		for kernel-based devices like TTY.  It interfaces between a
- *		raw TTY, and the kernel's INET protocol layers (via DDI).
- *
- * Version:	@(#)strip.c	1.3	July 1997
- *
- * Author:	Stuart Cheshire <cheshire@cs.stanford.edu>
- *
- * Fixes:	v0.9 12th Feb 1996 (SC)
- *		New byte stuffing (2+6 run-length encoding)
- *		New watchdog timer task
- *		New Protocol key (SIP0)
- *		
- *		v0.9.1 3rd March 1996 (SC)
- *		Changed to dynamic device allocation -- no more compile
- *		time (or boot time) limit on the number of STRIP devices.
- *		
- *		v0.9.2 13th March 1996 (SC)
- *		Uses arp cache lookups (but doesn't send arp packets yet)
- *		
- *		v0.9.3 17th April 1996 (SC)
- *		Fixed bug where STR_ERROR flag was getting set unneccessarily
- *		(causing otherwise good packets to be unneccessarily dropped)
- *		
- *		v0.9.4 27th April 1996 (SC)
- *		First attempt at using "&COMMAND" Starmode AT commands
- *		
- *		v0.9.5 29th May 1996 (SC)
- *		First attempt at sending (unicast) ARP packets
- *		
- *		v0.9.6 5th June 1996 (Elliot)
- *		Put "message level" tags in every "printk" statement
- *		
- *		v0.9.7 13th June 1996 (laik)
- *		Added support for the /proc fs
- *
- *              v0.9.8 July 1996 (Mema)
- *              Added packet logging
- *
- *              v1.0 November 1996 (SC)
- *              Fixed (severe) memory leaks in the /proc fs code
- *              Fixed race conditions in the logging code
- *
- *              v1.1 January 1997 (SC)
- *              Deleted packet logging (use tcpdump instead)
- *              Added support for Metricom Firmware v204 features
- *              (like message checksums)
- *
- *              v1.2 January 1997 (SC)
- *              Put portables list back in

- * Note: manual_dev_addr hack
- * 
- * It is not possible to change the hardware address of a Metricom radio,
- * or to send packets with a user-specified hardware source address, thus
- * trying to manually set a hardware source address is a questionable
- * thing to do.  However, if the user *does* manually set the hardware
- * source address of a STRIP interface, then the kernel will believe it,
- * and use it in certain places. For example, the hardware address listed
- * by ifconfig will be the manual address, not the true one.
- * (Both addresses are listed in /proc/net/strip.)
- * Also, ARP packets will be sent out giving the user-specified address as
- * the source address, not the real address. This is dangerous, because
- * it means you won't receive any replies -- the ARP replies will go to
- * the specified address, which will be some other radio. The case where
- * this is useful is when that other radio is also connected to the same
- * machine. This allows you to connect a pair of radios to one machine,
- * and to use one exclusively for inbound traffic, and the other
- * exclusively for outbound traffic. Pretty neat, huh?
- * 
- * Here's the full procedure to set this up:
- * 
- * 1. "slattach" two interfaces, e.g. st0 for outgoing packets,
- *    and st1 for incoming packets
- * 
- * 2. "ifconfig" st0 (outbound radio) to have the hardware address
- *    which is the real hardware address of st1 (inbound radio).
- *    Now when it sends out packets, it will masquerade as st1, and
- *    replies will be sent to that radio, which is exactly what we want.
- * 
- * 3. Set the route table entry ("route add default ..." or
- *    "route add -net ...", as appropriate) to send packets via the st0
- *    interface (outbound radio). Do not add any route which sends packets
- *    out via the st1 interface -- that radio is for inbound traffic only.
- * 
- * 4. "ifconfig" st1 (inbound radio) to have hardware address zero.
- *    This tells the STRIP driver to "shut down" that interface and not
- *    send any packets through it. In particular, it stops sending the
- *    periodic gratuitous ARP packets that a STRIP interface normally sends.
- *    Also, when packets arrive on that interface, it will search the
- *    interface list to see if there is another interface who's manual
- *    hardware address matches its own real address (i.e. st0 in this
- *    example) and if so it will transfer ownership of the skbuff to
- *    that interface, so that it looks to the kernel as if the packet
- *    arrived on that interface. This is necessary because when the
- *    kernel sends an ARP packet on st0, it expects to get a reply on
- *    st0, and if it sees the reply come from st1 then it will ignore
- *    it (to be accurate, it puts the entry in the ARP table, but
- *    labelled in such a way that st0 can't use it).
- * 
- * Thanks to Petros Maniatis for coming up with the idea of splitting
- * inbound and outbound traffic between two interfaces, which turned
- * out to be really easy to implement, even if it is a bit of a hack.
- * 
- * Having set a manual address on an interface, you can restore it
- * to automatic operation (where the address is automatically kept
- * consistent with the real address of the radio) by setting a manual
- * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF"
- * This 'turns off' manual override mode for the device address.
- * 
- * Note: The IEEE 802 headers reported in tcpdump will show the *real*
- * radio addresses the packets were sent and received from, so that you
- * can see what is really going on with packets, and which interfaces
- * they are really going through.

Subject: Staging: wavelan: delete the driver

It has sat in the staging directory since October of 2009, and no one
has stepped up to take it over, so odds are, no one cares about it
anymore.  So, it is now deleted as scheduled, and documented in the TODO
file.

-/************************** DOCUMENTATION ***************************/
-/*
- * This driver provides a Linux interface to the WaveLAN ISA hardware.
- * The WaveLAN is a product of Lucent (http://www.wavelan.com/).
- * This division was formerly part of NCR and then AT&T.
- * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
- *
- * To learn how to use this driver, read the NET3 HOWTO.
- * If you want to exploit the many other functionalities, read the comments
- * in the code.
- *
- * This driver is the result of the effort of many people (see below).
- */
-
-/* ------------------------ SPECIFIC NOTES ------------------------ */
-/*
- * Web page
- * --------
- *	I try to maintain a web page with the Wireless LAN Howto at :
- *	    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
- *
- * SMP
- * ---
- *	We now are SMP compliant (I eventually fixed the remaining bugs).
- *	The driver has been tested on a dual P6-150 and survived my usual
- *	set of torture tests.
- *	Anyway, I spent enough time chasing interrupt re-entrancy during
- *	errors or reconfigure, and I designed the locked/unlocked sections
- *	of the driver with great care, and with the recent addition of
- *	the spinlock (thanks to the new API), we should be quite close to
- *	the truth.
- *	The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
- *	but better safe than sorry (especially at 2 Mb/s ;-).
- *
- *	I have also looked into disabling only our interrupt on the card
- *	(via HACR) instead of all interrupts in the processor (via cli),
- *	so that other driver are not impacted, and it look like it's
- *	possible, but it's very tricky to do right (full of races). As
- *	the gain would be mostly for SMP systems, it can wait...
- *
- * Debugging and options
- * ---------------------
- *	You will find below a set of '#define" allowing a very fine control
- *	on the driver behaviour and the debug messages printed.
- *	The main options are :
- *	o SET_PSA_CRC, to have your card correctly recognised by
- *	  an access point and the Point-to-Point diagnostic tool.
- *	o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
- *	  (otherwise we always start afresh with some defaults)
- *
- * wavelan.o is too darned big
- * ---------------------------
- *	That's true!  There is a very simple way to reduce the driver
- *	object by 33%!  Comment out the following line:
- *		#include <linux/wireless.h>
- *	Other compile options can also reduce the size of it...
- *
- * MAC address and hardware detection:
- * -----------------------------------
- *	The detection code for the WaveLAN checks that the first three
- *	octets of the MAC address fit the company code.  This type of
- *	detection works well for AT&T cards (because the AT&T code is
- *	hardcoded in wavelan.h), but of course will fail for other
- *	manufacturers.
- *
- *	If you are sure that your card is derived from the WaveLAN,
- *	here is the way to configure it:
- *	1) Get your MAC address
- *		a) With your card utilities (wfreqsel, instconf, etc.)
- *		b) With the driver:
- *			o compile the kernel with DEBUG_CONFIG_INFO enabled
- *			o Boot and look the card messages
- *	2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
- *	3) Compile and verify
- *	4) Send me the MAC code.  I will include it in the next version.
- *

-
-/* --------------------- WIRELESS EXTENSIONS --------------------- */
-/*
- * This driver is the first to support "wireless extensions".
- * This set of extensions provides a standard way to control the wireless
- * characteristics of the hardware.  Applications such as mobile IP may
- * take advantage of it.
- *
- * It might be a good idea as well to fetch the wireless tools to
- * configure the device and play a bit.

-/* --------------------------- HISTORY --------------------------- */
-/*
- * This is based on information in the drivers' headers. It may not be
- * accurate, and I guarantee only my best effort.
- *
- * The history of the WaveLAN drivers is as complicated as the history of
- * the WaveLAN itself (NCR -> AT&T -> Lucent).
- *
- * It all started with Anders Klemets <klemets@paul.rutgers.edu>
- * writing a WaveLAN ISA driver for the Mach microkernel.  Girish
- * Welling <welling@paul.rutgers.edu> had also worked on it.
- * Keith Moore modified this for the PCMCIA hardware.
- *
- * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
- * and added specific PCMCIA support (there is currently no equivalent
- * of the PCMCIA package under BSD).
- *
- * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
- *
- * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
- *
- * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
- * (with help of the BSDI PCMCIA driver) for PCMCIA.
- * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
- * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
- * 2.00 cards correctly (2.4 GHz with frequency selection).
- * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
- * PCMCIA package (and bug corrections).
- *
- * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
- * patches to the PCMCIA driver.  Later, I added code in the ISA driver
- * for Wireless Extensions and full support of frequency selection
- * cards.  Then, I did the same to the PCMCIA driver, and did some
- * reorganisation.  Finally, I came back to the ISA driver to
- * upgrade it at the same level as the PCMCIA one and reorganise
- * the code.
- * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
- * much needed information on the WaveLAN hardware.

- *
- * Changes made for release in 2.5.35 :
- * ----------------------------------
- *	- Set dev->trans_start to avoid filling the logs
- *	- Handle better spurious/bogus interrupt
- *	- Avoid deadlocks in mmc_out()/mmc_in()
- *
- * Wishes & dreams:
- * ----------------
- *	- roaming (see Pcmcia driver)

-/************************** DOCUMENTATION **************************/
-/*
- * This driver provide a Linux interface to the Wavelan Pcmcia hardware
- * The Wavelan is a product of Lucent (http://www.wavelan.com/).
- * This division was formerly part of NCR and then AT&T.
- * Wavelan are also distributed by DEC (RoamAbout DS)...
- *
- * To know how to use this driver, read the PCMCIA HOWTO.
- * If you want to exploit the many other fonctionalities, look comments
- * in the code...
- *
- * This driver is the result of the effort of many peoples (see below).
- */
-
-/* ------------------------ SPECIFIC NOTES ------------------------ */
-/*
- * Web page
- * --------
- *	I try to maintain a web page with the Wireless LAN Howto at :
- *	    http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
- *
- * SMP
- * ---
- *	We now are SMP compliant (I eventually fixed the remaining bugs).
- *	The driver has been tested on a dual P6-150 and survived my usual
- *	set of torture tests.
- *	Anyway, I spent enough time chasing interrupt re-entrancy during
- *	errors or reconfigure, and I designed the locked/unlocked sections
- *	of the driver with great care, and with the recent addition of
- *	the spinlock (thanks to the new API), we should be quite close to
- *	the truth.
- *	The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
- *	but better safe than sorry (especially at 2 Mb/s ;-).
- *
- *	I have also looked into disabling only our interrupt on the card
- *	(via HACR) instead of all interrupts in the processor (via cli),
- *	so that other driver are not impacted, and it look like it's
- *	possible, but it's very tricky to do right (full of races). As
- *	the gain would be mostly for SMP systems, it can wait...
- *
- * Debugging and options
- * ---------------------
- *	You will find below a set of '#define" allowing a very fine control
- *	on the driver behaviour and the debug messages printed.
- *	The main options are :
- *	o WAVELAN_ROAMING, for the experimental roaming support.
- *	o SET_PSA_CRC, to have your card correctly recognised by
- *	  an access point and the Point-to-Point diagnostic tool.
- *	o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
- *	  (otherwise we always start afresh with some defaults)
- *
- * wavelan_cs.o is darn too big
- * -------------------------
- *	That's true ! There is a very simple way to reduce the driver
- *	object by 33% (yes !). Comment out the following line :
- *		#include <linux/wireless.h>
- *	Other compile options can also reduce the size of it...
- *
- * MAC address and hardware detection :
- * ----------------------------------
- *	The detection code of the wavelan chech that the first 3
- *	octets of the MAC address fit the company code. This type of
- *	detection work well for AT&T cards (because the AT&T code is
- *	hardcoded in wavelan_cs.h), but of course will fail for other
- *	manufacturer.
- *
- *	If you are sure that your card is derived from the wavelan,
- *	here is the way to configure it :
- *	1) Get your MAC address
- *		a) With your card utilities (wfreqsel, instconf, ...)
- *		b) With the driver :
- *			o compile the kernel with DEBUG_CONFIG_INFO enabled
- *			o Boot and look the card messages
- *	2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan_cs.h)
- *	3) Compile & verify
- *	4) Send me the MAC code - I will include it in the next version...
- *
- */
-
-/* --------------------- WIRELESS EXTENSIONS --------------------- */
-/*
- * This driver is the first one to support "wireless extensions".
- * This set of extensions provide you some way to control the wireless
- * caracteristics of the hardware in a standard way and support for
- * applications for taking advantage of it (like Mobile IP).
- *
- * It might be a good idea as well to fetch the wireless tools to
- * configure the device and play a bit.

-/* --------------------------- HISTORY --------------------------- */
-/*
- * The history of the Wavelan drivers is as complicated as history of
- * the Wavelan itself (NCR -> AT&T -> Lucent).
- *
- * All started with Anders Klemets <klemets@paul.rutgers.edu>,
- * writing a Wavelan ISA driver for the MACH microkernel. Girish
- * Welling <welling@paul.rutgers.edu> had also worked on it.
- * Keith Moore modify this for the Pcmcia hardware.
- *
- * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
- * and add specific Pcmcia support (there is currently no equivalent
- * of the PCMCIA package under BSD...).
- *
- * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD.
- *
- * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
- *
- * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
- * (with help of the BSDI PCMCIA driver) for PCMCIA.
- * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
- * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
- * correctly 2.00 cards (2.4 GHz with frequency selection).
- * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
- * Pcmcia package (+ bug corrections).
- *
- * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
- * patchs to the Pcmcia driver. After, I added code in the ISA driver
- * for Wireless Extensions and full support of frequency selection
- * cards. Now, I'm doing the same to the Pcmcia driver + some
- * reorganisation.
- * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
- * much needed informations on the Wavelan hardware.

Subject: Staging: netwave: delete the driver

It has sat in the staging directory since October of 2009, and no one
has stepped up to take it over, so odds are, no one cares about it
anymore.  So, it is now deleted as scheduled, and documented in the TODO
file.

- * Filename:      netwave_cs.c
- * Version:       0.4.1
- * Description:   Netwave AirSurfer Wireless LAN PC Card driver
- * Status:        Experimental.
- * Authors:       John Markus Bjørndalen <johnm@cs.uit.no>
- *                Dag Brattli <dagb@cs.uit.no>
- *                David Hinds <dahinds@users.sourceforge.net>

- *
- * Revision History:
- *
- *   08-Nov-97 15:14:47   John Markus Bjørndalen <johnm@cs.uit.no>
- *    - Fixed some bugs in netwave_rx and cleaned it up a bit.
- *      (One of the bugs would have destroyed packets when receiving
- *      multiple packets per interrupt).
- *    - Cleaned up parts of newave_hw_xmit.
- *    - A few general cleanups.
- *   24-Oct-97 13:17:36   Dag Brattli <dagb@cs.uit.no>
- *    - Fixed netwave_rx receive function (got updated docs)
- *   Others:
- *    - Changed name from xircnw to netwave, take a look at
- *      http://www.netwave-wireless.com
- *    - Some reorganizing of the code
- *    - Removed possible race condition between interrupt handler and transmit
- *      function
- *    - Started to add wireless extensions, but still needs some coding
- *    - Added watchdog for better handling of transmission timeouts
- *      (hopefully this works better)

A semicolon is missing at the end of a statement, but it does compile
fine without it as the macro BCMLOG_ERR expands to a do {...} while (0);

Subject: PCI: create function symlinks in /sys/bus/pci/slots/N/

Create convenience symlinks in sysfs, linking slots to device
functions, and vice versa. These links make it easier for users to
figure out which devices actually live in what slots.

For example:

sapphire:/sys/bus/pci/slots # ls
1  10  2  3  4  5  6  7  8  9

sapphire:/sys/bus/pci/slots # ls -l 3
total 0
-r--r--r-- 1 root root 65536 Aug 18 14:10 address
lrwxrwxrwx 1 root root     0 Aug 18 14:10 function0 ->
../../../../devices/pci0000:23/0000:23:01.0
lrwxrwxrwx 1 root root     0 Aug 18 14:10 function1 ->
../../../../devices/pci0000:23/0000:23:01.1

sapphire:/sys/bus/pci/slots # ls -l 3/function0/slot
lrwxrwxrwx 1 root root 0 Aug 18 14:13 3/function0/slot ->
../../../bus/pci/slots/3

The original form of this patch was written by Matthew Wilcox,
and was enhanced to include links from the sysfs slots/ directory
pointing back at the device functions.

Subject: PCI: aerdrv: cleanup inconsistent functions

This cleanup solves some minor naming issues by removing unuseful
function aer_delete_rootport() and by renaming disable_root_aer()
to aer_disable_rootport().

- Inconsistent location of alloc & free:
   The struct rpc is allocated in aer_alloc_rpc() at aerdrv.c
   while it is implicitly freed in aer_delete_rootport() at
   aerdrv_core.c.

- Inconsistent function name:
   It makes a bit confusion that aer_delete_rootport() is seemed
   to be paired with aer_enable_rootport(), i.e. there is neither
   "add" against "delete" nor "disable" against "enable".

Subject: PCI: aerdrv: rework find_source_device

Return bool to indicate that the source device is found or not.
This allows us to skip calling aer_process_err_devices() if we can.

And move dev_printk for debug into this function.

v2: return bool instead of int

Subject: PCI: aerdrv: rework aer_isr_one_error()

Divide tricky for-loop into readable if-blocks.

The logic to set multi_error_valid (to force walking pci bus
hierarchy to find 2nd~ error devices) is changed too, to check
MULTI_{,_UN}COR_RCV bit individually and to force walk only when
it is required.

And rework setting e_info->severity for uncorrectable, not to use
magic numbers.

Subject: PCI: aerdrv: rework get_e_source()

Current get_e_source() returns pointer to an element of array.
However since it also progress consume counter, it is possible
that the element is overwritten by newly produced data before
the element is really consumed.

This patch changes get_e_source() to copy contents of the element
to address pointed by its caller.  Once copied the element in
array can be consumed.

And relocate this function to more innocuous place.

Subject: PCI: aerdrv: remove is_downstream

The pcie->port of port service device points the port associated
the service with.  The find_aer_service iterates over children of
given port udev.

So it is clear that the pcie->port of port service of given port
udev must always point the udev.

Therefore we can know the type of udev without checking its children.

aer-inject, aer_root_reset() is called as reset_link for a
downstream port at upstream of the endpoint:

  pcieport 0000:00:06.0: AER: Uncorrected (Fatal) error received: id=5401
   :
  pcieport 0000:52:02.0: Root Port link has been reset

It externally appears to be working, but internally issues some
accesses to PCI_ERR_ROOT_COMMAND/STATUS registers that is for
root port so not available on downstream port.

This patch introduces default_downstream_reset_link that is
a version of aer_root_reset() with no accesses to root port's
register. It is used for downstream ports that has no reset_link
function its specific.

This patch also updates related description in pcieaer-howto.txt.
Some minor fixes are included.

If we haven't set the module to MODULE_ACTIVE state before (in general,
no interface has yet been added to batman-adv) then the hna table is not
initialised yet. If the kernel changes the mac address of the bat0
interface at this moment then an hna_local_add() called by interface_set_mac_addr()
then resulted in a null pointer derefernce. With this patch we are now
explicitly checking before if the state is MODULE_ACTIVE right now so
that we can assume having an initialised hna table.

Subject: Staging: batman-adv: Clone shared bat packets before modifying them

"tcpdump" and "batctl td" will receive packets with a wrong sequence
number on systems with a different endianess than network byte order.
This happens due to the reordering of bytes in the function which
handles aggregated bat packets. The function which receives the bat
packets must ensure that these buffers aren't shared with anything else
before that function tries to write into it. Otherwise it has to copy
the buffers so it is save again to change them.

Subject: Staging: batman-adv: fix aggregation timing bug
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

batman-adv aggregates routing packets to reduce the number of packets in
the air. Every outgoing packet is compared with other packets in the
buffer to determine whether it can be aggregated or not. Packets sent
at a lower interval can be held back longer to maximize the aggregation.
Due to insufficient checking batman-adv held back all packets for a
certain time depending on its own lowest interval rate which slowed
down all other nodes.

Subject: Staging: batman-adv: Fix aggregation direct-link bug
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

So far, neighbour's secondary interface OGMs can involuntarily
piggyback on primary interface OGMs that arrived on the same secondary
interface before. Secondary interface OGMs should NEVER leave their
direct neighbour broadcast domain! This patch ensures that secondary
interface OGMs can only be aggregated to other secondary interface OGMs.

Max address is not being used anywhere and just misleading, therefore
removing it. VIS_FORMAT string is now obsolete, so also remove it.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We are now having a newer, more neutral vis output so that we won't have
to change the kernelmodule for adding support of new vis output formats.
This patch adds an explanation about this in the README file of
batman-adv and removes the description about the dot/json format (they
will be added to the README of batctl).

+
+The raw format consists of comma seperated values per entry where each
+entry is giving information about a certain source interface. Each entry
+can/has to have the following values:
+-> "mac" -> mac address of an originator's source interface
+           (each line begins with it)
+-> "TQ mac value" -> src mac's link quality towards mac address of a neighbor
+                     originator's interface which is being used for routing
+-> "HNA mac" -> HNA announced by source mac
+-> "PRIMARY" -> this is a primary interface
+-> "SEC mac" -> secondary mac address of source (requires preceeding
+-> PRIMARY)
+
+The TQ value has a range from 4 to 255 with 255 being the best.
+The HNA entries are showing which hosts are connected to the mesh via bat0
+or being bridged into the mesh network.
+The PRIMARY/SEC values are only applied on primary interfaces
+
+---
 In very mobile scenarios, you might want to adjust the originator
 interval to a lower value. This will make the mesh more responsive to
 topology changes, but will also increase the overhead. Please make sure

The code here is testing to see if "i" is passed the end of the array.
The original code works probably, but it's not the cleanest way.

Andrew Lunn suggested that I also remove all the hard coded references
to 256 so I have done that as well.

From 47fdf097c348673dced571da8a15939005219da0 Mon Sep 17 00:00:00 2001
From: Marek Lindner <lindner_marek@yahoo.de>

Subject: Staging: batman-adv: convert multiple /proc files to use sysfs

This is the first patch in a series of patches which aim to convert
all batman-adv /proc files to sysfs. To keep the changes in a
digestable size it has been split up into smaller chunks. During
the transition period batman-adv will use /proc as well as sysfs.

As a first step the following files have been converted:
aggregate_ogm, originators, transtable_global, transtable_local

From 208e13e4297a1d9b986aa371c4529df7dda1c835 Mon Sep 17 00:00:00 2001
From: Marek Lindner <lindner_marek@yahoo.de>
Date: Fri, 7 May 2010 21:47:22 +0200
Subject: Staging: batman-adv: move /proc interface handling to /sys

Instead of having a single /proc file "interfaces" in which you have
to echo the wanted interface batman-adv will create a subfolder in each
suitable /sys/class/net folder. This subfolder contains files for the
interface specific settings. For example, mesh_iface to add/remove an
interface from a virtual mesh network (at the moment only bat0 is
supported).

Example:
echo bat0 > /sys/class/net/eth0/batman-adv/mesh_iface

to deactivate:
echo none > /sys/class/net/eth0/batman-adv/mesh_iface

Interfaces which are not compatible with batman-adv won't contain the
batman-adv folder, therefore can't be activated. Not supported are:
loopback, non-ethernet, non-ARP and virtual mesh network interfaces

Subject: Staging: batman-adv: Reorganize sequence number handling

BATMAN and broadcast packets are tracked with a sequence number window of
currently 64 entries to measure and avoid duplicates. Packets which have a
sequence number smaller than the newest received packet minus 64 are not
within this sequence number window anymore and are called "old packets"
from now on.

When old packets are received, the routing code assumes that the host of the
originator has been restarted. This assumption however might be wrong as
packets can also be delayed by NIC drivers, e.g. because of long queues or
collision detection in dense WiFi? environments. This behaviour can be
reproduced by doing a broadcast ping flood in a dense node environment.

The effect is that the sequence number window is jumping forth and back,
accepting and forwarding any packet (because packets are assumed to be "new")
and causing loops.

To overcome this problem, the sequence number handling has been reorganized.
When an old packet is received, the window is reset back only once. Other old
packets are dropped for (currently) 30 seconds to "protect" the new sequence
number and avoid the hopping as described above.

The reorganization brings some code cleanups (at least i hope you feel the
same) and also fixes a bug in count_real_packets() which falsely updated
the last_real_seqno for slightly older packets within the seqno window
if they are no duplicates.

This second version of the patch also fixes a problem where for seq_diff==64
bit_shift() reads from outside of the seqno window, and removes the loop
for seq_diff == -64 which was present in the first patch.

The third iteration also adds a window for the next expected sequence numbers.
This minimizes sequence number flapping for packets with very big differences
(e.g. 3 packets with seqno 0, 25000 and 50000 might still cause problems
without this window).

Subject: Staging: batman-adv: Limit queue lengths for batman and broadcast
 packets

This patch limits the queue lengths of batman and broadcast packets. BATMAN
packets are held back for aggregation and jittered to avoid interferences.
Broadcast packets are stored to be sent out multiple times to increase
the probability to be received by other nodes in lossy environments.

Especially in extreme cases like broadcast storms, the queues have been seen
to run full, eating up all the memory and triggering the infamous OOM killer.
With the queue length limits introduced in this patch, this problem is
avoided.

Each queue is limited to 256 entries for now, resulting in 1 MB of maximum
space available in total for typical setups (assuming one packet including
overhead does not require more than 2000 byte). This should also be reasonable
for smaller routers, otherwise the defines can be tweaked later.

This third version of the patch does not increase the local broadcast
sequence number when the queue is already full.

As we always return that the we consumed the skb, we should also free the skb
in the case of an error.

Subject: Staging: batman-adv: Update pointer to ethhdr after skb_copy

We must ensure that all pointer to a socket buffer are updated when we
copy a socket buffer and free our reference to the old one.
Another part of the kernel could also free its reference which maybe
removes the buffer completely. In that situation we would would feed
wrong information to the routing algorithm after the memory area is
written again by someone else.

Subject: Staging: batman-adv: Fix whitespace problems criticized by
 checkpatch.pl

Trailing spaces at the end of a line or before a tab are against
Documentation/CodingStyle "3.1: Spaces" and should be avoided. It is
also common style to add a single space after commas unless it is
followed either by a newline or a tab.

 BATMAN-ADV
 ----------
 
-Batman-advanced is a new approach to wireless networking which does no longer
-operate on the IP basis. Unlike B.A.T.M.A.N, which exchanges information
-using UDP packets and sets routing tables, batman-advanced operates on ISO/OSI
-Layer 2 only and uses and routes (or better: bridges) Ethernet Frames. It
-emulates a virtual network switch of all nodes participating. Therefore all
-nodes appear to be link local, thus all higher operating protocols won't be
-affected by any changes within the network. You can run almost any protocol
-above B.A.T.M.A.N. Advanced, prominent examples are: IPv4, IPv6, DHCP, IPX.

+Batman advanced was implemented as a Linux kernel driver  to  re-
+duce the overhead to a minimum. It does not depend on any (other)
+network driver, and can be used on wifi as well as ethernet  lan,
+vpn,  etc ... (anything with ethernet-style layer 2).
 
-USAGE
------
+CONFIGURATION
+-------------
 
-insmod the batman-adv.ko in your kernel:
+Load the batman-adv module into your kernel:
 
 # insmod batman-adv.ko
 
-the module is now waiting for activation. You must add some interfaces
-on which batman can operate. Each interface must be added separately:
+The  module  is now waiting for activation. You must add some in-
+terfaces on which batman can operate. After  loading  the  module
+batman  advanced  will scan your systems interfaces to search for
+compatible interfaces. Once found, it will create  subfolders  in
+the /sys directories of each supported interface, e.g.
 
-# echo wlan0 > /proc/net/batman-adv/interfaces
+# ls /sys/class/net/eth0/batman_adv/
+# iface_status  mesh_iface
 
-( # echo wlan1 > /proc/net/batman-adv/interfaces )
-( # echo eth0 > /proc/net/batman-adv/interfaces )
-( ... )
+If an interface does not have the "batman_adv" subfolder it prob-
+ably is not supported. Not supported  interfaces  are:  loopback,
+non-ethernet and batman's own interfaces.
 
-Now batman starts broadcasting on this interface.
-You can now view the table of originators (mesh participants) with:
+Note:  After the module was loaded it will continuously watch for
+new interfaces to verify the compatibility. There is no  need  to
+reload the module if you plug your USB wifi adapter into your ma-
+chine after batman advanced was initially loaded.
 
-# cat /proc/net/batman-adv/originators
+To activate a  given  interface  simply  write  "bat0"  into  its
+"mesh_iface" file inside the batman_adv subfolder:
 
-The module will create a new interface "bat0", which can be used as a
-regular interface:
+# echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface
 
-# ifconfig bat0 inet 192.168.0.1 up
-# ping 192.168.0.2
-...
+Repeat  this step for all interfaces you wish to add.  Now batman
+starts using/broadcasting on this/these interface(s).
 
----
-If you want topology visualization, your meshnode must be configured
-as VIS-server:
+By reading the "iface_status" file you can check its status:
 
-# echo "server" > /proc/net/batman-adv/vis_server
+# cat /sys/class/net/eth0/batman_adv/iface_status
+# active
 
-Each node is either configured as "server" or as "client" (default:
-"client"). Clients send their topology data to the server next to them,
-and server synchronize with other servers. If there is no server
-configured (default) within the mesh, no topology information will be
-transmitted. With these "synchronizing servers", there can be 1 or
-more vis servers sharing the same (or at least very similar) data.
+To deactivate an interface you have  to  write  "none"  into  its
+"mesh_iface" file:
 
-When configured as server, you can get a topology snapshot of your mesh:
+# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
 
-# cat /proc/net/batman-adv/vis_data
 
-This raw output is intended to be easily parsable and convertable with
-other tools. Have a look at the batctl README if you want a vis output
-in dot or json format for instance and how those outputs could then be
-visualised in an image.
+All  mesh  wide  settings  can be found in batman's own interface
+folder:
+
+#  ls  /sys/class/net/bat0/mesh/
+#  aggregate_ogm   originators        transtable_global  vis_mode
+#  orig_interval   transtable_local   vis_data
+
+
+Some of the files contain all sort of status information  regard-
+ing  the  mesh  network.  For  example, you can view the table of
+originators (mesh participants) with:
+
+# cat /sys/class/net/bat0/mesh/originators
+
+Other files allow to change batman's behaviour to better fit your
+requirements.  For instance, you can check the current originator
+interval (value in milliseconds which determines how often batman
+sends its broadcast packets):
+
+# cat /sys/class/net/bat0/mesh/orig_interval
+# status: 1000
+
+and also change its value:
+
+# echo 3000 > /sys/class/net/bat0/mesh/orig_interval
 
-The raw format consists of comma seperated values per entry where each
-entry is giving information about a certain source interface. Each entry
-can/has to have the following values:
--> "mac" -> mac address of an originator's source interface
-           (each line begins with it)
--> "TQ mac value" -> src mac's link quality towards mac address of a neighbor
-                     originator's interface which is being used for routing
--> "HNA mac" -> HNA announced by source mac
--> "PRIMARY" -> this is a primary interface
--> "SEC mac" -> secondary mac address of source (requires preceeding
--> PRIMARY)
-
-The TQ value has a range from 4 to 255 with 255 being the best.
-The HNA entries are showing which hosts are connected to the mesh via bat0
-or being bridged into the mesh network.
-The PRIMARY/SEC values are only applied on primary interfaces
-
----
 In very mobile scenarios, you might want to adjust the originator
-interval to a lower value. This will make the mesh more responsive to
-topology changes, but will also increase the overhead. Please make sure
-that all nodes in your mesh use the same interval. The default value
-is 1000 ms (1 second).
+interval to a lower value. This will make the mesh  more  respon-
+sive to topology changes, but will also increase the overhead.
+
+
+USAGE
+-----
+
+To  make use of your newly created mesh, batman advanced provides
+a new interface "bat0" which you should use from this  point  on.
+All  interfaces  added  to  batman  advanced are not relevant any
+longer because batman handles them for you. Basically, one "hands
+over" the data by using the batman interface and batman will make
+sure it reaches its destination.
 
-# echo 1000 > /proc/net/batman-adv/orig_interval
+The "bat0" interface can be used like any  other  regular  inter-
+face.  It needs an IP address which can be either statically con-
+figured or dynamically (by using DHCP or similar services):
 
-To deactivate batman, do:
+# NodeA: ifconfig bat0 192.168.0.1
+# NodeB: ifconfig bat0 192.168.0.2
+# NodeB: ping 192.168.0.1
+
+Note:  In  order to avoid problems remove all IP addresses previ-
+ously assigned to interfaces now used by batman advanced, e.g.
+
+# ifconfig eth0 0.0.0.0
+
+
+VISUALIZATION
+-------------
+
+If you want topology visualization, at least one mesh  node  must
+be configured as VIS-server:
+
+# echo "server" > /sys/class/net/bat0/mesh/vis_mode
+
+Each  node  is  either configured as "server" or as "client" (de-
+fault: "client").  Clients send their topology data to the server
+next to them, and server synchronize with other servers. If there
+is no server configured (default) within the  mesh,  no  topology
+information   will  be  transmitted.  With  these  "synchronizing
+servers", there can be 1 or more vis servers sharing the same (or
+at least very similar) data.
+
+When  configured  as  server,  you can get a topology snapshot of
+your mesh:
+
+# cat /sys/class/net/bat0/mesh/vis_data
+
+This raw output is intended to be easily parsable and convertable
+with  other tools. Have a look at the batctl README if you want a
+vis output in dot or json format for instance and how those  out-
+puts could then be visualised in an image.
+
+The raw format consists of comma separated values per entry where
+each entry is giving information about a  certain  source  inter-
+face.  Each  entry can/has to have the following values:
+-> "mac" - mac address of an originator's source interface
+           (each line begins with it)
+-> "TQ mac  value"  -  src mac's link quality towards mac address
+                       of a neighbor originator's interface which
+                       is being used for routing
+-> "HNA mac" - HNA announced by source mac
+-> "PRIMARY" - this  is a primary interface
+-> "SEC mac" - secondary mac address of source
+               (requires preceding PRIMARY)
+
+The TQ value has a range from 4 to 255 with 255 being  the  best.
+The HNA entries are showing which hosts are connected to the mesh
+via bat0 or being bridged into the mesh network.  The PRIMARY/SEC
+values are only applied on primary interfaces

Subject: staging: dt3155v4l syncronize with API changes

dt3155v4l driver, as in -rc6-next-20100506 compiles, but will
not run properly due to recent changes in the videobuf APIs.

This patch synchronizes some functions that have been copied
from drivers/media/video/videobuf-dma-contig.c (and modified)
with the recent (-rc6 -> -rc6-next-) changes in videobuf layer
especially drivers/media/video/videobuf-dma-contig.c

From e390b07bc50fc96caa15c594374782e472c27419 Mon Sep 17 00:00:00 2001
From: Matthias Brugger <mensch0815@googlemail.com>

Subject: staging: adis16255 - TODO issues resolved and typos removed

This patch adds the adis16255 driver to the build system under the staging directory.
It solves also most issues mentioned in TODO list:
- sample rate exported to sysfs
- spi_adis16255_bringup and spi_adis16255_shutdown encapsulated
- chip selftest in spi_adis16255_bringup
- kernel messages reduced to a reasonable number
I removed the TODO file, because ther was only the reset of the gyroscope left.
This is IMOH not necessary for the actual driver.

There are also some typos in adis.c file. This patch should get rid of them as well.

From 9bf10920a094d71cec1076d3fa941aa6f31b09eb Mon Sep 17 00:00:00 2001
From: Lars Lindley <lindley@coyote.org>
Date: Sat, 8 May 2010 14:53:54 +0200
Subject: staging: winbond: localpara.h whitespace and indentation fixes.

I fixed all problems found by checkpatch.pl except a number of long
lines that I didn't find a good way to break up and still keep it
readable. I added the () to #define MAX_IE_APPEND_SIZE	(256 + 4).
I also moved som comments around after pointers from Pekka.

Subject: staging: rtl8192x: sync the various rtl819x_TSProc.c files

The rtl8192e, rtl8192su, and rtl8192u drivers all share what appears
to be a common private ieee80211 stack.  Various patches have been
applied to the rtl819x_TSProc.c file for some of the drivers but not
the others.

This sync's the files based on all the applied patches.

Subject: staging: rtl8192x: sync the various rtl819x_Qos.h files

The rtl8192e, rtl8192su, and rtl8192u drivers all share what appears
to be a common private ieee80211 stack.  Various patches have been
applied to the rtl819x_Qos.h file for some of the drivers but not the
others.

This sync's the files based on all the applied patches.

Subject: Staging: dt3155v4l: correcting a bug

dt3155v4l driver, as in -rc6-next-20100506 has a BUG.
When it modifies q->int_ops structure in videobuf-dma-contig
module the change is visible for all other modules using it.

Make a local copy of this structure and use its modification
to solve the bug.

Subject: md: set mddev readonly flag on blkdev BLKROSET ioctl

When the user sets the block device to readwrite then the mddev should
follow suit.  Otherwise, the BUG_ON in md_write_start() will be set to
trigger.

The reverse direction, setting mddev->ro to match a set readonly
request, can be ignored because the blkdev level readonly flag precludes
the need to have mddev->ro set correctly.  Nevermind the fact that
setting mddev->ro to 1 may fail if the array is in use.

Subject: Staging: wlags49: build fixes

Now that the code actually gets selected in the kernel config
properly, all of the build errors start showing up.

This patch papers over a few of them to get the code to build, I have
no idea if it actually works now or not...

Subject: staging: vt6655: Fix kernel BUG on driver wpa initialization

In http://bugzilla.novell.com/show_bug.cgi?id=597299, the vt6655 driver
generates a kernel BUG on a NULL pointer dereference at NULL. This problem
has been traced to a failure in the wpa_set_wpadev() routine. As the vt6656
driver does not call this routine, the vt6655 code is similarly set to skip
the call.

Subject: ACPICA: simplify SCI_EN workaround

acpi_hw_set_mode() double checks its effectiveness
by calling acpi_hw_get_mode() -- polling up to 3 seconds.

It would be more logical for its caller, acpi_enable()
acpi_enable() to do the double-checking.  (lets assume
that acpi_disable() isn't interesting)

The ACPI specification is unclear on this point.
Some parts say that the BIOS sets SCI_EN and then returns to the OS,
but one part says "OSPM polls the SCI_EN bit until it is sampled SET".

The systems I have on hand do the former,
SCI_EN is observed to be set upon return from the BIOS.

So we move the check up out of acpi_hw_set_mode()
up into acpi_enable() where it makes logical sense.

Then we replace the 3-second polling loop
with a single check.  If this check fails, we'll see:

	"Hardware did not enter ACPI mode"

and the system will bail out of ACPI initialization
and likely fail to boot.  If we see that in practice,
we can restore the polling, but put it into acpi_enable.

This patch is important if acpi_enable() is used in
the resume from S3 path.  Many systems today are seen
coming back from S3 with SCI_EN off, and then failing
to set SCI_EN in response to acpi_enable().  Those systems
will take 3 seconds longer to resume due to this loop.

However, it is possible that we will not use acpi_enable()
in the S3 resume path, and bang SCI_EN directly, which
would make the loop harmless, as it would be invisible
to all systems except those that need it.

Subject: ACPI: Unconditionally set SCI_EN on resume

The ACPI spec tells us that the firmware will reenable SCI_EN on resume.
Reality disagrees in some cases. The ACPI spec tells us that the only way
to set SCI_EN is via an SMM call.
https://bugzilla.kernel.org/show_bug.cgi?id=13745 shows us that doing so
may break machines. Tracing the ACPI calls made by Windows shows that it
unconditionally sets SCI_EN on resume with a direct register write, and
therefore the overwhelming probability is that everything is fine with
this behaviour.

Subject: crypto: mv_cesa - Use resource_size

Use the resource_size function instead of manually calculating the
resource size. This reduces the chance of introducing off-by-one errors.

Subject: staging: batman: remove all rcu head initializations

Remove all rcu head inits. We don't care about the RCU head state before
passing it to call_rcu() anyway. Only leave the "on_stack" variants so
debugobjects can keep track of objects on stack.

From 97a0638218fc504d645c45ff03256dc4520efa72 Mon Sep 17 00:00:00 2001
From: Nitin Gupta <ngupta@vflare.org>

Subject: Staging: ramzswap: Remove backing swap support

Currently, each ramzswap device can be assigned
a separate 'backing swap' file/partition. The ramzswap
driver forwards swap I/O requests to this backing swap
whenever an incompressible page is found.

This feature adds nearly 700 lines of code and it
also duplicates much of the swapon() functionality
(for example, finding swap extents and so on). Removing
this code makes the driver much simpler and should
help its transition from staging to stable drivers
area (drivers/block/).

Similar functionality may be implemented if we can
implement migrating pages across swap devices but the
details have not yet been worked out.

Support for _partitions_ as backing swap could be
retained as it requires a few lines of code only.
This part can be re-introduced later if above swap
migration method turns out to be infeasible.

More cleanups and code comments will be added soon.

From: Henk de Groot <henk.de.groot@hetnet.nl>
Date: Thu, 13 May 2010 16:27:33 +0200
Subject: Staging: wlags49_hs2: Fix wlags49_hs2 driver after build fixes broke
 it

Fixes the driver after merge into the 2.6.34 kernel. Driver should
be functional again (a fix to make it compile broke the driver).

Patch against 2.6.34 RC7 with patch-v2.6.34-rc7-next-20100513
already applied.

Removed conditional code based on kernel version, this is pointless
now the driver is part of the kernel. Also removed obsolte code
left over from previous patches. Includes also small fixes to compile
clean again.

Subject: Staging: dt3155v4l: introduce state machine

This patch introduces a v4l2 state machine, so now
CONFIG_DT3155_STREAMING is no more needed.

Use kcalloc or kzalloc rather than the combination of kmalloc and memset.

Subject: thinkpad-acpi: constrain IBM-era support to IBM boxes

Lenovo is playing around with its ACPI BIOS, and will end up reusing
method names.  Their memory is not nearly as long as thinkpad-acpi's...

Secure most of the old IBM codepaths against running in a non-IBM box.
This would happen on the Lenovo X100e in video_init(), for example.  We
would misdetect it as an ancient model 570 firmware.

Also, refuse to load the driver if we cannot identify the vendor.  No
ACPI ThinkPad in existence lacks this information, AFAIK.

The X100e needs some quick fixes to work semi-right with this driver.
There are much better ways to do this, but we can start with a quick
update and do it properly later.

Subject: thinkpad-acpi: fix volume/mute hotkey poll handling

The hotkey polling code is supposed to generate hotkey messages as
close to the way the IBM event-based volume hotkey firmware does as
possible, i.e:

* Pressing MUTE issues a mute hotkey event, even if already mute;

* Pressing Volume up/down issues a volume up/down hotkey event,
  even if already at maximum or minumum volume;

* The act of unmuting issues a volume up/down event, depending on
  which hotkey was used to unmute.

Fix the code to do just that (mute handling was incorrect), and handle
multiple hotkey presses between two polling cycles.

The new code uses the volume_toggle bit in NVRAM only to detect
repeated presses of the mute key and multiple presses of the volume
keys trying to go past the end of the volume scale.  This will work
around a bug in recent Lenovo firmware (e.g. T400), which causes the
firmware to not update the volume_toggle bit in certain situations.

Move the driver initial greetings out of the first subdriver, as we do a
lot of other initialization before that point, and the initial greetings
should go as soon as the driver decides that it should load.

These greetings are not cosmetic, they make my life easier when users
report bugs.

Subject: thinkpad-acpi: let other subdrivers know backlight level range

Extract the backlight level range size detection from the brightness
subdriver, and allow the other subdrivers access to that information.

This also allows us to relocate some code to a more convenient place.
The moved code was largerly unmodified, except for the return type of
tpacpi_check_std_acpi_brightness_support(), which now is correctly
marked as returning "unsigned int", and and two cosmetic fixes to make
checkpatch.pl happy.

Fixes for the NVRAM polling mode for the brightness hotkeys will need
this.

Subject: thinkpad-acpi: acpi_evalf fixes

Use acpi_format_exception() in acpi_evalf() instead of logging numeric
errors.

Also, when ACPICA returns an error, we should not be touching the return
object, as it is invalid.  In debug mode, acpi_evalf() callers would
printk the returned crap (but fortunately, not use it).

Subject: thinkpad-acpi: don't depend on led_path for led firmware type (v2)

Don't depend on the contents of led_path to know which LED interface
the firmware wants.

This removes the only user of *_path for the thinkpad-acpi ACPI
handlers, which will simplify future code.

Subject: thinkpad-acpi: clean up ACPI handles handling

1. Remove <handle>_path, as its only user was already removed in
   a previous commit

2. Move all handle initialization, as well as <handle>_parent and
   <handle>_paths to __init.* sections.  This reduces the driver's
   runtime footprint nicely.

Subject: drivers: Push down BKL into various drivers

These are the last remaining device drivers using
the ->ioctl file operation in the drivers directory
(except from v4l drivers).

[fweisbec: drop i8k pushdown as it has been done from
procfs pushdown branch already]

Subject: md/linear: avoid possible oops and array stop

Since commit ef286f6fa673cd7fb367e1b145069d8dbfcc6081
it has been important that each personality clears
->private in the ->stop() function, or sets it to a
attribute group to be removed.
linear.c doesn't.  This can sometimes lead to an oops,
though it doesn't always.

Suitable for 2.6.33-stable and 2.6.34.

Subject: md: remove unneeded sysfs files more promptly

When an array is stopped we need to remove some
sysfs files which are dependent on the type of array.

We need to delay that deletion as deleting them while holding
reconfig_mutex can lead to deadlocks.

We currently delay them until the array is completely destroyed.
However it is possible to deactivate and then reactivate the array.
It is also possible to need to remove sysfs files when changing level,
which can potentially happen several times before an array is
destroyed.

So we need to delete these files more promptly: as soon as
reconfig_mutex is dropped.

We need to ensure this happens before do_md_run can restart the array,
so we use open_mutex for some extra locking.  This is not deadlock
prone.

Subject: md: manage redundancy group in sysfs when changing level.

Some levels expect the 'redundancy group' to be present,
others don't.
So when we change level of an array we might need to
add or remove this group.

This requires fixing up the current practice of overloading ->private
to indicate (when ->pers == NULL) that something needs to be removed.
So create a new ->to_remove to fill that role.

When changing levels, we may need to add or remove attributes.  When
changing RAID5 -> RAID6, we both add and remove the same thing.  It is
important to catch this and optimise it out as the removal is delayed
until a lock is released, so trying to add immediately would cause
problems.

Subject: intel-iommu: errors with smaller iommu widths

When using iommu_domain_alloc with the Intel iommu, the domain address
width is always initialized to 48 bits (agaw 2).  This domain->agaw value
is then used by pfn_to_dma_pte to (always) build a 4 level page table.
However, not all systems support iommu width of 48 or 4 level page tables.
In particular, the Core i5-660 and i5-670 support an address width of 36
bits (not 39!), an agaw of only 1, and only 3 level page tables.

This version of the patch simply lops off extra levels of the page tables
if the agaw value of the iommu is less than what is currently allocated
for the domain (in intel_iommu_attach_device).  If there were already
allocated addresses above what the new iommu can handle, EFAULT is
returned.

Subject: DMA ENGINE: Do not reset 'private' of channel

The member 'private' of 'struct dma_chan' is meant for passing
data between client and the controller driver.

The DMA client driver may point it to platform specific stuff after
acquiring the channel. So, it is the responsiblity of the same code
to reset it, if it must.

The DMA engine doesn't set it and hence, shouldn't reset it either.

This reseting of private by DMA Engine comes in the way of implementing
default channel settings during DMAC probe. That capability is useful
for not having the clients to always provide platform specific data,
like Rx/Tx FIFO addresses, which usually doesn't change across channel
requests.

Subject: [PATCH] ARM: mx3: Fix a race condition in mxcmmc

This fixes a race condition regarding interrupt bits in the SDHC
controller driver code.

In case of PIO-transfer it does not clear SDHC-status bit#11/12
in the INT-handler anymore. INT-handler might be called during
an ongoing PIO-data-transfer (with some other INT-flag set) and
PIO-transfer depends on these bits being set to detect the end
of the data-transfer. This also means that at the end of PIO-
transfer that PIO-software has to clear these bits itself.

However in case of DMA-transfer these bits have to be cleared
in the INT-handler, because they are used to generate INTs then.

Works solid, no more problems here, can transfer big files.

Subject: classmate-laptop: Add RFKILL support.

The RFKILL device shares the same ACPI device used for backlight. So, it
required a new struct sharing both a backlight_device and a rfkill
device.

Subject: drbd: Do not upgrade state to Outdated if already Inconsistent [Bugz
 277]

There was a race condition:
  In a situation with a SyncSource+Primary and a SyncTarget+Secondary node,
  and a resync dependency to some other device. After both nodes decided
  to do the resync, the other device finishes its resync process.
  At that time SyncSource already sent the P_SYNC_UUID packet, and
  already updated its peer disk state to Inconsistent.
  The SyncTarget node waits for the P_SYNC_UUID and sends a state packet
  to report the resync dependency change. That packet still carries
  a disk state of Outdated.

Impact:
  If application writes come in, during that time on the Primary node,
  those do not get replicated, and the out-of-sync counter gets increased.
  => The completion of resync is not detected on the primary node.
  => stalled.
  Those blocks get resync'ed with the next resync, since the are get
  marked as out-of-sync in the bitmap.

In order to fix this, we filter out that wrong state change in the
sanitize_state() function.

Subject: drbd: don't start a resync without access to up-to-date Data

In case both nodes are "inconsistent", invalidate would
have started a resync anyways, without a chance to ever
succeed, just filling the logs with warning messages.

Simply disallow that state change,
re-using the SS_NO_UP_TO_DATE_DISK return value.

This also changes the corresponding error string to
"Need access to UpToDate Data" -- I found the
"Refusing to be Primary without at least one UpToDate disk"
answer misleading in some situations anyways.

Subject: drbd: check for corrupt or malicous sector addresses when receiving
 data

Even if it should never happen if the peer does behave, we need to
double check, and not even attempt access beyond end of device.
It usually would be caught by lower layers, resulting in "IO error",
but may also end up in the internal meta data area.

 optimization

The condition does not fit the commend (I may well be Primary,
even if I lost the disk earlier and now the connection).

And this is catched below anyways, where it also gets logged.

Some wish to be notified of all instances of split brain, not just those that
go unresolved.  The initial-split-brain handler is called to notify someone
upon  detection of all split brain conditions even if auto-recovery policies
are configured.

Subject: drbd: Fixed bitmap in case of online-grow without resync

The "surplus" bits of the old (smaller) bitmap must be clean
in case of online-grow without resync.

Note: Reverted 67ae8b80d4a116ab3b7094eb3723506b20c06dff as
well, since the lines added by this patch are redundant. The
bits get set by the bm_set_surplus(b) call before that.

Subject: drbd: Four new configuration settings for resync speed control

To reasonably control resync speed over drbd-proxy connections,
drbd has to measure the current delay of packets transmitted over
the (possibly congested) data socket vs the meta-data socket.

Subject: drbd: Control the actual resync rate based on the queuing delay of
 data packets

In a setup with a high bandwidth and high latency network, eventually
involving deep queues in routers, it is beneficial to only fill those
queues up to an limited extend with resync data.

Subject: drbd: A fixes to the new resync speed code

* Mention P_DELAY_PROBE in the packet naming array
* Do not corrupt the mdev->data.work list in case the timer goes
  off before delay_probe_work got handled by the worker
* Do not mod_timer() twice for a single delay_probe pair

Subject: Staging: vt6655: use ETH_HLEN macro instead of custom one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaced custom header length definition U_HEADER_LEN by ETH_HLEN
from <linux/if_ether.h>. Also remove unused U_TYPE_LEN.

Subject: drbd: Fixes to the new delay_probes code

* Only send delay_probes with protocol 93 or newer
* drbd_send_delay_probes() is called only from worker context,
  no atomic_t needed for delay_seq

Subject: DMAENGINE: extend the control command to include an arg

This adds an argument to the DMAengine control function, so that
we can later provide control commands that need some external data
passed in through an argument akin to the ioctl() operation
prototype.

Subject: Staging: Use kmemdup

Use kmemdup when some other buffer is immediately copied into the
allocated region.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression from,to,size,flag;
statement S;
@@

-  to = \(kmalloc\|kzalloc\)(size,flag);
+  to = kmemdup(from,size,flag);
   if (to==NULL || ...) S
-  memcpy(to, from, size);
// </smpl>

Subject: Staging: wlan-ng prism2usb: add suspend/resume

There is no need trying to load the (even in most cases) not availible
firmware after suspend. This saves about 30 secounds on reset waiting
for timeout.

Subject: drbd: always use_bmbv, ignore setting

Now that the peer may handle multi-bio EEs,
we can ignore the peer's limit,
and concentrate on the limits of the local IO stack.

This is safe accross drbd protocol versions,
as our queue_max_sectors() will be adjusted accordingly.

Subject: drbd: If we detect late that IO got frozen, retry after we thawed.

If we detect late (= after grabing mdev->req_lock) that IO got frozen, we
return 1 to generic_make_request(), which simply will retry to make a
request for that bio.

In the subsequent call of generic_make_request() into drbd_make_request_26()
we sleep in inc_ap_bio().

Subject: drbd: Create new current UUID as late as possible

The choice was to either delay creation of the new UUID until
IO got thawed or to delay it until the first IO request.

Both are correct, the later is more friendly to users of
dual-primary setups, that actually only write on one side.

Subject: md/raid1: fix counting of write targets.

There is a very small race window when writing to a
RAID1 such that if a device is marked faulty at exactly the wrong
time, the write-in-progress will not be sent to the device,
but the bitmap (if present) will be updated to say that
the write was sent.

Then if the device turned out to still be usable as was re-added
to the array, the bitmap-based-resync would skip resyncing that
block, possibly leading to corruption.  This would only be a problem
if no further writes were issued to that area of the device (i.e.
that bitmap chunk).

Suitable for any pending -stable kernel.

Keep track of the maximum number of concurrent write-behind requests

Writing any value to this file will clear it.

This allows userspace to be involved in tuning bitmap/backlog.

Subject: md: discard StateChanged device flag.

This was needed when sysfs files could only be 'notified'
from process context.  Now that we have sys_notify_direct,
we can call it directly from an interrupt.

From 84707f38e767ac470fd82af6c45a8cafe2bd1b9a Mon Sep 17 00:00:00 2001
From: NeilBrown <neilb@suse.de>
Date: Tue, 16 Mar 2010 17:23:35 +1100
Subject: md: don't use mddev->raid_disks in raid0 or raid10 while array is
 active.

In a subsequent patch we will make it possible to change
mddev->raid_disks while a RAID0 or RAID10 array is active.  This is
part of the process of reshaping such an array.

This means that we cannot use this value while processes requests
(it is OK to use it during initialisation as we are locked against
changes then).
Both RAID0 and RAID10 have the same value stored in the private data
structure, so use that value instead.

Subject: md: Correctly handle device removal via sysfs

Writing "none" to "../md/dev-xx/slot" removes that device
from being an active part of the array, but it didn't
set ->raid_disk to -1 to record this fact.

When metadata is being managed by user-space, md doesn't know
what the maximum number of devices allowed in an array is
so ->max_disks is 0.  In this case we should allow any (+ve)
number of disks.

Subject: md: move io accounting out of personalities into md_make_request

While I generally prefer letting personalities do as much as possible,
given that we have a central md_make_request anyway we may as well use
it to simplify code.
Also this centralises knowledge of ->gendisk which will help later.

Subject: md: remove ->changed and related code.

We set ->changed to 1 and call check_disk_change at the end
of md_open so that bd_invalidated would be set and thus
partition rescan would happen appropriately.

Now that we call revalidate_disk directly, which sets bd_invalidates,
that indirection is no longer needed and can be removed.

Subject: md: factor do_md_run to separate accesses to ->gendisk

As part of relaxing the binding between an mddev and gendisk,
we separate do_md_run into two functions.
  md_run does all the work internal to md
  do_md_run calls md_run and makes and changes to gendisk
     that are required.

do_md_stop is large and clunky, so hard to understand.

This is a first step of refactoring, pulling two simple
sub-functions out.

Subject: md: factor md_stop_writes out of do_md_stop.

Further refactoring of do_md_stop.
This one requires some explanation as it takes code from different
places in do_md_stop, so some re-ordering happens.

We only get into this part of do_md_stop if there are no active opens
of the device, so no writes can be happening and the device must have
been flushed.  In md_stop_writes we want to stop any internal sources
of writes - i.e. resync - and flush out the metadata.

The only code that was previously before some of this code is
code to clean up the queue, the mddev, the gendisk, or sysfs, all
of which is probably better after code that makes active changes (i.e.
triggers writes).

Subject: md: split md_set_readonly out of do_md_stop

Using do_md_stop to set an array to read-only is a little confusing.
Now most of the common code has been factored out, split
md_set_readonly off in to a separate function.

Subject: md: call md_stop_writes from md_stop

This moves the call to the other side of set_readonly, but that should
not be an issue.
This encapsulates in 'md_stop' all of the functionality for internally
stopping the array, leaving all the interactions with externalities
(sysfs, request_queue, gendisk) in do_md_stop.

Subject: md: pass mddev to make_request functions rather than request_queue

We used to pass the personality make_request function direct
to the block layer so the first argument had to be a queue.
But now we have the intermediary md_make_request so it makes
at lot more sense to pass a struct mddev_s.
It makes it possible to have an mddev without its own queue too.

Subject: md: don't unregister the thread in mddev_suspend

This is
 - unnecessary because mddev_suspend is always followed by a call to
   ->stop, and each ->stop unregisters the thread, and
 - a problem as it makes it awkwards to suspend and then resume a
   device as we will want later.

This message seems to suggest the named device is the one on which a
read failed, however it is actually the device that the read will be
redirected to.
So make the message a little clearer.

Subject: md/raid1: delay reads that could overtake behind-writes.

When a raid1 array is configured to support write-behind
on some devices, it normally only reads from other devices.
If all devices are write-behind (because the rest have failed)
it is possible for a read request to be serviced before a
behind-write request, which would appear as data corruption.

So when forced to read from a WriteMostly device, wait for any
write-behind to complete, and don't start any more behind-writes.

Subject: md/raid5: improve consistency of error messages.

Many 'printk' messages from the raid456 module mention 'raid5' even
though it may be a 'raid6' or even 'raid4' array.  This can cause
confusion.
Also the actual array name is not always reported and when it is
it is not reported consistently.

So change all the messages to start:
    md/raid:%s:
where '%s' becomes e.g. md3 to identify the particular array.

Subject: md: Fix read balancing in RAID1 and RAID10 on drives > 2TB

read_balance uses a "unsigned long" for a sector number which
will get truncated beyond 2TB.
This will cause read-balancing to be non-optimal, and can cause
data to be read from the 'wrong' branch during a resync.  This has a
very small chance of returning wrong data.

Subject: md: restore ability of spare drives to spin down.

Some time ago we stopped the clean/active metadata updates
from being written to a 'spare' device in most cases so that
it could spin down and say spun down.  Device failure/removal
etc are still recorded on spares.

However commit 51d5668cb2e3fd1827a55 broke this 50% of the time,
depending on whether the event count is even or odd.
The change log entry said:

   This means that the alignment between 'odd/even' and
    'clean/dirty' might take a little longer to attain,

how ever the code makes no attempt to create that alignment, so it
could take arbitrarily long.

So when we find that clean/dirty is not aligned with odd/even,
force a second metadata-update immediately.  There are already cases
where a second metadata-update is needed immediately (e.g. when a
device fails during the metadata update).  We just piggy-back on that.

Fix: Raid-6 was not trying to correct a read-error when in

doubly-degraded state. This patch fixes this behaviour.

Subject: md: simplify updating of event count to sometimes avoid updating
 spares.

When updating the event count for a simple clean <-> dirty transition,
we try to avoid updating the spares so they can safely spin-down.
As the event_counts across an array must be +/- 1, this means
decrementing the event_count on a dirty->clean transition.
This is not always safe and we have to avoid the unsafe time.
We current do this with a misguided idea about it being safe or
not depending on whether the event_count is odd or even.  This
approach only works reliably in a few common instances, but easily
falls down.

So instead, simply keep internal state concerning whether it is safe
or not, and always assume it is not safe when an array is first
assembled.

Subject: md: don't insist on valid event count for spare devices.

Devices which know that they are spares do not really need to have
an event count that matches the rest of the array, so there are no
data-in-sync issues. It is enough that the uuid matches.
So remove the requirement that the event count is up-to-date.

We currently still write out and event count on spares, but this
allows us in a year or 3 to stop doing that completely.

Subject: OMAP: DSS2: fix lock_fb_info() and omapfb_lock() locking order

Framebuffer ioctl processing forces lock_fb_info() -> omapfb_lock()
locking order. Follow that order to avoid possible circular locking
dependency, detected by lockdep.

Subject: OMAP: DSS2: Make partial update width even
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are some strange problems with DSI and updates with odd widths. One
particular problem is that HS TX timeout triggers easily with updates with
odd widths.

This patch makes the updates widths even, circumventing the problem. There
should be no ill side effects with increasing the update area slightly to
make the width even.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If omapdss_dsi_display_enable() failed the DSI bus was left locked. Also
if the operation failed later omapdss_dsi_display_disable() would get
called without holding the bus lock.

From ac01bb7ea06a02c8dc9084b4ed59cb59efeceb39 Mon Sep 17 00:00:00 2001
From: Kishore Y <kishore.y@ti.com>
Date: Sun, 25 Apr 2010 16:27:19 +0530
Subject: OMAP3630: DSS2: Updating MAX divider value

In DPLL4 M3, M4, M5 and M6 field width has been increased by 1 bit in 3630.
So the max divider value that can be achived will be 32 and not 16.
In 3630 the functional clock is x1 of DPLL4 and not x2. Hence multiplier 2
is removed.

Subject: OMAP2: DSS: Add missing line for update bg color

The driver set the background color canvas but never writes it in
DISPC_DEFAULT_COLOR_m register, which changes the background color
on the LCD or TV.

This patch adds a line to call to dispc_set_default_color() which is
the function in charge to write the DISPC_DEFAULT_COLOR_m register.

Move a number of #ifdefs from code into dss.h and elsewhere, and
conditionally define no-op static inline functions, cleaning up the
code. This style is according to Documentation/SubmittingPatches.

Subject: Always call i7core_[ur]dimm_check_mc_ecc_err

This fixes an error in function i7core_check_error

In commit ca9c90ba09ca3c9799319f46a56f397afbf617c2 which converts the
driver to use double buffering, there is a change in the logic.  Before,
if mce_count was zero, it skipped over a couple of statements and
finished out with a call to the *check_mc_ecc_err function.  The current
code checks to see if mce_count is 0 and then exits.

This change reverts the behavior back to the original where if there are
no errors to report, we skip to the end and call the *check_mc_ecc_err
function.

This fix allows the driver to work again on my Nehalem based blades
again.

Subject: i7core_edac: Add support for X5670

As reported by Vernon Mauery <vernux@us.ibm.com>, X5670 (Westmere-EP) uses a
different register for one of the uncore PCI devices. Add support for
it.

Those are the PCI ID's on this new chipset:

fe:00.0 0600: 8086:2c70 (rev 02)
fe:00.1 0600: 8086:2d81 (rev 02)
fe:02.0 0600: 8086:2d90 (rev 02)
fe:02.1 0600: 8086:2d91 (rev 02)
fe:02.2 0600: 8086:2d92 (rev 02)
fe:02.3 0600: 8086:2d93 (rev 02)
fe:02.4 0600: 8086:2d94 (rev 02)
fe:02.5 0600: 8086:2d95 (rev 02)
fe:03.0 0600: 8086:2d98 (rev 02)
fe:03.1 0600: 8086:2d99 (rev 02)
fe:03.2 0600: 8086:2d9a (rev 02)
fe:03.4 0600: 8086:2d9c (rev 02)
fe:04.0 0600: 8086:2da0 (rev 02)
fe:04.1 0600: 8086:2da1 (rev 02)
fe:04.2 0600: 8086:2da2 (rev 02)
fe:04.3 0600: 8086:2da3 (rev 02)
fe:05.0 0600: 8086:2da8 (rev 02)
fe:05.1 0600: 8086:2da9 (rev 02)
fe:05.2 0600: 8086:2daa (rev 02)
fe:05.3 0600: 8086:2dab (rev 02)
fe:06.0 0600: 8086:2db0 (rev 02)
fe:06.1 0600: 8086:2db1 (rev 02)
fe:06.2 0600: 8086:2db2 (rev 02)
fe:06.3 0600: 8086:2db3 (rev 02)
(as usual, the same PCI devices repeat at ff: bus)

The PCI device 8086:2c70 is shown as:

fe:00.0 Host bridge: Intel Corporation QuickPath Architecture Generic
Non-core Registers (rev 02)

So, for this device to be recognized, it is only a matter of adding this
new PCI ID to the driver.

Subject: Staging: comedi: new Kconfig and Makefiles, drivers grouped by
 bustype.

PC/104-drivers went into ISA,
PC/104+ went into PCI,
Drivers without a bustype went into "misc".
In doubt drivers supporting both ISA/PCI went into PCI.
Drivers without any detailed hardware info went into ISA, e.g. fl512.c
Some NI drivers are used by other NI drivers from different bustypes
are grouped seperately in NI_COMMON.

[tweaked by gregkh to handle the new driver recently added]

Subject: Staging: comedi: fix up build error from last Kconfig changes

We need the 8255 module to be present for some PCI comedi
modules.  So for now, just build the thing.  We need some better
Kconfig rules to figure this out properly.

Subject: Staging: comedi: Kconfig dependancy fixes

There are three minor changes I would like to do on my last patch:

* Comedi is formally not dependant on any hardware, e.g. it is possible
  to use comedi_test without (PCI || PCMCIA || PCCARD || USB || ISA)
* comedi_parport is not dependant on PARPORT_PC.
* indirect ni_mio_cs (16-bit PCMCIA) dependancy on mite PCI-chip may
  confuse users, thus changing COMEDI_NI_TIO depends on COMEDI_MITE
  to select COMEDI_MITE.

Subject: PCI: Disable MSI for MCP55 on P5N32-E SLI

As reported in <http://bugs.debian.org/552299>, MSI appears to be
broken for this on-board device.  We already have a quirk for the
P5N32-SLI Premium; extend it to cover both variants of the board.

Subject: Staging: iio: max1363 Fix two bugs in single_channel_from_ring

This patch contains fixes for the two bugs Michael pointed
out last week.  As the other suggestion Michael made is
not a bug fix (just a much more sensible way of handling
things), I'll do that as a separate patch soon.

The bugs were introduced with the abi changes.

Subject: staging: iio: adis16350 and similar IMU driver

This version has the right part number in the commit message.
Whilst technically the part I listed last time is also supported
by the driver, the commit message might have caused confusion.

Another driver from Barry at Analog.  Again, I've lifted
if from the blackfin tree and done the usual sparse
and checkpatch fixes + the abi changes.  I actually
have one of these, so am particularly pleased to see
it supported!

Subject: Staging: comedi: Altered the way printk is used in 8255.c

This patch moves around the use of printk calls in 8255.c to include accurate
logging levels and in turn fixes a few warnings from checkpatch.

Subject: Staging: dt3155v4l: remove private memory allocator

This patch removes the private memory allocator
and all conjugated functions. Now the driver uses
videobuf-dma-contig module for allocations.
Added reserving 4MB coherent memory for private
per device allocations at probe time.

Subject: PCI: output FW warning in pci_read/write_vpd

pci_read/write_vpd() can fail due to a timeout.  Usually the command
times out because of firmware issues (incorrect vpd length, etc.) on the
PCI card.  Currently, the timeout occurs silently.

Output a message to the user indicating that they should check with
their vendor for new firmware.

Subject: firewire: core: Fix tlabel exhaustion problem

fw_core_handle_response() was not properly clearing tlabel_mask. This
was resulting in premature tlabel exhaustion.

Signed-off-by: Peter Hurley <phurley@charter.net>

This fixes an omission in 2.6.31-rc1 commit 1e626fdc "firewire: core:
use more outbound tlabels" which prevented to really use 64 instead of
32 transaction labels, as soon as split transactions occurred that had
their AR-resp tasklet run after the AT-req tasklet.

Subject: of: Always use 'struct device.of_node' to get device node pointer.

The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated.  This patch
makes all readers of these elements use device.of_node instead.

(struct of_device *)->node
(struct dev_archdata *)->prom_node (sparc)
(struct dev_archdata *)->of_node (powerpc & microblaze)

From 58f9b0b02414062eaff46716bc04b47d7e79add5 Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@secretlab.ca>
Date: Tue, 13 Apr 2010 16:12:56 -0700
Subject: of: eliminate of_device->node and dev_archdata->{of,prom}_node

This patch eliminates the node pointer from struct of_device and the
of_node (or prom_node) pointer from struct dev_archdata since the node
pointer is now part of struct device proper when CONFIG_OF is set, and
all users of the old pointer locations have already been converted over
to use device->of_node.

Also remove dev_archdata_{get,set}_node() as it is no longer used by
anything.

Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

From 5c40cbfefa828208c671e2f58789e4dd04f79563 Mon Sep 17 00:00:00 2001
From: Clemens Ladisch <clemens@ladisch.de>

Subject: firewire: core: use separate timeout for each transaction

Using a single timeout for all transaction that need to be flushed does
not work if the submission of new transactions can defer the timeout
indefinitely into the future.  We need to have timeouts that do not
change due to other transactions; the simplest way to do this is with a
separate timer for each transaction.

Subject: hisax_fcpcipnp: fix broken isapnp device table.

Found that drivers/isdn/hisax/hisax_fcpcipnp.c has broken pnp device table -
wrong type (isapnp instead of pnp) and also ending record missing.

Subject: power_supply: Use attribute groups

This fixes a race between power supply device and initial
attributes creation, plus makes it possible to implement
writable properties.

[Daniel Mack - removed superflous return statement
 and dropped .mode attribute from POWER_SUPPLY_ATTR]

Subject: power_supply: Add support for writeable properties

This patch adds support for writeable power supply properties and
exposes them as writeable to sysfs.

A power supply implementation must implement two new function calls in
order to use that feature:

  int set_property(struct power_supply *psy,
                   enum power_supply_property psp,
                   const union power_supply_propval *val);

  int property_is_writeable(struct power_supply *psy,
                            enum power_supply_property psp);

Subject: ds2760_battery: Make charge_now and charge_full writeable

For userspace tools and daemons, it might be necessary to adjust
the charge_now and charge_full properties of the ds2760 battery monitor,
for example for unavoidable corrections due to aging batteries.

Subject: crypto: talitos - prepare for adding ahash algorithms

No functional changes.
Use a union in talitos_alg_template for the crypto_alg
so that we can add a member later for ahash_alg.

Subject: crypto: talitos - second prepare step for adding ahash algorithms

Used talitos_alg_template in talitos_crypto_alg
so that it will accommodate ahash algorithms.
Added some preparation code for ahash allocation and removal.
No actual algorithms yet.

From 60f208d7836216885cdcd6f77a02f31dbc66f169 Mon Sep 17 00:00:00 2001
From: Kim Phillips <kim.phillips@freescale.com>
Date: Wed, 19 May 2010 19:21:53 +1000
Subject: crypto: talitos - add support for sha224

SEC h/w versions 2.1 and above support sha224 via explicit instruction.

Performing sha224 ahashes on earlier versions is still possible because
they support sha256 (sha224 is sha256 with different initial constants
and a different truncation length).  We do this by overriding hardware
context self-initialization, and perform it manually in s/w instead.

Thanks to Lee for his fixes for correct execution on actual sec2.0 h/w.

Subject: virtio_ring: remove a level of indirection

We have a single virtqueue_ops implementation,
and it seems unlikely we'll get another one
at this point. So let's remove an unnecessary
level of indirection: it would be very easy to
re-add it if another implementation surfaces.

Subject: virtio: Revert "virtio: disable multiport console support."

This reverts commit b7a413015d2986edf020fba765c906cc9cbcbfc9.

Multiport support was disabled for 2.6.34 because we wanted to introduce
a new ABI and since we didn't have any released kernel with the older
ABI and were out of the merge window, it didn't make sense keeping the
older ABI around.

Now we revert the patch disabling multiport and rework the ABI in the
following patches.

We will introduce control messages that operate on the device as a whole
rather than just ports. Make send_control_msg() a wrapper around
__send_control_msg() which does not need a valid port.

Subject: virtio: console: Don't call hvc_remove() on unplugging console ports

hvc_remove() has some bug which freezes other active hvc ports when one
port is removed.

So disable calling of hvc_remove() which deregisters a port with the
hvc_console.

If the hvc_console code calls into our get_chars() routine as a result
of a poll operation, we will return -EPIPE and the hvc_console code will
then do the necessary cleanup.

This call will be restored when the bug in hvc_remove() is found and
fixed.

Subject: virtio: console: Move code around for future patches

We're going to use add_port() from handle_control_message() in the next
patch.

Move the add_port() and fill_queue(), which depends on it, above
handle_control_message() to avoid forward declarations.

Subject: virtio: console: Use a control message to add ports

Instead of the host and guest independently enumerating ports, switch to
a control message to add ports where the host supplies the port number
so there's no ambiguity or a possibility of a race between the host and
the guest port numbers.

We now no longer need the 'nr_ports' config value. Since no kernel has
been released with the MULTIPORT changes yet, we have a chance to fiddle
with the config space without adding compatibility features.

This is beneficial for management software, which would now be able to
instantiate ports at known locations and avoid problems that arise with
implicit numbering in the host and the guest. This removes the 'guessing
game' part of it, and management software can now actually indicate
which id to spawn a particular port on.

If we're using multiport, there's no point in always creating a console

We'll introduce a function that checks if write will block.  Have
function names that are similar for the two cases.

Subject: virtio: console: Add support for nonblocking write()s

If the host port is not open, a write() should either just return if the
file is opened in non-blocking mode, or block till the host port is
opened.

Also, don't spin till host consumes data for nonblocking ports. For
non-blocking ports, we can do away with the spinning and reclaim the
buffers consumed by the host on the next write call or on the condition
that'll make poll return.

Subject: virtio: console: Store each console's size in the console structure

With support for multiple consoles, just using one {rows,cols} pair in
the config space is not going to suffice.

Store each console's size as part of the console struct.

This changes the behaviour for one case when multiport is not enabled:
when notifier_add_vio() is called, the console size is taken from that
of the last config-space update instead of fetching it afresh from the
config space.

Also add a helper to update the size in the console struct as we'll need
to use the same code to update the size via control messages when
multiport support is enabled.

Subject: drivers/char: Eliminate use after free

In each case, the first argument to send_control_msg or __send_control_msg,
respectively, has either not been successfully allocated or has been freed
at the point of the call.  In the first case, the first argument, port, is
only used to access the portdev and id fields, in order to call
__send_control_msg.  Thus it seems possible instead to call
__send_control_msg directly.  In the second case, the call to
__send_control_msg is moved up to a place where it seems like the first
argument, portdev, has been initialized sufficiently to make the call to
__send_control_msg meaningful.

This has only been compile tested.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

Subject: ACPI, IO memory pre-mapping and atomic accessing

Some ACPI IO accessing need to be done in atomic context. For example,
APEI ERST operations may be used for permanent storage in hardware
error handler. That is, it may be called in atomic contexts such as
IRQ or NMI, etc. And, ERST/EINJ implement their operations via IO
memory/port accessing.  But the IO memory accessing method provided by
ACPI (acpi_read/acpi_write) maps the IO memory during it is accessed,
so it can not be used in atomic context. To solve the issue, the IO
memory should be pre-mapped during EINJ/ERST initializing. A linked
list is used to record which memory area has been mapped, when memory
is accessed in hardware error handler, search the linked list for the
mapped virtual address from the given physical address.

From a643ce207f3e70030bdb431e2a363cc111a60c1a Mon Sep 17 00:00:00 2001
From: Huang Ying <ying.huang@intel.com>
Date: Tue, 18 May 2010 14:35:12 +0800
Subject: ACPI, APEI, APEI supporting infrastructure

APEI stands for ACPI Platform Error Interface, which allows to report
errors (for example from the chipset) to the operating system. This
improves NMI handling especially. In addition it supports error
serialization and error injection.

For more information about APEI, please refer to ACPI Specification
version 4.0, chapter 17.

This patch provides some common functions used by more than one APEI
tables, mainly framework of interpreter for EINJ and ERST.

A machine readable language is defined for EINJ and ERST for OS to
execute, and so to drive the firmware to fulfill the corresponding
functions. The machine language for EINJ and ERST is compatible, so a
common framework is defined for them.

From 9dc966641677795f4d6b0a9ba630d6a3a3e24a57 Mon Sep 17 00:00:00 2001
From: Huang Ying <ying.huang@intel.com>
Date: Tue, 18 May 2010 14:35:13 +0800
Subject: ACPI, APEI, HEST table parsing

HEST describes error sources in detail; communicating operational
parameters (i.e. severity levels, masking bits, and threshold values)
to OS as necessary. It also allows the platform to report error
sources for which OS would typically not implement support (for
example, chipset-specific error registers).

HEST information may be needed by other subsystems. For example, HEST
PCIE AER error source information describes whether a PCIE root port
works in "firmware first" mode, this is needed by general PCIE AER
error subsystem. So a public HEST tabling parsing interface is
provided.

From affb72c3a8984ba55e055b0a0228c3ea1a056758 Mon Sep 17 00:00:00 2001
From: Huang Ying <ying.huang@intel.com>

Subject: ACPI, APEI, PCIE AER, use general HEST table parsing in AER
 firmware_first setup

Now, a dedicated HEST tabling parsing code is used for PCIE AER
firmware_first setup. It is rebased on general HEST tabling parsing
code of APEI. The firmware_first setup code is moved from PCI core to
AER driver too, because it is only AER related.

Subject: ACPI Hardware Error Device (PNP0C33) support

Hardware Error Device (PNP0C33) is used to report some hardware errors
notified via SCI, mainly the corrected errors. Some APEI Generic
Hardware Error Source (GHES) may use SCI on hardware error device to
notify hardware error to kernel.

After receiving notification from ACPI core, it is forwarded to all
listeners via a notifier chain. The listener such as APEI GHES should
check corresponding error source for new events when notified.

From 06d65deade9aabba58e0518df86dcd324e86b832 Mon Sep 17 00:00:00 2001
From: Huang Ying <ying.huang@intel.com>
Date: Tue, 18 May 2010 14:35:19 +0800
Subject: ACPI, APEI, UEFI Common Platform Error Record (CPER) header

CPER stands for Common Platform Error Record, it is the hardware error
record format used to describe platform hardware error by various APEI
tables, such as ERST, BERT and HEST etc.

For more information about CPER, please refer to Appendix N of UEFI
Specification version 2.3.

This patch mainly includes the data structure difinition header file
used by other files.

Subject: ACPI, APEI, Generic Hardware Error Source memory error support

Generic Hardware Error Source provides a way to report platform
hardware errors (such as that from chipset). It works in so called
"Firmware First" mode, that is, hardware errors are reported to
firmware firstly, then reported to Linux by firmware. This way, some
non-standard hardware error registers or non-standard hardware link
can be checked by firmware to produce more valuable hardware error
information for Linux.

Now, only SCI notification type and memory errors are supported. More
notification type and hardware error type will be added later. These
memory errors are reported to user space through /dev/mcelog via
faking a corrected Machine Check, so that the error memory page can be
offlined by /sbin/mcelog if the error count for one page is beyond the
threshold.

On some machines, Machine Check can not report physical address for
some corrected memory errors, but GHES can do that. So this simplified
GHES is implemented firstly.

From a08f82d08053fb6e3aa3635c2c26456d96337c8b Mon Sep 17 00:00:00 2001
From: Huang Ying <ying.huang@intel.com>
Date: Tue, 18 May 2010 14:35:21 +0800
Subject: ACPI, APEI, Error Record Serialization Table (ERST) support

ERST is a way provided by APEI to save and retrieve hardware error
record to and from some simple persistent storage (such as flash).

The Linux kernel support implementation is quite simple and workable
in NMI context. So it can be used to save hardware error record into
flash in hardware error exception or NMI handler, where other more
complex persistent storage such as disk is not usable. After saving
hardware error records via ERST in hardware error exception or NMI
handler, the error records can be retrieved and logged into disk or
network after a clean reboot.

For more information about ERST, please refer to ACPI Specification
version 4.0, section 17.4.

This patch incorporate fixes from Jin Dongming.

Subject: ACPI, APEI, EINJ injection parameters support

Some hardware error injection needs parameters, for example, it is
useful to specify memory address and memory address mask for memory
errors.

Some BIOSes allow parameters to be specified via an unpublished
extension. This patch adds support to it. The parameters will be
ignored on machines without necessary BIOS support.

ACPI: WMI: DEBUG Event INTEGER_TYPE - 65535

Situation where a driver registers for specific event and debug
handler gets overridden and set again if the registering driver gets
unloaded again is untested, but should work.

Subject: wimax/i2400m: fix bad race condition check in RX path

The i2400m->rx_roq data structure is protected against race conditions
with a reference count (i2400m->rx_roq_refcount); the pointer can be
read-referenced under the i2400m->rx_lock spinlock.

The code in i2400m_rx_edata() wasn't properly following access
protocol, performing an invalid check on i2400m->rx_roq (which is
cleared to NULL when the refcount drops to zero). As such, it was
missing to detect when the data structure is no longer valid and
oopsing with a NULL pointer dereference.

This commit fixes said check by verifying, under the rx_lock spinlock,
that i2400m->rx_roq is non-NULL and then increasing the reference
count before dropping the spinlock.

Subject: mlx4_core: Fix possible chunk sg list overflow in mlx4_alloc_icm()

If the number of sg entries in the ICM chunk reaches MLX4_ICM_CHUNK_LEN,
we must set chunk to NULL even for coherent mappings so that the next
time through the loop will allocate another chunk.  Otherwise we'll
overflow the sg list the next time through the loop.  This will lead to
memory corruption if this case is hit.

mthca does not have this bug.

Subject: ixgbe:add support for a new 82599 10G Base-T device

This adds support for a new copper device for 82599, device id 0x151c.
This 82599 10GBase-T device uses the PHY's internal temperature sensor
to guard against over-temp conditions. In this scenario the PHY will be
put in a low power mode and link will no longer be able to transmit or
receive any data. When this occurs, the over-temp interrupt is latched
and driver logs this error message. A HW reset or power cycle is
required to clear this status.

Subject: can: SJA1000 add missing spin_lock_init()

As remarked by Sam Ravnborg the spin_lock variable, that has been introduced
in commit 57c8a456640fa3ca777652f11f2db4179a3e66b6 ("can: Fix SJA1000 command
register writes on SMP systems") has not been initialized properly.

This patch adds the initialization to allow spinlock debugging.

Subject: IB/core: Allow device-specific per-port sysfs files

Add a new parameter to ib_register_device() so that low-level device
drivers can pass in a pointer to a callback function that will be
called for each port that is registered in sysfs.  This allows
low-level device drivers to create files in

    /sys/class/infiniband/<hca>/ports/<N>/

without having to poke through the internals of the RDMA sysfs handling.

There is no need for an unregister function since the kobject
reference will go to zero when ib_unregister_device() is called.

Subject: block,ide: simplify bdops->set_capacity() to
 ->unlock_native_capacity()

bdops->set_capacity() is unnecessarily generic.  All that's required
is a simple one way notification to lower level driver telling it to
try to unlock native capacity.  There's no reason to pass in target
capacity or return the new capacity.  The former is always the
inherent native capacity and the latter can be handled via the usual
device resize / revalidation path.  In fact, the current API is always
used that way.

Replace ->set_capacity() with ->unlock_native_capacity() which take
only @disk and doesn't return anything.  IDE which is the only current
user of the API is converted accordingly.

Subject: iwlwifi: fix internal scan race

It is possible for internal scan to race against itself if the device is
not returning the scan results from first requests. What happens in this
case is the cleanup done during the abort of the first internal scan also
cleans up part of the new scan, causing it to access memory it shouldn't.

Here are details:
* First internal scan is triggered and scan command sent to device.
* After seven seconds there is no scan results so the watchdog timer
  triggers a scan abort.
* The scan abort succeeds and a SCAN_COMPLETE_NOTIFICATION is received for
 failed scan.
* During processing of SCAN_COMPLETE_NOTIFICATION we clear STATUS_SCANNING
  and queue the "scan_completed" work.
** At this time, since the problem that caused the internal scan in first
   place is still present, a new internal scan is triggered.
The behavior at this point is a bit different between 2.6.34 and 2.6.35
since 2.6.35 has a lot of this synchronized. The rest of the race
description will thus be generalized.
** As part of preparing for the scan "is_internal_short_scan" is set to
true.
* At this point the completion work for fist scan is run. As part of this
  there is some locking missing around the "is_internal_short_scan"
  variable and it is set to "false".
** Now the second scan runs and it considers itself a real (not internal0
   scan and thus causes problems with wrong memory being accessed.

The fix is twofold.
* Since "is_internal_short_scan" should be protected by mutex, fix this in
  scan completion work so that changes to it can be serialized.
* Do not queue a new internal scan if one is in progress.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=15824

Subject: wl1271: Fix RX data path frame lengths

The current frame length used by the driver for RX frames is the SPI bus
transfer length. This length has padding bytes, which do not belong to the
WLAN frame.

As there is no other length information in the WLAN frame except the skb
length this problem caused for instance extra ESSID's to be listed at the
end of scan results (IE id 0) with zero length.

Fix the frame length by removing padding.

Subject: ath9k: remove AR9003 from PCI IDs for now

We tried to squeeze as much AR9003 support into this kernel
release cycle but there are a few features which are still
being tested and developed. Some of these features are critical
to the stable operation of AR9003 so for now disable AR9003 support
all together. This will get re-enabled once all necessary features
are in place but very likely will not happen for 2.6.35.

Subject: RTC: rtc-cmos: Fix binary mode support

As a follow-up to the thread about RTC support for some Loongson 2E/2F
boards, this patch tries to address the "REVISIT"/"FIXME" comments about
rtc binary mode handling and allow rtc to work with rtc in binary mode.
I've also raised the message about 24-h mode not supported to warning
otherwise, one may end up with no rtc without any message in the kernel
log.

Subject: PCI: Allow manual resource allocation for PCI hotplug bridges

At the moment only PCI-E briges can be flagged as hotplug, thus
allowing manual resource preallocation via pci=hpmemsize=nnM and
pci=hpiosize=nnM kernel parameters. Some PCI hotplug bridges, e.g.
PLX 6254 can also benefit from this functionalily, as kernel fails
to properly allocate their resources when hotplug device is added
and PCI bus is rescanned.

This patch adds header quirk for PLX 6254 that marks this bridge
as hotplug. Other PCI bridges with similar problems can use it
as well.

Subject: PCI: hotplug: pciehp: Removed check for hotplug of display devices

Removed check to prevent hotplug of display devices within pciehp.
Originally this was thought to have been required within the PCI
Hotplug specification for some legacy devices.  However there is
no such requirement in the most recent revision. The check prevents
hotplug of not only display devices but also computational GPUs
which require serviceability.

Subject: sanitize vfs_fsync calling conventions

Now that the last user passing a NULL file pointer is gone we can remove
the redundant dentry argument and associated hacks inside vfs_fsynmc_range.

The next step will be removig the dentry argument from ->fsync, but given
the luck with the last round of method prototype changes I'd rather
defer this until after the main merge window.

Subject: ACPI: delete unused c-state promotion/demotion data strucutures

These were used before cpuidle by the native ACPI idle driver,
which tracked promotion and demotion between states.

The code was referenced by CONFIG_ACPI_PROCFS
for /proc/acpi/processor/*/power,
but as we no longer do promotion/demotion, that
reference has been a NOP since the transition.

Subject: arch/powerpc: Move dma_mask from of_device into pdev_archdata

By moving dma_mask into pdev_archdata, and adding archdata to
struct of_device, it makes it possible to substitute of_device
with struct platform_device, which is a stepping stone to
removing the of_platform bus entirely.

OF-style matching can be available to any device, on any type of bus.
This patch allows any driver to provide an OF match table when CONFIG_OF

Subject: of: Remove duplicate fields from of_platform_driver

.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

Date: Tue, 13 Apr 2010 16:13:22 -0700
Subject: of: change of_match_device to work with struct device

The of_node pointer is now stored directly in struct device, so
of_match_device() should work with any device, not just struct of_device.

This patch changes the interface to of_match_device() to accept a
struct device instead of struct of_device.

Subject: mmc: add DMA support to tmio_mmc driver, when used on SuperH

SDHI controllers on SuperH, served by the tmio_mmc driver, can use slave DMA
for data transfer. This patch adds support for the dmaengine API to the
tmio_mmc driver.

Subject: tmio: add a platform flag to disable card write-protection detection

Write-protection status is not always available, e.g., micro-SD cards do not
have a write-protection switch at all. This patch adds a flag to let platforms
force tmio_mmc to consider the card writable.

Subject: spi/spi_mpc8xxx: fix potential memory corruption.

tx_dma/rx_dma are already set to a dummy buffer when no
tx/rx buffer and t->tx_dma/t->rx_dma does not contain a dma
address, but NULL.
This may lead to corruption of kernel memory. Fix this by
leaving tx_dma/rx_dma alone.

Do not INIT_TX_RX while controller is enabled, this is bad according
to the MPC8321 manual.

From b3040e40675ec2c43542331cd30d4ee3dae797e8 Mon Sep 17 00:00:00 2001
From: Jassi Brar <jassi.brar@samsung.com>

Subject: DMA: PL330: Add dma api driver

Add DMA Engine API driver for the PL330 DMAC.
This driver is supposed to be reusable by various
platforms that have one or more PL330 DMACs.
Atm, DMA_SLAVE and DMA_MEMCPY capabilities have been
implemented.

Subject: IB/ipath: Remove support for QLogic PCIe QLE devices

The ib_qib driver is taking over support for QLogic PCIe QLE devices,
so remove support for them from ib_ipath.  The ib_ipath driver now
supports only the obsolete QLogic Hyper-Transport IB host channel
adapter (model QHT7140).

Subject: ethoc: fix null dereference in ethoc_probe

Dan reported the patch 0baa080c75c: "ethoc: use system memory
as buffer" introduced a potential null dereference.

  1060  free:
  1061          if (priv->dma_alloc)
                    ^^^^^^^^^^^^^^^
	priv can be null here.

He also suggested that the error handling is not complete.

This patch fixes the null priv issue and improves resources
releasing in ethoc_probe() and ethoc_remove().

Subject: isdn/gigaset: remove dummy CAPI method implementations

Dummy implementations for the optional CAPI controller operations
load_firmware and reset_ctr can cause userspace callers to hang
indefinitely. It's better not to implement them at all.

Introduced by commit 867040163f10f2b52b45bc573f330d6eb28f5914 ("sysfs:
add struct file* to bin_attr callbacks") from the driver-core tree
interacting with commit 14bf62cde79423a02a590e02664ed29a36facec1 ("HID:

Subject: Revert "ath9k: Group Key fix for VAPs"

This reverts commit 03ceedea972a82d343fa5c2528b3952fa9e615d5, since it
breaks resume from suspend-to-ram on Rafael's Acer Ferrari One.
NetworkManager thinks everything is ok, but it can't connect to the AP
to get an IP address after the resume.

In fact, it even breaks resume for non-ath9k chipsets: reverting it also
fixes Rafael's Toshiba Protege R500 with the iwlagn driver.  As Johannes
says:

  "Indeed, this patch needs to be reverted. That mac80211 change is wrong
   and completely unnecessary."

Subject: [SCSI] be2iscsi: correct return value in mgmt_invalidate_icds()

This function should return 0 on error.  Returning -1 would cause a
crash.

Also there is an extra space before the newline character and a missing
space between the "for" and the "mgmt_invalidate_icds".  I put the string
on one line.  The current version of checkpatch.pl complains that the
line is too long, but it makes grepping easier.

The IOA status area now includes the new resource path field for 64 bit
adapters.  This patch changes the driver to fix the ioasa structure and to use
the correct structure definition based on the type of adatper.

Subject: [SCSI] ipr: fix a register read to use the correct address for 64 bit
 adapters

Fix ipr_reset_enable_ioa() to read the correct IOA to host interrupt register
address for 64 bit adapters.  We need to read the lower 32 bits, not the upper
32 bits.

Also change the write of the 64 bit mask value to a single writeq instead
of two writel calls.

Finally, use the correct u8 type for the type field in the ipr_resource_entry
structure.

Subject: [SCSI] ipr: set the data list length in the request control block

In bring up testing for the new 64 bit adapters, the first read command failed
after loading the driver.  The cause was that the command requires more than
one scatter gather element and the corresponding code to set the data list
length in the request control block was missing.  This patch adds the correct
assignment.

Subject: [SCSI] ipr: improve interrupt service routine performance

During performance testing on P7 machines it was observed that the interrupt
service routine was doing unnecessary MMIO operations.

This patch rearranges the logic of the routine and moves some of the code out
of the main routine.  The result is that there are now fewer MMIO operations in
the performance path of the code.

Subject: HID: Add the GYR4101US USB ID to hid-gyration

This change adds in the USB product ID for the Gyration
GYR4101US USB media center remote control.  This remote
is similar enough to the other two devices that this driver
can be used without any other changes to get full support
for the remote.

Subject: ath5k: consistently use rx_bufsize for RX DMA

We should use the same buffer size we set up for DMA also in the hardware
descriptor. Previously we used common->rx_bufsize for setting up the DMA
mapping, but used skb_tailroom(skb) for the size we tell to the hardware in the
descriptor itself. The problem is that skb_tailroom(skb) can give us a larger
value than the size we set up for DMA before. This allows the hardware to write
into memory locations not set up for DMA. In practice this should rarely happen
because all packets should be smaller than the maximum 802.11 packet size.

On the tested platform rx_bufsize is 2528, and we allocated an skb of 2559
bytes length (including padding for cache alignment) but sbk_tailroom() was
2592. Just consistently use rx_bufsize for all RX DMA memory sizes.

Also use the return value of the descriptor setup function.

Don't use to_pci_dev in rt2x00pci_uninitialize to get the allocated irq
as it won't work for platform devices (SoC). Instead, use the irq field
that's already used everywhere else.

(Based on a patch created by Ondrej Zary)

In some circumstances the Ralink devices do not properly go to sleep
or wake up, with timeouts occurring.
Fix this by retrying telling the device that it has to wake up or
sleep.

Subject: rt2x00: Fix rt2800usb TX descriptor writing.

The recent changes to skb handling introduced a bug in the rt2800usb
TX descriptor writing whereby the length of the USB packet wasn't
calculated correctly.
Found via code inspection, as the devices themselves didn't seem to mind.

This is obviously a small picky thing.  The original error handling code
doesn't free the most recent allocations which haven't been added to the
hif_dev->tx.tx_buf list yet.

Subject: iwlwifi: testing the wrong variable in iwl_add_bssid_station()

The intent here is to test that "sta_id_r" is a valid pointer.  We do
this same test later on in the function.

Btw iwl_add_bssid_station() is called from two places and "sta_id_r" is
a valid pointer from both callers.

Subject: ath9k: Fix rx of mcast/bcast frames in PS mode with auto sleep

The functionality to keep the device awake until it is done with
the rx of any mcast/bcast frames which are pending on AP should
also be added to the hardwares which support auto sleep feature.
This patch fixes frequent failures in ARP resolution when it is
initiated by the other end. Currently auto sleep is enabled only
for ar9003 in ath9k.

Subject: RDMA/cxgb4: Optimize CQ overflow detection

1) save the timestamp flit in the cq when we consume a CQE.

2) always compare the saved flit with the previous entry flit when
   reading the next CQE entry.  If the flits don't compare, then we
   have overflowed.

Subject: RDMA/nes: Async event for closed QP causes crash

Under abnormal termination, modify_qp() closes the QP, and async event
(AE) handling also attempts to close the same QP, causing a crash.
Fix this by checking the state of the QP before processing the AE.

Subject: spi/spi_mpc8xxx: Fix QE mode Litte Endian

QE mode uses Little Endian so words > 8 bits are byte swapped.
Workaround this by always enforcing wordsize 8 for words
> 8 bits. Unfortunately this will not work for LSB transfers
where wordsize is > 8 bits so disable these for now.

Also move the different quirks into its own function to keep
mpc8xxx_spi_setup_transfer() sane.

From 781c7b129b1beb876905f7212927aa0ee1b022e5 Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@stericsson.com>
Date: Fri, 7 May 2010 08:40:53 +0000
Subject: spi/pl022: add support for the PL023 derivate

This adds support for a further ST variant of the PL022 called
PL023. Some differences in the control registers due to being
stripped down to SPI mode only, and a new clock feedback sample
delay config setting is available.

Subject: spi/omap2_mcspi: change default DMA_MIN_BYTES value to 160

The value 160 has been obtained as optimal in testing it for
wl1271 which use spi for communication.
In some sense this change might also influence on other spi devices
connected to omap2_mcspi controller.

Subject: spi/omap2_mcspi: add turbo mode support

Turbo mode allows to read data to shift register when rx-buffer
is full thus improving the perfomance. This feature is available
for RX-only mode.

In PIO turbo mode when the penultimate word is available
in RX-buffer the controller should be disabled before reading data
to prevent the next transaction triggering. The controller itself
handles the last word to be correctly loaded to shift-register and
then transferred to RX-buffer.

The turbo mode is enabled by setting turbo_mode parameter to 1.
This parameter is a part of omap2_mcspi_device_config structure
which is passed through the spi_device controller_data pointer.

+Cirrus EP93xx SPI controller driver HOWTO
+=========================================
+
+ep93xx_spi driver brings SPI master support for EP93xx SPI controller.  Chip
+selects are implemented with GPIO lines.
+
+NOTE: If possible, don't use SFRMOUT (SFRM1) signal as a chip select. It will
+not work correctly (it cannot be controlled by software). Use GPIO lines
+instead.
+
+Sample configuration
+====================
+
+Typically driver configuration is done in platform board files (the files under
+arch/arm/mach-ep93xx/*.c). In this example we configure MMC over SPI through
+this driver on TS-7260 board. You can adapt the code to suit your needs.
+
+This example uses EGPIO9 as SD/MMC card chip select (this is wired in DIO1
+header on the board).
+
+You need to select CONFIG_MMC_SPI to use mmc_spi driver.

+Thanks to
+=========
+Martin Guy, H. Hartley Sweeten and others who helped me during development of
+the driver. Simplemachines.it donated me a Sim.One board which I used testing
+the driver on EP9307.

From 2da8cb6af5fe0d9e16b8a49399c8b7c6cfa94d5a Mon Sep 17 00:00:00 2001

Subject: powerpc/mpc5121: move PSC FIFO memory init to platform code

Since PSC could also be used in other modes than UART mode
we move PSC FIFO memory initialization from serial driver to
common platform code. The initialized FIFO memory slices may
not overlap, so the most easy way would be to configure them
all at once at init time for all PSC devices. This is now done
by this patch.

Subject: spi: move bitbang txrx utility functions to private header

A number of files in drivers/spi fail checkincludes.pl due to the double
include of <linux/spi/spi_bitbang.h>.

The first include is needed to get the struct spi_bitbang definition and
the spi_bitbang_* function prototypes.

The second include happens after defining EXPAND_BITBANG_TXRX to get the
inlined bitbang_txrx_* utility functions.

The <linux/spi/spi_bitbang.h> header is also included by a number of other
spi drivers, as well as some arch/ code, in order to use struct spi_bitbang
and the associated functions.

To fix the double include, and remove any potential confusion about it, move
the inlined bitbang_txrx_* functions to a new private header in drivers/spi
and also remove the need to define EXPAND_BITBANG_TXRX.

Commit 58f9b0b02414062eaff46716bc04b47d7e79add5, "of: eliminate
of_device->node and dev_archdata->{of,prom}_node" changed the location
of the device_node pointer.  Most drivers were converted to the new
location, but the xilinx_spi_of driver was missed and now fails to
compile.

This patch fixes up the xilinx_spi_of driver to use the new location.

Subject: HID: roccat: propagate special events of roccat hardware to userspace

Module roccat is a char device used to report special events of roccat hardware
to userland. These events include requests for on-screen-display of profile or
dpi settings or requests for execution of macro sequences that are not stored
in device. The information in these events depends on hid device implementation
and contains data that is not available in a single hid event or else hidraw
could have been used.

It is inspired by hidraw, but uses only one circular buffer for all readers.
The device is as generic as possible so that the functionality is usable by all
(kone and upcomming) roccat device drivers.

Subject: watchdog: fix several MODULE_PARM_DESC strings

Fix MODULE_PARM_DESC() strings in several watchdog drivers.
Some are simple as add a parenthesis.
Others are problems from __stringify() being used on a
variable name instead of a macro name, so the variable name
is produced in the string instead of its build-time value.
In these cases, create a macro for the value so that the
module param description string is useful.

Only pc87413_wdt has been built (due to toolchains).

Subject: watchdog: update/improve/consolidate watchdog driver

Move the limited watchdog driver help from kernel-parameters.txt
to Documentation/watchdog/watchdog-parameters.txt and add info to it
for all watchdog drivers except the ones that have driver-specific
files already.

Correct minor comments and MODULE_PARM_DESC() text in 2 places.

Subject: iTCO_wdt: fix TCO V1 timeout values and limits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For TCO V1 devices the programmed timeout was twice too long
because the fact that the TCO V1 timer needs to count down
twice before triggering the watchdog, wasn't accounted for.
Also the timeout values in the module description and error
message were clarified. And the _STS registers are 16 bit
instead of 8 bit.

Subject: regulator: Allow regulator-regulator supplies to be specified by name

When one regulator supplies another allow the relationship to be specified
using names rather than struct regulators, in a similar manner to that
allowed for consumer supplies. This allows static configuration at compile
time, reducing the need for dynamic init code.

Also change the references to LINE supply to be system supply since line
is sometimes used for actual supplies and therefore potentially confusing.

Subject: regulator: prevent registration of matching regulator consumer
 supplies

Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Pointer comparison is not sufficient for non-NULL device name matching,
so use strcmp(). Otherwise the semantics remain the same.

Subject: regulator: use voltage number array in 88pm860x

A lot of condition comparision statements are used in original driver. These
statements are used to check the boundary of voltage numbers since voltage
number isn't linear.

Now use array of voltage numbers instead. Clean code with simpler way.

Subject: mc13783-regulator: fix vaild voltage range checking for
 mc13783_fixed_regulator_set_voltage

In the case of "min_uV == max_uV == mc13783_regulators[id].voltages[0]",
mc13783_fixed_regulator_set_voltage should return 0 instead of -EINVAL.

This patch also adds a missing ">" character for MODULE_AUTHOR, a trivial fix.

Subject: twl6030: regulator: Remove vsel tables and use formula for
 calculation

All twl6030 regulators can be programmed from 1.0v to 3.3v
with 100mV steps.
The below formula can be used to calculate the vsel values
to be programmed in the VREG_VOLTAGE registers.

Voltage(in mV) = 1000mv + 100mv * (vsel - 1)

Ex: if vsel = 0x9, mV = 1000 + 100 * (9 -1) = 1800mV.

This patch removes all existing VSEL tables for twl6030 adjustable
regulators and just uses the formula directly for vsel calculations
after verifing they fall in the allowed range.

True. In such a case, even a valid request would be lost! So now
in the updated patch:
 - check if get_mode is present to avoid oops;
 - if get_mode is not present, proceed anyways for the request.

Here is the updated patch:

Subject: power_supply: Fix regression for 'type' property

Commit 5f487cd34f4337f9bc27ca19da72a39d1b0a0ab4 (power_supply: Use
attribute groups) causes a regression the power supply core does not
export the 'type' attribute anymore.

POWER_SUPPLY_PROP_TYPE is handled by the power supply core without the
low-level driver, so power_supply_attr_is_visible() must always return
the entry as readable.

Subject: mm: compaction: add /sys trigger for per-node memory compaction

Add a per-node sysfs file called compact.  When the file is written to,
each zone in that node is compacted.  The intention that this would be
used by something like a job scheduler in a batch system before a job
starts so that the job can allocate the maximum number of hugepages
without significant start-up cost.

Commit 8b505ca8e2600eb9e7dd2d6b2682a81717671374 ("serial: 68328serial.c:
remove BAUD_TABLE_SIZE macro") misses one use of BAUD_TABLE_SIZE.  So the

drivers/serial/68328serial.c:1439: error: (Each undeclared identifier is reported only once

Subject: cpuidle: add a repeating pattern detector to the menu governor

Currently, the menu governor uses the (corrected) next timer as key item
for predicting the idle duration.

It turns out that there are specific cases where this breaks down: There
are cases where we have a very repetitive pattern of idle durations, where
the idle period is pretty much the same, for reasons completely unrelated
to the next timer event.  Examples of such repeating patterns are network
loads with irq mitigation, the mouse moving but in theory also the wifi
beacons.

This patch adds a relatively simple detector for such repeating patterns,
where the standard deviation of the last 8 idle periods is compared to a
threshold.

With this extra predictor in place, measurements show that the DECAY
factor can now be increased (the decaying average will now decay slower)
to get an even more stable result.

occasionally as far as google search can tell.

First, the following line overflows unsigned long:

# define TIMER_FREQ (HZ*loops_per_jiffy)

Second, and more importantly, loops_per_jiffy has little to do with the
con= version from the the time scale of get_cycles() (aka rdtsc) to the
time scale of jiffies.

The attached patch resolves both of the problems.

From 4be929be34f9bdeffa40d815d32d7d60d2c7f03b Mon Sep 17 00:00:00 2001
From: Alexey Dobriyan <adobriyan@gmail.com>
Date: Mon, 24 May 2010 14:33:03 -0700
Subject: kernel-wide: replace USHORT_MAX, SHORT_MAX and SHORT_MIN with
 USHRT_MAX, SHRT_MAX and SHRT_MIN

- C99 knows about USHRT_MAX/SHRT_MAX/SHRT_MIN, not
  USHORT_MAX/SHORT_MAX/SHORT_MIN.

- Make SHRT_MIN of type s16, not int, for consistency.

Subject: drivers: misc: pass miscdevice pointer via file private data

For misc devices, inode->i_cdev doesn't point to the device drivers own
data.  Link between file operations and device driver internal data is
lost.  Pass pointer to misc device struct via file private data for driver
open function use.

Split the bus logic out into separate files so that we can handle I2C and
SPI busses independently.  The new SPI bus logic brings in support for a
lot more parts:

Subject: lis3: introduce platform data for second ff / wu unit

8 bit device has two wakeup / free fall units.  It was not possible to
configure the second unit.  This patch introduces configuration entry to
the platform data and also corresponding changes to the 8 bit setup
function.

High pass filters were enabled by default.  Patch introduces configuration
option for high pass filter cut off frequency and also possibility to
disable or enable the filter via platform data.  Since the control is a
new one and default state was filter enabled, new option is used to
disable the filter.  This way old platform data is still compatible with
the change.

Original lis3 driver didn't provide interrupt handler(s) for click or
threshold event handling.  This patch adds threaded handlers for one or
two interrupt lines for 8 bit device.  Actual content for interrupt
handling is provided in the separate patch.

Subject: lis3: interrupt handlers for 8bit wakeup and click events

Content for the 8bit device threaded interrupt handlers.  Depending on the
interrupt line and chip configuration, either click or wakeup / freefall
handler is called.  In case of click, BTN_ event is sent via input device.
 In case of wakeup or freefall, input device ABS_ events are updated
immediatelly.

It is still possible to configure interrupt line 1 for fast freefall
detection and use the second line either for click or threshold based
interrupts.  Or both lines can be used for click / threshold interrupts.

Polled input device can be set to stopped state and still get coordinate
updates via input device using interrupt based method.  Polled mode and
interrupt mode can also be used parallel.

BTN_ events are remapped based on existing axis remapping information.

On imx SoCs rtc clock parent is CKIL, but clock rate shall be determined
using rtc clock itself, that eliminates CKIL clock usage in the driver.

Instead of individually creating and removing the sysfs device attribute
files, wrap them in an attribute_group and use
sysfs_{create/remove}_group.

Subject: rtc-ds1302: add some abstraction for new platform support

The current ds1302 driver (or at least the one that lives in /drivers/rtc)
seems to be designed for memory mapped devices only.  This make it quite
hard to add support for GPIO-based implementations (as this is the case
for the upcoming Arcom Vulcan).

This patch moves the direct register access to inline functions with
explicit names.  Still not as good as a proper platform driver, but at
least neater.

Subject: rtc-cmos: do dev_set_drvdata() earlier in the initialization

The bug is an oops when dev_get_drvdata() returned null in
cmos_update_irq_enable().  The call tree looks like this:
  rtc_dev_ioctl()
    => rtc_update_irq_enable()
      => cmos_update_irq_enable()

It's caused by a race condition in the module initialization.  It is
rtc_device_register() which makes the ioctl operations live so I moved
the call to dev_set_drvdata() before the call to rtc_device_register().

Subject: rtc: use genirq directly in rtc-wm831x

Now that the WM831x core uses genirq for the IRQ controller there is no
need to use the WM831x-specific wrappers to request interrupts so convert
to use genirq directly.

Also use more meaningful strings to make /proc/interrupts more readily
legible.

Subject: fbdev: section cleanup in arcfb
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix the sections in the arcfb driver, by moving:

*	the variables arcfb_fix and arcfb_var from .init.data to .devinit.data

*	arcfb_remove() from .text to .devexit.text

This fixes the following warnings issued by modpost:

WARNING: drivers/video/built-in.o(.devinit.text+0x543): Section mismatch in reference from the function arcfb_probe() to the variable .init.data:arcfb_var
The function __devinit arcfb_probe() references
a variable __initdata arcfb_var.
If arcfb_var is only used by arcfb_probe then
annotate arcfb_var with a matching annotation.

WARNING: drivers/video/built-in.o(.devinit.text+0x558): Section mismatch in reference from the function arcfb_probe() to the variable .init.data:arcfb_fix
The function __devinit arcfb_probe() references
a variable __initdata arcfb_fix.
If arcfb_fix is only used by arcfb_probe then
annotate arcfb_fix with a matching annotation.

Subject: fbdev: section cleanup in vfb
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix up the section in the vfb driver, by moving the variables vfb_default
and vfb_fix from .init.data to .devinit.data

This fixes the following warnings issued by modpost:

WARNING: drivers/video/vfb.o(.devinit.text+0xf8): Section mismatch in reference from the function vfb_probe() to the variable .init.data:vfb_default
The function __devinit vfb_probe() references
a variable __initdata vfb_default.
If vfb_default is only used by vfb_probe then
annotate vfb_default with a matching annotation.

WARNING: drivers/video/vfb.o(.devinit.text+0x114): Section mismatch in reference from the function vfb_probe() to the variable .init.data:vfb_fix
The function __devinit vfb_probe() references
a variable __initdata vfb_fix.
If vfb_fix is only used by vfb_probe then
annotate vfb_fix with a matching annotation.

Subject: fbdev: da8xx/omap-l1xx: implement double buffering

This work includes the following:

- Implement handler for FBIO_WAITFORVSYNC ioctl.

- Allocate the data and palette buffers separately.  A consequence of
  this is that the palette and data loading is now done in different
  phases.  And that the LCD must be disabled temporarily after the palette
  is loaded but this will only happen once after init and each time the
  palette is changed.  I think this is OK.

- Allocate two (ping and pong) framebuffers from memory.

- Add pan_display handler which toggles the LCDC DMA registers between
  the ping and pong buffers.

Subject: fbdev: move FBIO_WAITFORVSYNC to linux/fb.h

FBIO_WAITFORVSYNC is currently implemented by matroxfb, atyfb, intelfb and
more.  All of them keep redefining the same FBIO_WAITFORVSYNC macro over
and over again, so move it to linux/fb.h and clean up those duplicate
defines.

Subject: sgivwfb: fix sections

Since the drivers probe call was changed from .init.text to .devinit.text
in commit c2e13037e6794bd0d9de3f9ecabf5615f15c160b ("platform-drivers:
move probe to .devinit.text in drivers/video") the fb_fix_screeninfo and
fb_var_screeninfo structures must be changed from .init.data to
.devinit.data, too.

Also the drivers remove routine should be moved from .text to .devexit.text

It removes these 7 section mismatch warnings from modpost:

Subject: fb_defio: fix for non-dirty ptes

Fix a problem observed while using fb_defio with a short delay on a
PowerPC platform.

It is possible that page_mkclean() is invoked in the deferred io work
function _before_ a PTE has been marked dirty.  In this case, the page is
removed from the defio pagelist but page_mkclean() does not write-protect
the page again.  The end result is that defio ignores all subsequent
writes to the page and the corresponding portions of the framebuffer never
get updated.

The fix consists in keeping track of the pages with non-dirty PTEs,
re-checking them again on the next deferred io work iteration.  Note that
those pages are not passed to the defio callback as they are not written
by userspace yet.

Subject: ath9k: remove VEOL support for ad-hoc

With VEOL, Beacon transmission in ad-hoc does not currently work.
I believe for larger ad-hoc networks, VEOL is too unreliable, as
it can get beacon transmissions stuck during synchronization.
Use SWBA based beacon trasmission similar to AP mode instead.

Subject: SFI: add support for v0.81 spec

There are 2 major changes from v0.81 to v0.7:
1. Consolidating the SPIB/I2CB tables into a new DEVS table,
   which is more expandable and can support other bus types
   than spi/i2c.
2. Creating a new GPIO table, which list all the GPIO pins
   used in the platform.

However, to avoid breaking current platforms who use SFI v0.7
version firmware, the definitions for SPIB/I2CB will still
be kept for a while

Subject: [SCSI] fix race in scsi_target_reap

This patch (as1357) fixes a race in SCSI target allocation and
release.  Putting a target in the STARGET_DEL state isn't protected by
the host lock, so an old target structure could be reused by a new
device even though it's about to be deleted.  The cure is to change
the state while still holding the host lock.

Subject: RDMA/nes: Fix incorrect unlock in nes_process_mac_intr()

Commit ce6e74f2 ("RDMA/nes: Make nesadapter->phy_lock usage
consistent") introduced a problem where phy_lock was only unlocked
within an if statement and so nes_process_mac_intr() could return with
phy_lock still held.  Fix this.

This was discovered because of the sparse warning:

    drivers/infiniband/hw/nes/nes_hw.c:2643:9: warning: context imbalance in 'nes_process_mac_intr' - different lock contexts for basic block

Subject: driver core: add devname module aliases to allow module on-demand
 auto-loading

This adds:
  alias: devname:<name>
to some common kernel modules, which will allow the on-demand loading
of the kernel module when the device node is accessed.

Ideally all these modules would be compiled-in, but distros seems too
much in love with their modularization that we need to cover the common
cases with this new facility. It will allow us to remove a bunch of pretty
useless init scripts and modprobes from init scripts.

The static device node aliases will be carried in the module itself. The
program depmod will extract this information to a file in the module directory:
  $ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname
  # Device nodes to trigger on-demand module loading.
  microcode cpu/microcode c10:184
  fuse fuse c10:229
  ppp_generic ppp c108:0
  tun net/tun c10:200
  dm_mod mapper/control c10:235

Udev will pick up the depmod created file on startup and create all the
static device nodes which the kernel modules specify, so that these modules
get automatically loaded when the device node is accessed:
  $ /sbin/udevd --debug
  ...
  static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184
  static_dev_create_from_modules: mknod '/dev/fuse' c10:229
  static_dev_create_from_modules: mknod '/dev/ppp' c108:0
  static_dev_create_from_modules: mknod '/dev/net/tun' c10:200
  static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235
  udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666
  udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666

A few device nodes are switched to statically allocated numbers, to allow
the static nodes to work. This might also useful for systems which still run
a plain static /dev, which is completely unsafe to use with any dynamic minor
numbers.

Note:
The devname aliases must be limited to the *common* and *single*instance*
device nodes, like the misc devices, and never be used for conceptually limited
systems like the loop devices, which should rather get fixed properly and get a
control node for losetup to talk to, instead of creating a random number of
device nodes in advance, regardless if they are ever used.

This facility is to hide the mess distros are creating with too modualized
kernels, and just to hide that these modules are not compiled-in, and not to
paper-over broken concepts. Thanks! :)

Subject: be2net: Bug fix to avoid disabling bottom half during firmware
 upgrade.

Certain firmware commands/operations to upgrade firmware could take several
seconds to complete. The code presently disables bottom half during these
operations which could lead to unpredictable behaviour in certain cases. This
patch now does all firmware upgrade operations asynchronously using a
completion variable.

Subject: drivers/net/usb/asix.c: Fix pointer cast.

Stephen Rothwell reports the following new warning:

drivers/net/usb/asix.c: In function 'asix_rx_fixup':
drivers/net/usb/asix.c:325: warning: cast from pointer to integer of different size
drivers/net/usb/asix.c:354: warning: cast from pointer to integer of different size

The code just cares about the low alignment bits, so use
an "unsigned long" cast instead of one to "u32".

Subject: sata_mv: drop unncessary EH callback resetting

Now that BMDMA EH ops are separated out from SFF ops, mv5_ops doesn't
have to explicitly reset ->error_handler() and ->post_internal_cmd().
Drop them.

Subject: libata-sff: ata_sff_irq_clear() is BMDMA specific

ata_sff_irq_clear() is BMDMA specific.  Rename it to
ata_bmdma_irq_clear(), move it to ata_bmdma_port_ops and make
->sff_irq_clear() optional.

Note: ata_bmdma_irq_clear() is actually only needed by ata_piix and
      possibly by sata_sil.  This should be moved to respective low
      level drivers later.

Subject: libata-sff: separate out BMDMA irq handler

Separate out BMDMA irq handler from SFF irq handler.  The misnamed
host_intr() functions are renamed to ata_sff_port_intr() and
ata_bmdma_port_intr().  Common parts are factored into
__ata_sff_port_intr() and __ata_sff_interrupt() and used by sff and
bmdma interrupt routines.

All BMDMA drivers now use ata_bmdma_interrupt() or
ata_bmdma_port_intr() while all non-BMDMA SFF ones use
ata_sff_interrupt() or ata_sff_port_intr().

For now, ata_pci_sff_init_one() uses ata_bmdma_interrupt() as it's
used by both SFF and BMDMA drivers.

From 1c5afdf7a629d2e77de8dd043b97a33dcd7e6dfa Mon Sep 17 00:00:00 2001
From: Tejun Heo <tj@kernel.org>
Date: Wed, 19 May 2010 22:10:22 +0200
Subject: libata-sff: separate out BMDMA init

Separate out ata_pci_bmdma_prepare_host() and ata_pci_bmdma_init_one()
from their SFF counterparts.  SFF ones no longer try to initialize
BMDMA or set PCI master.

Subject: libata-sff: kill dummy BMDMA ops from sata_qstor and pata_octeon_cf

Now that SFF and BMDMA are completely separate, sata_qstor and
pata_octeon_cf which inherit from ata_sff_port_ops don't need to worry
about BMDMA ops being called.  Kill the dummy BMDMA ops.

Subject: libata-sff: make BMDMA optional

Make BMDMA optional depending on new config variable CONFIG_ATA_BMDMA.
In Kconfig, drivers are grouped into five groups - non-SFF native, SFF
w/ custom DMA interface, SFF w/ BMDMA, PIO-only SFF, and generic
fallback / legacy ones.  Kconfig and Makefile are reorganized
according to the groups and ordered alphabetically inside each group.

ata_ioports.bmdma_addr and ata_port.bmdma_prd[_dma] are put into
CONFIG_ATA_BMDMA, as are all bmdma related ops, variables and
functions.

This increase the binary size slightly when BMDMA is enabled but on
both native-only and PIO-only configurations the size is slightly
reduced.  Either way, the size difference is insignificant.  This
change is more meaningful to signify the separation between SFF and
BMDMA and as a tool to verify the separation.

From: Tejun Heo <tj@kernel.org>

Subject: libata: disable ATAPI AN by default

There are ATAPI devices which raise AN when hit by commands issued by
open().  This leads to infinite loop of AN -> MEDIA_CHANGE uevent ->
udev open() to check media -> AN.

Both ACS and SerialATA standards don't define in which case ATAPI
devices are supposed to raise or not raise AN.  They both list media
insertion event as a possible use case for ATAPI ANs but there is no
clear description of what constitutes such events.  As such, it seems
a bit too naive to export ANs directly to userland as MEDIA_CHANGE
events without further verification (which should behave similarly to
windows as it apparently is the only thing that some hardware vendors
are testing against).

This patch adds libata.atapi_an module parameter and disables ATAPI AN
by default for now.

drivers/gpu/drm/radeon/atombios_crtc.c:684: warning: 'pll' may be used uninitialized in this function
which has the looks of a falso positive.

Add a default: case so that gcc rests assured that all possible pll_id's are covered.
Keep the present cases that fall through to the default one for self-documentation.

Subject: n2_crypto: Plumb fallback ahash requests properly.

Do this by putting the async fallback request at the end of an n2
specific ahash request context, then properly adjusting the request
private size in our ahash ->cra_init().

We also need to put the writable state bits into the n2 request
private instead of the n2 cra_ctx.

With help from Herbert Xu.

Stanse found pci reference leaks in uli_agp_init and nforce3_agp_init
initialization functions.

The PCI devices are bridges, so it's not critical, but still worth fixing.

Subject: leds: leds-gpio: Change blink_set callback to be able to turn off
 blinking

The leds-gpio blink_set() callback follows the same prototype as the
main leds subsystem blink_set() one.

The problem is that to stop blink, normally, a leds driver does it
in the brightness_set() callback when asked to set a new fixed value.

However, with leds-gpio, the platform has no hook to do so, as this
later callback results in a standard GPIO manipulation.

This changes the leds-gpio specific callback to take a new argument
that indicates whether the LED should be blinking or not and in what
state it should be set if not. We also update the dns323 platform
which seems to be the only user of this so far.

Subject: leds: leds-lp3944: properly handle lp3944_configure fail in
 lp3944_probe

In current implementation, lp3944_probe return 0 even if lp3944_configure fail.
Therefore, led_classdev_unregister will be executed twice
( in error handling of lp3944_configure and lp3944_remove ).
This patch properly handles lp3944_configure fail in lp3944_probe.

Subject: leds: leds-ss4200: fix led_classdev_unregister twice in error
 handling

In current implementation, if device_create_file failed in register_nasgpio_led,
led_classdev_unregister will be executed twice.
( in register_nasgpio_led it calls led_classdev_unregister before return and in nas_gpio_init out_err )

This patch fixes it by only unregistering those that were successfully registered in out_err.
( not including last failed register_nasgpio_led call )

Cleanup the "depends on" logic by wrapping the affected config options in
appropriate if/endif blocks.

Remove all the "default n" since that is the default default.

Fix DMI_SYS_VENDOR for MacBook1,1.

When the MacBook1,1 came out Apple was still named Apple Computer, I am
not sure if this applies to older MacBook2,1 versions aswell.

Subject: backlight: add S6E63M0 AMOLED LCD Panel driver

This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI
interface also almost features for lcd panel driver has been implemented
in here.  and I added new structure common for all the lcd panel drivers
to include/linux/lcd.h file.

LCD Panel driver needs interfaces for controlling device power such as
power on/off and reset.  these interfaces are device specific so it should
be implemented to machine code at this time, we should create new
structure for registering these functions as callbacks and also a header
file for that structure and finally registered callback functions would be
called by lcd panel driver.  such header file(including new structure for
lcd panel) would be added for all the lcd panel drivers.

If anyone provides common structure for registering such callback
functions then we could reduce unnecessary header files for lcd panel.  I
thought that suitable anyone could be include/linux/lcd.h so a new
lcd_platform_data structure was added there.

Subject: backlight: l4f00242t03: fix error handling in l4f00242t03_probe

Error handling fixes:
1. In the case of kzalloc failure, simple return -ENOMEM instead of goto
   err. ( priv is NULL in this case )
2. In the case of gpio_request fail for reset_gpio and data_enable_gpio,
   properly release resources by goto err and err2 respectively.

This reverts commit 663cb47cc2c5acd32850f67d051e47d62ed199c9.

This patch was merged out of the proper order, so instead of fixing a
problem with a prior (unmerged) patch, it creates one.  Ooops!

Subject: drm/i915: Fail to load driver if KMS request without GEM

The i915's implementation of KMS requires GEM in order to manage the
memory and execution domains of the framebuffer and associated
resources. By the point at which we detect broken a BIOS and need to
disable GEM, we have already registered ourselves as a KMS driver with
several subsystems. Rather than introducing a fragile unwind and attempt
to continue with UMS, spit out an error and unload the driver.

Subject: drm/i915: Move ringbuffer-related code to intel_ringbuffer.c.

This is preparation for supporting multiple ringbuffers on Ironlake.
The non-copy-and-paste changes are:
- de-staticing functions
- I915_GEM_GPU_DOMAINS moving to i915_drv.h to be used by both files.
- i915_gem_add_request had only half its implementation
  copy-and-pasted out of the middle of it.

Subject: IB/qib: Don't rely on (undefined) order of function parameter
 evaluation

Some of the qib sysfs code passes a buffer pointer into
simple_read_from_buffer() but relies on a function call in another
parameter of the same call to initialize that pointer.  Since the order
of evaluation of function parameters is undefined, this will break if
gcc chooses the wrong order.

Fix this by splitting the code into two separate function calls.

This was noticed because of warnings like the following on ppc:

    drivers/infiniband/hw/qib/qib_fs.c: In function 'portcntrs_2_read':
    drivers/infiniband/hw/qib/qib_fs.c:203: warning: 'counters' is used uninitialized in this function

From 852835f343146a82a528c3b712b373661d4fa17a Mon Sep 17 00:00:00 2001
From: Zou Nan hai <nanhai.zou@intel.com>

Subject: drm/i915: convert some gem structures to per-ring V2

The active list and request list move into the ringbuffer structure,
so each can track its active objects in the order they are in that
ring.  The flushing list does not, as it doesn't matter which ring
caused data to end up in the render cache.  Objects gain a pointer to
the ring they are active on (if any).

From d1b851fc0d105caa6b6e3e7c92d2987dfb52cbe0 Mon Sep 17 00:00:00 2001
From: Zou Nan hai <nanhai.zou@intel.com>
Date: Fri, 21 May 2010 09:08:57 +0800
Subject: drm/i915: implement BSD ring buffer V2

The BSD (bit stream decoder) ring is used for accessing the BSD engine
which decodes video bitstream for H.264 and VC1 on G45+.  It is
asynchronous with the render ring and has access to separate parts of
the GPU from it, though the render cache is coherent between the two.

From 9517a92f48b08bb02cfb616825850b82b28461cc Mon Sep 17 00:00:00 2001

Subject: drm/i915: add timeout to FBC disable waits

FBC disable on 965 can take long enough to trigger latency checks in the
kernel so be sure to timeout after a reasonable period.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15015.

Subject: drm/i915: Add support for interlaced display.

This doesn't change the clock limits (minimums), i.e. it won't make it
output 720x576 PAL nor 720x480 NTSC, but it will work with modes like
1080i etc. (including GLX and textured Xvideo, not sure about the
overlay).

Tested on i915 + analog VGA, it would be worth checking if newer chips
(and which ones) still support interlaced mode.

Disable the CRT plug interrupt while doing the force cycle, explicitly
clear any CRT interrupt we may have generated, and restore when done.
Should mitigate interrupt storms from hotplug detection.

Subject: drm/i915: add power monitoring support

Add power monitoring support to the i915 driver for use by the IPS
driver.  Export the available power info to the IPS driver through a few
new inter-driver hooks.  When used together, the IPS driver and this
patch can significantly increase graphics performance on Ironlake class
chips.

Subject: drm/i915: Storage class should be before const qualifier

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

  https://bugzilla.kernel.org/show_bug.cgi?id=15733

On G33 and above, the size of the GTT space is determined by the GMCH
control register. Prior to this revision, the size is determined by the
size of the aperture. So we must careful to map and fill the appropriate
range depending on chipset.

Subject: drm/i915: Kill dangerous pending-flip debugging

We can, by virtue of a vblank interrupt firing in the middle of setting
up the unpin work (i.e. after we set the unpin_work field and before we
write to the ringbuffer) enter intel_finish_page_flip() prior to
receiving the pending flip notification. Therefore we can expect to hit
intel_finish_page_flip() under normal circumstances without a pending flip
and even without installing the pending_flip_obj. This is exacerbated by
aperture thrashing whilst binding the framebuffer

Subject: [S390] cio: remove stsch

Since 8821d24cd261aede9b0436cd3252b17a60ccc33a we no longer
use the plain stsch inline function but the one which can
handle exceptions. Remove the unused function.

From a77fcf895046664927dd6eea816602b87a1a6337 Mon Sep 17 00:00:00 2001
From: Ralph Campbell <ralph.campbell@qlogic.com>
Date: Wed, 26 May 2010 16:08:44 -0700
Subject: IB/qib: Use a single txselect module parameter for serdes tuning

As part of the earlier patches submitted and reviewed, it was agreed
to change the way serdes tuning parameters were specified to the
driver.  The updated patch got dropped by the linux-rdma email list so
the earlier version of qib_iba7322.c ended up being used.  This patch
updates qib_iab7322.c to the simpler, single parameter method of
setting the serdes parameters.

The current checksum offload code does not work and this corrects
that functionality. It also updates the interrupt coallescing

Subject: Input: ads7846 - return error on regulator_get() failure

In probe(), if regulator_get() failed, an error code was not being
returned causing the driver to be successfully bound, even though
probe failed.  This in turn caused the suspend, resume and remove
methods to be registered and accessed via the SPI core.  Since these
functions all access private driver data using pointers that had been
freed during the failed probe, this would lead to unpredictable
behavior.

This patch ensures that probe() returns an error code in this failure
case so the driver is not bound.

Found using lockdep and noticing the lock used in the suspend/resum
path pointed to a bogus lock due to the freed memory.

Bigger Nexio touchscreens not only send more data but also the header

it works at least on one 46" touchscreen with 2.00SMS firmware) and
also increase rept_size.

copy_to/from_user() returns the number of bytes that could not be copied.

So we need to check if it is not zero, and in that case, we should return
the error number -EFAULT rather than directly return the return value from
copy_to/from_user().

So we need to check if it is not zero, and in that case, we should return
the error number -EFAULT rather than directly return the return value from
copy_to/from_user().

Subject: davinci: mmc: pass number of SG segments as platform data

On some platforms like DM355, the number of EDMA parameter slots available
for EDMA_SLOT_ANY usage are few.  In such cases, if MMC/SD uses 16 slots
for each instance of MMC controller, then the number of slots available
for other modules will be very few.

By passing the number of EDMA slots to be used in MMC driver from platform
data, EDMA slots available for other purposes can be controlled.

Most of the platforms will not use this platform data variable.  But on
DM355, as the number of EDMA resources available is limited, the number of
scatter- gather segments used inside the MMC driver can be 8 (passed as
platform data) instead of 16.  On DM355, when the number of scatter-gather
segments was reduced to 8, I saw a performance difference of about
0.25-0.4 Mbytes/sec during write.  Read performance variations were
negligible.

Subject: mmc-omap: add support for 16-bit and 32-bit registers

The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring
a modification of the register addresses in the mmc-omap driver.  To
resolve this, a bit shift is performed on base register addresses, either
by 1 or 2 bits depending on the CPU in use.  This yields the correct
registers for each CPU.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some hosts (e.g.  as found in CNS3xxx SOCs) report wrong value in
CLOCK_BASE capability field, and currently there is no way to force the
SDHCI core to use the platform-provided base clock value.

This patch implements CAP_CLOCK_BASE_BROKEN quirk.  When enabled, the
SDHCI core will always use base clock frequency provided by the platform.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some hosts have an extended SDHCI iomem size, so the driver should
only print errors if the iomem size is less than 0x100.

Improve the suspend and resume callbacks in DaVinci MMC host controller
driver.  Modify the reset status of the contorller and clock during
suspend and resume.  Also migrate the power management callbacks from
platform driver to dev_pm_ops structure.

Tested on DA850/OMAP-L138 EVM.

Subject: mmc: sd: clean up redundant memset

The clearing of mrq via a memset at the top of the for loop in
mmc_wait_for_app_cmd() is not required as mrq is not used and there is
another clearing of mrq just below.  We remove the first memset since if
the initial tests in the for loop fail the memset is not required.

From 88ff82ed4ff048c5548db9313b3de327c91234f8 Mon Sep 17 00:00:00 2001
From: Anders Grahn <anders.grahn@hd-wireless.se>
Date: Wed, 26 May 2010 14:42:01 -0700
Subject: mmc: atmel-mci: Add support for SDIO interrupts

Atmel-mci support for SDIO interrupts.  This adds the enable_sdio_irq()
function and the configuration of sdio irq mask per slot.  With this irq
mask information, we keep the idea of multiple slot per sd/mmc host (not
only A and B).  MMC_CAP_SDIO_IRQ is added according to slot configuration.

A new little function is added to run mmc_signal_sdio_irq() during
interrupt handling routine.

Subject: sdhci: build fix: rename SDHCI I/O accessor functions

Unfortunately some architectures #define their read{b,w,l} and
write{b,w,l} I/O accessors which makes the SDHCI I/O accessor functions of
the same names subject to preprocessing.  This leads to the following
compiler error,

In file included from drivers/mmc/host/sdhci.c:26:
drivers/mmc/host/sdhci.h:318:35: error: macro "writel" passed 3 arguments, but takes just 2

Rename the SDHCI I/O functions so that CONFIG_MMC_SDHCI_IO_ACCESSORS can
be enabled for architectures that implement their read{b,w,l} and
write{b,w,l} functions with macros.

Subject: mmc: s3c6410: add new quirk in sdhci driver and update ADMA
 descriptor build

The s3c6410 sdhci controller does not support the 'End' attribute and NOP
attribute in the same 8-Byte ADMA descriptor.  This patch adds a new quirk
to identify sdhci host contollers with such behaviour.  In addition to
this, for controllers using the new quirk, the last entry in the ADMA
descritor table is marked with the 'End' attribute (instead of using a NOP
descriptor with 'End' attribute).

Subject: omap_hsmmc: improve interrupt synchronisation

The following changes were needed:
	- do not use in_interrupt() because it will not work
	with threaded interrupts

In addition, the following improvements were made:
	- ensure DMA is unmapped only after the final DMA interrupt
	- ensure a request is completed only after the final DMA interrupt
	- disable controller interrupts when a request is not in progress
	- remove the spin-lock protecting the start of a new request from
	an unexpected interrupt because the locking was complicated and
	a 'req_in_progress' flag suffices (since the spin-lock only defers
	the unexpected interrupts anyway)
	- instead use the spin-lock to protect the MMC interrupt handler
	from the DMA interrupt handler
	- remove the semaphore preventing DMA from being started while
	the previous DMA is still in progress - the other changes make that
	impossible, so it is now a BUG_ON condition
	- ensure the controller interrupt status is clear before exiting
	the interrrupt handler

In general, these changes make the code safer but do not fix any specific
bugs so backporting is not necessary.

Subject: mmc: OMAP HS-MMC: convert to dev_pm_ops

Convert PM operations to use dev_pm_ops.  This will facilitate the runtime
PM coversion which will add to dev_pm_ops hooks.

Note that dev_pm_ops version of the suspend hook no longer takes a 'state'
argument.  However, the MMC core function mmc_suspend_host() still takes a
'state' argument, but it is unused, so a dummy state variable was created
to pass to the MMC core.

In the future, the MMC core should be converted to drop this state
argument and the rest of the MMC drivers could be easily converted to
dev_pm_ops as well.

Subject: mmc: remove the "state" argument to mmc_suspend_host()

Even though many mmc host drivers pass a pm_message_t argument to
mmc_suspend_host() that argument isn't used the by MMC core.  As host
drivers are converted to dev_pm_ops they'll have to construct
pm_message_t's (as they won't be passed by the PM subsystem any more) just
to appease the mmc suspend interface.

We might as well just delete the unused paramter.

Subject: sdio: add new function for RAW (Read after Write) operation

SDIO specification allows RAW (Read after Write) operation using
IO_RW_DIRECT command (CMD52) by setting the RAW bit.  This operation is
similar to ordinary read/write commands, except that both write and read
are performed using single command/response pair.  The Linux SDIO layer
already supports this internaly, only external function is missing for
drivers to make use, which is added by this patch.

This type of command is required to implement proper power save mode
support in wl1251 wifi driver.

Android has similar patch for G1 in it's tree for the same reason:

Subject: drivers/mmc/host: use ERR_CAST

Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)).  The former makes more
clear what is the purpose of the operation, which otherwise looks like a
no-op.

The semantic patch that makes this change is as follows:

Subject: gpio: add interrupt handling capability to max732x

Most of the GPIO expanders supported by the max732x driver have interrupt
generation capability by reporting changes on input pins through an INT#
pin.  This patch implements the irq_chip functionnality (edge detection
only).

gpiolib doesn't need to modify the names and I assume most initializers
use string constants that shouldn't be modified anyhow.

Fix a bug I noticed while hacking on the max732x driver for interrupt
support.  According to the datasheets, open-drain pins have to be
configured as output-high (which in that case is actually high impedance)
to be used as input.

The current message, 'not registered' is confusing as it implies it was
not registered with something, whereas printing 'failed to register'
implies it was the gpiochip_add() call that did not work correctly.

Subject: gpiolib: introduce set_debounce method

A few architectures, like OMAP, allow you to set a debouncing time for the
gpio before generating the IRQ.  Teach gpiolib about that.

Mark said:
: This would be generally useful for embedded systems, especially where
: the interrupt concerned is a wake source.  It allows drivers to avoid
: spurious interrupts from noisy sources so if the hardware supports it
: the driver can avoid having to explicitly wait for the signal to become
: stable and software has to cope with fewer events.  We've lived without
: it for quite some time, though.

David said:
: I looked at adding debounce support to the generic GPIO calls (and thus
: gpiolib) some time back, but decided against it.  I forget why at this
: time (check list archives) but it wasn't because of lack of utility in
: certain contexts.
:
: One thing to watch out for is just how variable the hardware capabilities
: are.  Atmel GPIOs have something like a fixed number of 32K clock cycles
: for debounce, twl4030 had something odd, OMAPs were more like the Atmel
: chips but with a different clock.  In some cases debouncing had to be
: ganged, not per-GPIO.  And so forth.

The ipmi spec provides an ordering for si discovery.  Change the driver to
match, with the exception of preferring smbios to SPMI as HPs (at least)
contain accurate information in the former but not the latter.

Subject: ipmi: reduce polling when interrupts are available

If we're not currently in the middle of a transaction, and if we have
interrupts, there's no real reason to poll the controller more frequently
than the core IPMI code does.  Set the interrupt_disabled flag
appropriately as the interrupt state changes, and make the timeout code
reset itself only if the transaction is incomplete or we have no
interrupts.

Subject: ipmi: attempt to register multiple SIs of the same type

Some odd systems may have multiple BMCs, and we want to be able to support
them.  Let's make the assumption that if a system legitimately has
multiple BMCs then each BMC's SI will be of the same type, and also that
we won't see multiple SIs of the same type unless we have multiple BMCs.
If these hold true then we should register all SIs of the same type.

Subject: ipmi: change timeout and event poll to one second

The timeouts in IPMI are in the 1-5 second range in message handling, so a
1 second timeout is a reasonable thing to do.  This should help with
reducing power consumption on idle systems.

Convert PNP patch (git 9e368fa011d4e0aa050db348d69514900520e40b) to
maintain a pointer to a PNP device, 'pnp_dev', instead of the ACPI device,
'acpi_dev', that is currently being tracked with PNP based IPMI device
discovery.

Update core IPMI driver printk()'s with dev_printk(), and its constructs,
to provide additional device topology information.

An example of the additional device topology for a PNP device -

  ipmi_si 00:02: [io  0x0ca2-0x0ca3] regsize 1 spacing 1 irq 0
  ipmi_si 00:02: Found new BMC (man_id: 0x00000b, prod_id: 0x0000, ...
  ipmi_si 00:02: IPMI kcs interface initialized

and for a PCI device -
  ipmi_si 0000:01:04.6: probing via PCI
  ipmi_si 0000:01:04.6: PCI INT A -> GSI 21 (level, low) -> IRQ 21

Subject: ipmi: handle run_to_completion properly in deliver_recv_msg()

If run_to_completion flag is set, it means that we are running in a
single-threaded mode, and thus no locks are held.

This fixes a deadlock when IPMI notifier is being called during panic.

Subject: char drivers: RAM oops/panic logger

Ramoops, like mtdoops, can log oops/panic information but in RAM.  It can
be used with persistent RAM for systems without flash support.  In
addition, for this systems, with this driver, it's no more needed add to
the kernel the mtd subsystem with advantage in footprint.

It can be used in a very easy way with persistent RAM for systems without
flash support.  For these systems, with this driver, it is no longer
required to cinlude mtd subsystem with an advantage in footprint.  In
addition, you can save flash space and store this information only in RAM.

Subject: drivers/char/applicom.c: use memdup_user

Use memdup_user when user data is immediately copied into the
allocated region.

The semantic patch that makes this change is as follows:

Subject: rapidio: add IDT CPS/TSI switches

Extentions to RapidIO switch support:

1. modify switch route operation declarations to allow using single
   switch-specific file for family of switches that share the same route
   table operations.

2. add standard route table operations for switches that that support
   route table manipulation registers as defined in the Rev.1.3 of RapidIO
   specification.

3. add clear-route-table operation for switches

4. add CPSxx and TSIxxx families of RapidIO switches

Subject: rapidio: add switch locking during discovery

Add switch access locking during RapidIO discovery.  Access lock is
required when reading switch routing table contents due to indexed
mechanism of RT addressing.

Subject: Staging: saa7134-go7007: replace dma_sync_single with
 dma_sync_single_for_cpu

dma_sync_single() is deprecated and will be removed soon.

No functional change since dma_sync_single is the wrapper of
dma_sync_single_for_cpu.

saa7134-go7007.c is commented out but anyway let's replace it.

Subject: lktdm: add support for hardlockup, softlockup and hung task crashes

This adds three new types of kernel "crashes" in the lkdtm driver to
trigger hardlockups, softlockups and task hung states at will.

The first two are useful to test the new generic lockup detector and check
its further regressions.  The latter one is a bonus to check the hung task
detector regressions even though it's not currently in rework.

osst_read()/osst_write() modify file->f_pos directly instead of the ppos
given to them.  The VFS later updates the file->f_pos and overwrites it
with the value of ppos.

__os_scsi_tape_open() suggests that llseek() doesn't work: "We really want
to do nonseekable_open(inode, filp); here, but some versions of tar
incorrectly call lseek on tapes and bail out if that fails.  So we
disallow pread() and pwrite(), but permit lseeks."

Instead of using the fallback default_llseek() the driver should use
noop_llseek() which leaves the file->f_pos untouched but succeeds.

+What:		/sys/firmware/sfi/tables/
+Date:		May 2010
+Contact:	Len Brown <lenb@kernel.org>
+Description:
+		SFI defines a number of small static memory tables
+		so the kernel can get platform information from firmware.
+
+		The tables are defined in the latest SFI specification:
+		http://simplefirmware.org/documentation
+
+		While the tables are used by the kernel, user-space
+		can observe them this way:
+
+		# cd /sys/firmware/sfi/tables
+		# cat $TABLENAME > $TABLENAME.bin

Subject: hwmon: (asus_atk0110) Don't load if ACPI resources aren't enforced

When the user passes the kernel parameter acpi_enforce_resources=lax,
the ACPI resources are no longer protected, so a native driver can
make use of them. In that case, we do not want the asus_atk0110 to be
loaded. Unfortunately, this driver loads automatically due to its
MODULE_DEVICE_TABLE, so the user ends up with two drivers loaded for
the same device - this is bad.

So I suggest that we prevent the asus_atk0110 driver from loading if
acpi_enforce_resources=lax.

Subject: hwmon: (lm90) Use programmed update rate

The lm90 driver programs the sensor chip to update its readings at 2 Hz
(500 ms between readings). However, the driver only does reads from the
chip at intervals of 2 * HZ (2000 ms between readings). Change the driver
update rate to the programmed update rate.

Subject: hwmon: (applesmc) Add temperature sensor labels to sysfs interface

The Apple SMC uses a systematic labeling scheme for the hardware
temperature sensors. This scheme is currently hidden from
userland. Since the sensor set, and consequently the numbering,
differs between models, an extensive database of configurations is
required for an application such as fan control. This patch adds the
SMC labels to the hwmon sysfs interface, allowing applications to use
the sensors more intelligibly.

Subject: hwmon: EMC1403 thermal sensor support

Provides support for the EMC1403 thermal sensor. Only reporting of values
is supported. The various Moorestown specific extras to do with thermal
alerts and the like are not in this version of the driver.

Considerably edited and tidied up by Alan Cox, plus fixes and detection
bits from Jean Delvare.

Subject: hwmon: Driver for TI TMP102 temperature sensor

Driver for the TI TMP102.

The TI TMP102 is similar to the LM75.  It differs from the LM75 by
having a 16-bit conf register and the temp registers have a minimum
resolution of 12 bits; the extended conf register can select 13-bit
resolution (which this driver does) and also change the update rate
(which this driver currently doesn't use).

[JD: Fix tmp102_exit tag, must be __exit, not __init.]

+Description
+-----------
+
+The Texas Instruments TMP102 implements one temperature sensor.  Limits can be
+set through the Overtemperature Shutdown register and Hysteresis register.  The
+sensor is accurate to 0.5 degrees over the range of -25 to +85 C, and to 1.0
+degrees from -40 to +125 C. Resolution of the sensor is 0.0625 degree.  The
+operating temperature has a minimum of -55 C and a maximum of +150 C.
+
+The TMP102 has a programmable update rate that can select between 8, 4, 1, and
+0.5 Hz. (Currently the driver only supports the default of 4 Hz).
+
+The driver provides the common sysfs-interface for temperatures (see
+/Documentation/hwmon/sysfs-interface under Temperatures).

Subject: hwmon: (tmp102) Various fixes

Fixes from my driver review:
http://lists.lm-sensors.org/pipermail/lm-sensors/2010-March/028051.html

Only the small changes are in there, more important changes will come
later separately as time permits.

* Drop the remnants of the now gone detect function
* The TMP102 has no known compatible chip
* Include the right header files
* Clarify why byte swapping of register values is needed
* Strip resolution info bit from temperature register value
* Set cache lifetime to 1/3 second
* Don't arbitrarily reject limit values; clamp as needed
* Make limit writing unconditional
* Don't check for transaction types the driver doesn't use
* Properly check for error when setting configuration
* Report error on failed probe
* Make the driver load automatically where needed
* Various other minor fixes

 The Texas Instruments TMP102 implements one temperature sensor.  Limits can be
 set through the Overtemperature Shutdown register and Hysteresis register.  The
-sensor is accurate to 0.5 degrees over the range of -25 to +85 C, and to 1.0
-degrees from -40 to +125 C. Resolution of the sensor is 0.0625 degree.  The
+sensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0
+degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree.  The
 operating temperature has a minimum of -55 C and a maximum of +150 C.
 
 The TMP102 has a programmable update rate that can select between 8, 4, 1, and
 0.5 Hz. (Currently the driver only supports the default of 4 Hz).
 
 The driver provides the common sysfs-interface for temperatures (see

Subject: hwmon: (tmp102) Fix suspend and resume functions

Suspend and resume functions shouldn't overwrite the configuration
register. They should only alter the one bit they have to touch.

Also don't assume that register reads and writes always succeed.
Handle errors properly, shall they happen.

loaded. Leave it running otherwise.

Also restore the device configuration if probe failed, to not leave

Subject: hwmon: (ltc4245) Read only one GPIO pin

Read only one of the GPIO pins as an analog voltage. The ADC can be
switched to a different GPIO pin at runtime, but this is not supported.

Previously, this driver would report the analog voltage of the currently
selected GPIO pin as all three GPIO voltages: in9_input, in10_input and
in11_input.

Subject: IB/qib: Remove DCA support until feature is finished

The DCA code was left over from internal development to test the
hardware feature and allow performance testing.  The results were
mixed and will require some additional work to make full use of the
feature.  Therefore, it is being removed for now.

Subject: mfd: Add in XIIC to some configurations of timberdale
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds in the Xilinx I2C bus driver to some of the
configurations of the timberdale MFD.

It provides the I2C devices to the XIIC via platform data in a
similar way as done to the ocores driver.

Subject: mfd: Add support for the RDC321x southbridge

This patch adds a new MFD driver for the RDC321x southbridge. This southbridge
is always present in the RDC321x System-on-a-Chip and provides access to some
GPIOs as well as a watchdog. Access to these two functions is done using the
southbridge PCI device configuration space.

Subject: watchdog: Convert rdc321x_wdt to use southbridge pci device

The RDC321x MFD southbridge driver will pass a reference to the
southbridge PCI device which should be used by the watchdog driver for its
operations.  This patch converts the watchdog driver to use the pci_dev
pointer and make use of the base register resource which is passed along
with the platform device.

I'm pretty sure that it should be + 1 here.  It's an off by one, because

Subject: mfd: Section cleanup of 88pm860x driver

This patch fixes three section mismatches.

WARNING: drivers/mfd/88pm860x.o(.text+0x12): Section mismatch in
reference from the function pm860x_device_exit() to the function
.devexit.text:device_irq_exit()
The function pm860x_device_exit() references a function in an exit
section.
Often the function device_irq_exit() has valid usage outside the exit
section
and the fix is to remove the __devexit annotation of device_irq_exit.

WARNING: drivers/mfd/88pm860x.o(.text+0xb0): Section mismatch in
reference from the function pm860x_device_init() to the function
.devinit.text:device_8606_init()
The function pm860x_device_init() references
the function __devinit device_8606_init().
This is often because pm860x_device_init lacks a __devinit
annotation or the annotation of device_8606_init is wrong.

WARNING: drivers/mfd/88pm860x.o(.text+0xbe): Section mismatch in
reference from the function pm860x_device_init() to the function
.devinit.text:device_8607_init()
The function pm860x_device_init() references
the function __devinit device_8607_init().
This is often because pm860x_device_init lacks a __devinit
annotation or the annotation of device_8607_init is wrong.

Subject: gpio: Add support for Janz VMOD-TTL Digital IO module

The Janz VMOD-TTL is a MODULbus daughterboard which fits onto any MODULbus
carrier board. It essentially consists of some various logic and a Zilog
Z8536 CIO Counter/Timer and Parallel IO Unit.

The board must be physically configured with jumpers to enable a user to
drive output signals. I am only interested in outputs, so I have made this
driver as simple as possible. It only supports a very minimal subset of the
features provided by the Z8536 chip.

From 7cc1392aabc31d2af9bd3cc5febbd91977452181 Mon Sep 17 00:00:00 2001
From: Mark Brown <broonie@opensource.wolfsonmicro.com>
Date: Fri, 2 Apr 2010 16:31:03 +0100
Subject: mfd: Improve WM831x AUXADC completion handling

Currently completion of WM831x AUXADC conversions is monitored by
checking for convertor enable. Due to the mechanism used to ensure
data corruption is avoided when reading AUXADC data there may under
heavy I/O be a window where this bit has cleared but the conversion
results have not been updated. Data availability is only guaranteed
after the AUXADC data interrupt has been asserted.

Avoid this by always using the interrupt to detect completion. If the
chip IRQ is not set up then we poll the IRQ status register for up to
5ms. If it is set up then we rely on the data done interrupt with a
vastly increased timeout, failing the conversion if the interrupt is
not generated.

This also saves a register read when using interrupts.

Add mfd structure which refrences sub-driver initialization data. For example,
for a giving hardware implementation, the voltage regulator sub-driver
initialization data provides the mapping betten a voltage regulator and what
the output voltage is being used for.

From 752599667048898b6969e06e4637f906b04ec752 Mon Sep 17 00:00:00 2001
From: Todd Fischer <todd.fischer@ridgerun.com>

Subject: input: Touchscreen driver for TPS6507x

Add touch screen input driver for TPS6507x family of multi-function
chips.  Uses the TPS6507x MFD driver.  No interrupt support due to
testing limitations of current hardware.

Subject: mfd: Initialise WM831x IRQ masks on chip even if interrupts not in
 use

Ensure that the hardware has interrupts masked if we are not using
the interrupt controller on the WM831x by initialising the masks
before we check for the setup data required for the IRQ line. This
avoids signalling an unused IRQ line and improves the robustness
of checks that the IRQ is in use.

Subject: mfd: Ensure WM831x charger interrupts are acknowledged when
 suspending

The charger interrupts on the WM831x are unconditionally a wake source
for the system. If the power driver is not able to monitor them (for
example, due to the IRQ line not having been wired up on the system)
then any charger interrupt will prevent the system suspending for any
meaningful amount of time since nothing will ack them.

Avoid this issue by manually acknowledging these interrupts when we
suspend the WM831x core device if they are masked. If software is
actually using the interrupts then they will be unmasked and this
change will have no effect.

Subject: mfd: Fix error in wm8400 reg cache access check

Accessing num_reg elements in the interval [reg .. reg+num_regs)
is permitted if (reg+numregs <= array size), so barf when that
excluded upper bound is > array size. The prior -1 would give
access to one too many elements.

Subject: mfd: Delay to mask tsc irq in max8925

There're two IRQ pins output from MAX8925. One is PMIC interrupt, the other
is TSC interrupt. But they're sharing one irq chip.

After initializing MAX8925 interrupts, unexpected TSC interrupt may occur and
it can't be cleared if touch driver isn't loaded.

Now move the operation of masking TSC interrupt behind requesting PMIC
interrupt. If touch driver isn't loaded, this interrupt is always masked.

Subject: mfd: Renamed ab3100.h to abx500.h

The goal here is to make way for a more general interface for the
analog baseband chips ab3100 ab3550 ab550 and future chips.

This patch have been divided into two parts since both changing name
and content of a file is not recommended in git.

Subject: mfd: AB3100 register access change to abx500 API

The interface for the AB3100 is changed to make way for the
ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson
Analog Baseband chips. The register access functions are moved
out to a separate struct abx500_ops. In this way the interface
is moved from the implementation and the sub functionality drivers
can keep their interface intact when chip infrastructure and
communication mechanisms changes. We also define the AB3550
device IDs and the AB3550 platform data struct and convert
the catenated 32bit event to an array of 3 x 8bits.

Subject: mfd: AB3550 core driver

This adds a core driver for the AB3550 mixed-signal circuit
found in the ST-Ericsson U300 platforms. This driver
is a singleton proxy for all access to the AB3550 sub
functionality drivers which can be added on top of this one:
RTC, regulators, battery and system power control, vibrator,
LEDs and an ALSA codec.

Subject: mfd: pcf50633-adc: Fix potential race in pcf50633_adc_sync_read

Currently it's not guaranteed that request struct is not already freed when
reading from it. Fix this by moving synced request related fields from the
pcf50633_adc_request struct to its own struct and store it on the functions
stack.

From 8deca39e5caf7a20fc3786548dc9bfb7f0ae14b6 Mon Sep 17 00:00:00 2001
From: Florian Fainelli <florian@openwrt.org>
Date: Sat, 15 May 2010 22:58:27 +0200
Subject: mfd: Change rdc321x resources flags to IORESOURCE_IO

The rdc321x southbridge PCI device has no MEM PCI resources that we could
pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the
mem_base argument that we set to NULL. Changing the resources passed to
our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use
those resources as offsets to the PCI configuration space base address of
the southbridge device this is also more adequate.

Subject: mfd: New AB8500 driver

Add a new driver to support the AB8500 Power Management chip, replacing
the current AB4500.  The new driver replaces the old one, instead of an
incremental modification, because this is a substantial overhaul
including:

 - Split of the driver into -core and -spi portions, to allow another
   interface layer to be added

 - Addition of interrupt support

 - Switch to MFD core API for handling subdevices

 - Simplification of the APIs to remove a redundant block parameter

 - Rename of the APIs and macros from ab4500_* to ab8500_*

 - Rename of the files from ab4500* to ab8500*

 - Change of the driver name from ab4500 to ab8500

Subject: mfd: Remove unneeded and dangerous clearing of clientdata

Unlike real i2c-devices which get detached from the driver, dummy-devices
get truly unregistered. So, there has never been a need to clear the
clientdata because the device will go away anyhow. For the occasions fixed
here, clearing clientdata was even dangerous as the structure was freed
already.

Subject: mfd: Storage class for timberdale should be before const qualifier

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

Subject: cpuidle: make cpuidle_curr_driver static

cpuidle_register_driver() sets cpuidle_curr_driver
cpuidle_unregister_driver() clears cpuidle_curr_driver

We should't expose cpuidle_curr_driver to
potential modification except via these interfaces.
So make it static and create cpuidle_get_driver() to observe it.

Subject: ACPI: allow a native cpuidle driver to displace ACPI

The ACPI driver would fail probe when it found that
another driver had previously registered with cpuidle.

But this is a natural situation, as a native hardware
cpuidle driver should be able to bind instead of ACPI,
and the ACPI processor driver should be able to handle
yielding control of C-states while still handling
P-states and T-states.

Add a KERN_DEBUG line showing when acpi_idle
does successfully register.

Subject: acpi_pad: uses MONITOR/MWAIT, so it doesn't need to clear TS_POLLING

api_pad exclusively uses MONITOR/MWAIT to sleep in idle,
so it does not need the wakeup IPI during idle sleep
that is provoked by clearing TS_POLLING.

Subject: drm/nouveau: allow cursor image and position to survive suspend

- This isn't triggered yet on a normal kernel, because it still does a VT
switch, but it seemed like a good idea to fix this now.

Subject: drm/nouveau: fix POST detection for certain chipsets

We totally fail at detecting un-POSTed chipsets prior to G80.  This commit
changes the pre-G80 POST detection to read the programmed horizontal total
from CRTC 0, and assume the card isn't POSTed if it's 0.

NVIDIA use some other heuristics more similar to what we do on G80, but I
wasted quite a long time trying to figure out the exact specifics of what
they do so we can try this for a bit instead.

It was once assumed that all G8x had dual-link TMDS everywhere, this isn't
actually the case - especially considering passive DP->DVI converters and
some HDMI connectors only support single-link.

Subject: drm/nouveau: fix dual-link displays when plugged into single-link
 outputs

When selecting the native mode for a display we weren't taking into account
whether or not it was actually supported on that particular output.

This patch modifies our native mode selection to run all modes through
mode_valid() first.

We need to zero context memory on 5709 in the function cnic_init_context().
Without this, iscsid restart on 5709 will not work because of stale data.
TX context blocks should not be initialized by cnic_init_context() because
of the special remapping on 5709.

Update version to 2.1.2.

Subject: netdev/fec: fix ifconfig eth0 down hang issue

BugLink: http://bugs.launchpad.net/bugs/559065

In fec open/close function, we need to use phy_connect and phy_disconnect
operation before we start/stop phy. Otherwise it will cause system hang.

Only call fec_enet_mii_probe() in open function, because the first open
action will cause NULL pointer error.

Subject: ath9k: Fix ath_print in xmit for hardware reset.

ath_print in xmit.c should say "Reseting hardware"
instead of Resetting HAL!(since HAL is being fazed out).
dmesg shows:
[ 8660.899624] ath: Failed to stop TX DMA in 100 msec after killing last frame
[ 8660.899676] ath: Unable to stop TxDMA. Reset HAL!

Subject: ath9k: Fix bug in the way "bf_tx_aborted" of struct ath_buf is used

This bug was introduced by the following commit

	Author: Vasanthakumar Thiagarajan <vasanth@atheros.com>
	Date:   Thu Apr 15 17:38:46 2010 -0400

	ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose

Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(),
this may result in a rate scaling with wrong feedback (number
of unacked frames in this case). It is the last one in the chain
of buffers for an aggregate frame that should be checked.

Also it misses the initialization of this field in the buffer,
this may lead to a situation where we stop the sw retransmission
of failed subframes associated to this buffer.

Delay taking the mutex until we need to and ensure that we hold the
spinlock when resetting unpin_work on the error path. Also defer the
debugging print messages until after we have released the spinlock.

Subject: drm/i915: Remove spurious warning "Failure to install fence"

This particular warning is harmless as we emit during the normal
pinning process where the batch buffer requires more fences than is
available without eviction. Only if we fail to evict enough fences does
this become a problem, so include the requested number of fences in the
ultimate *error* message.

v2: Remember to compile test even trial patches to remove warnings.

Subject: ACPI: acpi_idle: touch TS_POLLING only in the non-MWAIT case

commit d306ebc28649b89877a22158fe0076f06cc46f60
(ACPI: Be in TS_POLLING state during mwait based C-state entry)
fixed an important power & performance issue where ACPI c2 and c3 C-states
were clearing TS_POLLING even when using MWAIT (ACPI_STATE_FFH).
That bug had been causing us to receive redundant scheduling interrups
when we had already been woken up by MONITOR/MWAIT.

Following up on that...

In the MWAIT case, we don't have to subsequently
check need_resched(), as that c heck was there
for the TS_POLLING-clearing case.

Note that not only does the cpuidle calling function
already check need_resched() before calling us, the
low-level entry into monitor/mwait calls it twice --
guaranteeing that a write to the trigger address
can not go un-noticed.

Also, in this case, we don't have to set TS_POLLING
when we wake, because we never cleared it.

Subject: drm/i915: Avoid moving from CPU domain during pwrite

We can avoid an early clflush when pwriting if we use the current CPU
write domain rather than moving the object to the GTT domain for the
purposes of the pwrite. This has the advantage of not flushing the
presumably hot data that we want to upload into the bo, and of ascribing
the clflush to the execution when profiling.

As we do not have a requirement to be atomic and avoid sleeping whilst
performing the slow copy for shmem based pread and pwrite, we can use
kmap instead, thus simplifying the code.

Subject: drm/i915: Fix up address spaces in slow_kernel_write()

Since we now get_user_pages() outside of the mutex prior to performing
the copy, we kmap() the page inside the copy routine and so need to
perform an ordinary memcpy() and not copy_from_user().

Subject: drm/i915: Fix PIPE_CONTROL command on Sandybridge

Sandybridge(Gen6) has new format for PIPE_CONTROL command,
the flush and post-op control are in dword 1 now. This
changes command length field for difference between Ironlake
and Sandybridge.

I tried to test this with noop request and issue PIPE_CONTROL
command for each sequence and track notify interrupts, which
seems work fine. Hopefully we don't need workaround like on
Ironlake for Sandybridge.

Subject: intel_idle: native hardware cpuidle driver for latest Intel
 processors

This EXPERIMENTAL driver supersedes acpi_idle on
Intel Atom Processors, Intel Core i3/i5/i7 Processors
and associated Intel Xeon processors.

It does not support the Intel Core2 processor or earlier.

For kernels configured with ACPI, CONFIG_INTEL_IDLE=y
allows intel_idle to probe before the ACPI processor driver.
Booting with "intel_idle.max_cstate=0" disables intel_idle
and the system will fall back on ACPI's "acpi_idle".

Typical Linux distributions load ACPI processor module early,
making CONFIG_INTEL_IDLE=m not easily useful on ACPI platforms.

intel_idle probes all processors at module_init time.
Processors that are hot-added later will be limited
to using C1 in idle.

Subject: ACPI: Minor cleanup eliminating redundant PMTIMER_TICKS to NS
 conversion

acpi_enter_[simple,bm] does
idle timing in ns, convert it to timeval, then to us, then to
pmtimer_ticks and then back to ns.

This patch changes things to
idle timing in ns, convert it to us, and then to pmtimer_ticks.

Just saves an imul along this path, but makes the code cleaner.

Subject: ACPI: Don't let acpi_pad needlessly mark TSC unstable

acpi pad driver kind of aggressively marks TSC as unstable at init
time, on mwait capable and non X86_FEATURE_NONSTOP_TSC systems. This is
irrespective of whether pad driver is ever going to be used on the
system or deep C-states are supported/used. This will affect every user
who just happens to compile in (or get a kernel version which
compiles in) acpi pad driver.

Move mark_tsc_unstable() out of init to the actual idle invocation path
of the pad driver.

There is also another bug/missing_feature in the code that it does not
support 'always running apic timer' and switches to broadcast mode
unconditionally. Shaohua, can you take a look at that please.

Date: Fri, 9 Apr 2010 01:39:40 +0200
Subject: ACPI / EC / PM: Fix race between EC transactions and system suspend

There still is a race that may result in suspending the system in
the middle of an EC transaction in progress, which leads to problems
(like the kernel thinking that the ACPI global lock is held during
resume while in fact it's not).

To remove the race condition, modify the ACPI platform suspend and
hibernate callbacks so that EC transactions are blocked right after
executing the _PTS global control method and are allowed to happen
again right after the low-level wakeup.

Introduce acpi_pm_freeze() that will disable GPEs, wait until the
event queues are empty and block EC transactions.  Use it wherever
GPEs are disabled in preparation for switching local interrupts off.
Introduce acpi_pm_thaw() that will allow EC transactions to happen
again and enable runtime GPEs.  Use it to balance acpi_pm_freeze()
wherever necessary.

In addition to that use acpi_ec_resume_transactions_early() to
unblock EC transactions as early as reasonably possible during
resume.  Also unblock EC transactions in acpi_hibernation_finish()
and in the analogous suspend routine to make sure that the EC
transactions are enabled in all error paths.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=14668

Subject: ACPI / EC / PM: Fix names of functions that block/unblock EC
 transactions

The names of the functions used for blocking/unblocking EC
transactions during suspend/hibernation suggest that the transactions
are suspended and resumed by them, while in fact they are disabled
and enabled.  Rename the functions (and the flag used by them) to
better reflect what they really do.

Subject: fs_enet: Adjust BDs after tx error

This patch fixes an occasional transmit lockup in the mac-fcc which
occurs after a tx error.  The test scenario had the local port set
to autoneg and the other end fixed at 100FD, resulting in a large
number of late collisions.

According to the MPC8280RM 30.10.1.3 (also 8272RM 29.10.1.3), after
a tx error occurs, TBPTR may sometimes point beyond BDs still marked
as ready.  This patch walks back through the BDs and points TBPTR to
the earliest one marked as ready.

Tested on a custom board with a MPC8280.

Add a spin_unlock missing on the error path.  The return value of write_reg

Subject: Input: s3c2410_ts - fix build error due to ADC Kconfig rename

The name of the Kconfig symbol for the ADC has changed as a result of
application to more SoCs but the select statement has not been updated,
causing linker failures as the ADC core has not been built.

Subject: Input: s3c2410_ts - tone down logging

The S3C touchscreen driver is logging at LOG_INFO on every stylus up
event which spams the console needlessly.  Reduce the priority of the
message to debug level for some peace and quiet.

Subject: drm/vmwgfx: Add kernel throttling support. Bump minor.

The throttle_us member in the execbuf argument is now honored.
If the member is 0, no waiting for lag will occur, which
guarantees backwards compatibility with well-behaved clients.

Subject: drm/vmwgfx: Reserve first part of VRAM for framebuffer.

The host may be touching this part of VRAM at modesetting,
even if we never use it ourselves, since we blit screen updates from 3D
surfaces. Make sure no DMA buffers are placed in this part of VRAM.

V2: Fix an error check in vmw_surface_dmabuf_pin().

Subject: drm/ttm: Fix cached TTM page allocation.

This patch fixes a regression introduced with the pool page allocator
in the event that there are no highmem pages (for example x86_64),
in which case cached page allocation would fail.

Subject: drm/nouveau: attempt to get bios from ACPI v3

Some of the laptops with the switchable graphics, seem to not post the secondary GPU at all, and we can't find a copy of the BIOS anywhere except in the ACPI rom retrieval.

This adds support for ACPI ROM retrieval to nouveau.

Subject: V4L/DVB: bw-qcam: convert to V4L2

Note: due to lack of hardware I was not able to test this conversion.
But it is pretty straightforward, so I do not expect any problems.

From d71964fb9731412ce1f86cd7d9b71f1f94a04b0d Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Mon, 10 May 2010 03:55:25 -0300
Subject: V4L/DVB: c-qcam: convert to V4L2

Note: due to lack of hardware this conversion is untested.
However, it is pretty straightforward so I do not expect any problems.

Subject: V4L/DVB: pvrusb2: Fix kernel oops at device unregistration

pvrusb2: Fix oops caused by touching deleted memory after
unregistration.  This bug was introduced when we had started using
video_device_node_name() - that function was being called potentially
after the underlying structure (referenced by that function) had been
deleted.  The fix rearranges things slightly so that the function is
called before destruction takes place.

Subject: V4L/DVB: pvrusb2: Fix kernel oops on device tear-down

pvrusb2: Delete sysfs class device as the _very_ last step, after
we're sure that all driver contexts have gone away first.  This is
important because it appears that there isn't any protection from a
struct device instance reference a deleted struct class instance.  The
assumption in the kernel code appears to be that the class instance is
assumed to be around for the life of the device.  So we can't let the
class instance go away until all referencing device instances are
gone; this is ensured by delaying removal of the class instance until
after the driver contexts have all gone away.  This bug has been
present for a very long time but it didn't apparently become malignant
until recently (probably because of other changes in the kernel).

Subject: V4L/DVB: mt9v011: add enum/try/s_mbus_fmt support

Note that this driver is only used by em28xx and that em28xx does not
actually call the enum/try/s_fmt ops of mt9v011. So these functions
have never been tested.

And in fact the driver really implements cropping instead of scaling. So it
seems to be doing the wrong thing :-(

Subject: V4L/DVB: v4l2-subdev.h: fix enum_mbus_fmt prototype

enum_mbus_fmt received an index argument that was defined as an int instead
of an unsigned int. This is now fixed. This had the knock-on effect that the
index argument in the callback get_formats in soc_camera.h also had to be
changed to unsigned int.

Subject: V4L/DVB: tvp514x: do NOT change the std as a side effect

Several calls (try_fmt, g_parm among others) changed the current standard
as a side effect of that call. But the standard may only be changed by s_std.

Subject: V4L/DVB: tvp514x: there is only one supported format, so simplify the
 code

Get rid of unnecessary code since this driver supports only one
pixel format. Removing this code will make the transition to the
mbus API easier as well.

Subject: V4L/DVB: saa7134: add support for Avermedia M733A

This change adds support for Avermedia M733A. The original version for
linux 2.6.31 was sent to me from Avermedia, original author is unknown.
I ported it to current kernels, expanded and fixed key code handling for
RM-K6 remote control, and added an additional pci id also supported.

Subject: V4L/DVB: FusionHDTV: Use quick reads for I2C IR device probing

IR support on FusionHDTV cards is broken since kernel 2.6.31. One side
effect of the switch to the standard binding model for IR I2C devices
was to let i2c-core do the probing instead of the ir-kbd-i2c driver.
There is a slight difference between the two probe methods: i2c-core
uses 0-byte writes, while the ir-kbd-i2c was using 0-byte reads. As
some IR I2C devices only support reads, the new probe method fails to
detect them.

For now, revert to letting the driver do the probe, using 0-byte
reads. In the future, i2c-core will be extended to let callers of
i2c_new_probed_device() provide a custom probing function.

Subject: V4L/DVB: IR/imon: add auto-config for 0xffdc rf device

Add auto-config support for iMON 2.4G LT RF device, based on
debug output from Giulio Amodeo in Red Hat bugzilla #572288.

Also flips the switch on only setting up the rf associate sysfs
attr only if we think we're looking at an RF device, vs. previously,
setting up the attr for all 0xffdc devices, so its possible (but a bit
unlikely) there's another iMON RF device we'll have to fix up.

Nb: should be applied after "IR/imon: clean up usage of bools", or there
will be a slight contextual mismatch.

Subject: V4L/DVB: video/saa7134: change dprintk() to i2cdprintk()

The problem is that dprintk() dereferences "dev" which is null here.
The i2cdprintk() uses "ir" so that's OK.

Also Jean Delvare pointed out a typo in the comment so we may as well
fix that.

Fix ULE decapsulation bug when less than 4 bytes of ULE SNDU is packed
into the remaining bytes of a MPEG2-TS frame

ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation
code has a bug that incorrectly treats ULE SNDU packed into the
remaining 2 or 3 bytes of a MPEG2-TS frame as having invalid pointer
field on the subsequent MPEG2-TS frame.

Subject: virtio-net: pass gfp to add_buf

virtio-net bounces buffer allocations off to
a thread if it can't allocate buffers from the atomic
pool. However, if posting buffers still requires atomic
buffers, this is unlikely to succeed.
Fix by passing in the proper gfp_t parameter.

He is right, we actually want to use an even val with TCP_QUICKACK.

Subject: drbd: need to set socket bufsize early to take effect

quoting tcp(7):
    On individual connections, the socket buffer size must be set prior to the
    listen(2) or connect(2) calls in order to have it take effect.

This adds a wrapper to do so, and uses it appropriately.
Improves performance in certain situations.

Note that because we cannot easily determine which socket will be
"meta" and wich "data" (bulk) socket, we adjust both sockets.
Previously, DRBD only adjusted the bufsizes of the "data" socket.

Thanks again to Eduard.Guzovsky@stratus.com.

Subject: drbd: improve usage of MSG_MORE

It seems to improve performance if we allow the "p_data" header in its
own frame (no MSG_MORE), but sendpage all but the last page with MSG_MORE.
This is also in preparation of a later zero copy receive implementation.

Suggested by Eduard.Guzovsky@stratus.com on drbd-dev.

Subject: drbd: fix hang on local read errors while disconnected

"canceled" w_read_retry_remote never completed, if they have been
canceled after drbd_disconnect connection teardown cleanup has already
run (or we are currently not connected anyways).

Fixed by not queueing a remote retry if we already know it won't work
(pdsk not uptodate), and cleanup ourselves on "cancel", in case we hit a
race with drbd_disconnect.

Subject: ath5k: wake queues on reset

We can wake all queues after a chip reset since everything should be set up and
we are ready to transmit. If we don't do that we might end up starting up with
stopped queues, not beeing able to transmit. (This started to happen after
"ath5k: clean up queue manipulation" but since periodic calibration also
stopped and started the queues this effect was hidden most of the time).

This way we can also get rid of the superfluous ath5k_reset_wake() function.

Subject: Input: tps6507x-ts - a couple work queue cleanups

1) Use msecs_to_jiffies() instead of calculating by hand.
2) Call cancel_delayed_work_sync() instead of cancel_delayed_work()
   followed by a separate flush_workqueue().
3) Remove the "tsc->wq = 0;"  Sparse complains about that because
   tsc->wq is a pointer, not an int.  It's not needed because we just
   free the pointer anyway.

Subject: usb: gadget: m66592-udc pio to mmio accessor conversion.

m66592-udc is erroneously using PIO routines on MMIO registers, which
presently blows up for any platform that elects to either override or do
away with PIO routines. This managed to work for the common cases since
the PIO routines were simply wrapped to their MMIO counterparts. This
switches over to using the MMIO routines directly, and enables us to kill
off a lot of superfluous casting in the process.

Subject: usb: gadget: r8a66597-udc pio to mmio accessor conversion.

r8a66597-udc is erroneously using PIO routines on MMIO registers, which
presently blows up for any platform that elects to either override or do
away with PIO routines. This managed to work for the common cases since
the PIO routines were simply wrapped to their MMIO counterparts. This
switches over to using the MMIO routines directly, and enables us to kill
off a lot of superfluous casting in the process.

Subject: agp/uninorth: Fix oops caused by flushing too much

This fixes a sporadic oops at boot on G5 Power Macs.  The table_end
variable has the address of the last byte of the table.  Adding on
PAGE_SIZE means we flush too much, and if the page after the table
is not mapped for any reason, the kernel will oops.  Instead we add
on 1 because flush_dcache_range() interprets its second argument as
the first byte past the range to be flushed.

Subject: powerpc/macio: Fix probing of macio devices by using the right of
 match table

Grant patches added an of mach table to struct device_driver. However,
while he changed the macio device code to use that, he left the match
table pointer in struct macio_driver and didn't update drivers to use
the "new" one, thus breaking the probing.

This completes the change by moving all drivers to setup the "new"
one, removing all traces of the old one, and while at it (since it
changes the exact same locations), I also remove two other duplicates
from struct driver which are the name and owner fields.

Subject: clocksource: sh_tmu: compute mult and shift before registration

Since commit 98962465ed9e6ea99c38e0af63fe1dcb5a79dc25 ("nohz: Prevent
clocksource wrapping during idle"), the CPU of an R2D board never goes
to idle. This commit assumes that mult and shift are assigned before
the clocksource is registered. As a consequence the safe maximum sleep
time is negative and the CPU never goes into idle.

This patch fixes the problem by moving mult and shift initialization
from sh_tmu_clocksource_enable() to sh_tmu_register_clocksource().

Based on the sh_tmu change in 66f49121ffa41a19c59965b31b046d8368fec3c7
("clocksource: sh_tmu: compute mult and shift before registration").
The same issues impact the sh_cmt driver, so we take the same approach
here.

Wrapping pr_fmt to the KBUILD_MODNAME prefix seems to be the trendy
thing to do these days, so just do that instead of manually tidying

Subject: bnx2: Fix hang during rmmod bnx2.

The regression is caused by:

commit 4327ba435a56ada13eedf3eb332e583c7a0586a9
    bnx2: Fix netpoll crash.

If ->open() and ->close() are called multiple times, the same napi structs
will be added to dev->napi_list multiple times, corrupting the dev->napi_list.
This causes free_netdev() to hang during rmmod.

We fix this by calling netif_napi_del() during ->close().

Also, bnx2_init_napi() must not be in the __devinit section since it is
called by ->open().

Subject: enic: bug fix: make the set/get netlink VF_PORT support symmetrical

To make get/set netlink VF_PORT truly symmetrical, we need to keep track
of what items are set and only return those items on get.  Previously, the
driver wasn't differentiating between a set of attr with a NULL string,
for example, and not setting the attr at all.  We only want to return
the NULL string if the attr was actually set with a NULL string.  Otherwise,
don't return the attr.

Subject: korina: fix deadlock on RX FIFO overrun

By calling korina_restart(), the IRQ handler tries to disable the
interrupt it's currently serving. This leads to a deadlock since
disable_irq() waits for any running IRQ handlers to finish before
returning. This patch addresses the issue by turning korina_restart()
into a workqueue task, which is then scheduled when needed.

Reproducing the deadlock is easily done using e.g. GNU netcat to send
large amounts of UDP data to the host running this driver.

Note that the same problem (and fix) applies to TX FIFO underruns, but
apparently these are less easy to trigger.

Subject: mtd/r852: Fixes in case of DMA timeout

* Don't call complete on dma completion
* do a INIT_COMPLETE before using it each time
* Report DMA read error via ecc 'correct'

I finally managed to make my system do suspend to ram propertly, and I see that
if card was inserted during suspend (while system was off), I get dma timeouts
on resume. Simple card reinsert solves the issue.
This patch solves a crash that would happen otherwise

Subject: firewire: core: check for 1394a compliant IRM, fix inaccessibility of
 Sony camcorder

Per IEEE 1394 clause 8.4.2.3, a contender for the IRM role shall check
whether the current IRM complies to 1394a-2000 or later.  If not force a
compliant node (e.g. itself) to become IRM.  This was implemented in the
older ieee1394 driver but not yet in firewire-core.

An older Sony camcorder (Sony DCR-TRV25) which implements 1394-1995 IRM
but neither 1394a-2000 IRM nor BM was now found to cause an
interoperability bug:
  - Camcorder becomes root node when plugged in, hence gets IRM role.
  - firewire-core successfully contends for BM role, proceeds to perform
    gap count optimization and resets the bus.
  - Sony camcorder ignores presence of a BM (against the spec, this is
    a firmware bug), performs its idea of gap count optimization and
    resets the bus.
  - Preceding two steps are repeated endlessly, bus never settles,
    regular I/O is practically impossible.
http://thread.gmane.org/gmane.linux.kernel.firewire.user/3913

This is an interoperability regression from the old to the new drivers.
Fix it indirectly by adding the 1394a IRM check.  The spec suggests
three and a half methods to determine 1394a compliance of a remote IRM;
we choose the method of testing the Config_ROM.Bus_Info.generation
field.  This is data that firewire-core should have readily available at
this point, i.e. does not require extra I/O.

Subject: sata_nv: don't diddle with nIEN on mcp55
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On mcp55, nIEN gets stuck once set and liteon blueray rom iHOS104-08
violates ATA specification and fails to set I on D2H Reg FIS if nIEN
is set when the command was issued.  When the other party is following
the spec, both devices can work fine but when the two flaws are put
together, they can't talk to each other.

mcp55 has its own IRQ masking mechanism and there's no reason to mess
with nIEN in the first place.  Fix it by dropping nIEN diddling from
nv_mcp55_freeze/thaw().

This was originally reported by Cengiz.  Although Cengiz hasn't
verified the fix yet, I could reproduce this problem and verfiy the
fix.  Even if Cengiz is experiencing different or additional problems,
this patch is needed.

After late HPA unlock, libata kept using the original capacity
ignoring the new larger native capacity.  Enlarging device on the fly
doesn't cause any harm.  Use the larger native capacity instead.  This
will enable on-demand HPA unlocking.

Subject: libata: implement on-demand HPA unlocking

Implement ata_scsi_unlock_native_capacity() which will be called
through SCSI layer when block layer notices that partitions on a
device extend beyond the end of the device.  It requests EH to unlock
HPA, waits for completion and returns the current device capacity.

This allows libata to unlock HPA on demand instead of having to decide
whether to unlock upfront.  Unlocking on demand is safer than
unlocking by upfront because some BIOSes write private data to the
area beyond HPA limit.  This was suggested by Ben Hutchings.

Subject: drm/radeon/kms/pm: add support for SetVoltage cmd table (V2)

- This enables voltage adjustment on r6xx+ and certain
r5xx asics.
- Voltage drop support is already available for most
r1xx-r5xx asics.

V2: endian fix for voltage table.

The default power state does not always match the default clocks and voltage
for a particular card.  The information in the firmware info table is correct
and should be used in preference to the info the default power state.

Subject: vgaarb: convert pr_devel() to pr_debug()

We want to be able to use CONFIG_DYNAMIC_DEBUG in arbiter code, switch
the few existing pr_devel() calls to pr_debug().

Also, add one more debug information regarding decoding count.

From d8bd19d2aff95e52c7f356cc2fc722584a656065 Mon Sep 17 00:00:00 2001
From: Jakob Bornecrantz <jakob@vmware.com>
Date: Tue, 1 Jun 2010 11:54:20 +0200
Subject: drm/vmwgfx: Allow userspace to change default layout. Bump minor.

The host may change the layout and, since the change is
communicated to the master, the master needs a way to
communicate the change to the kernel driver.

The minor version number is bumped to advertize the
availability of this feature.

Since the device we are resuming could be the device containing the
swap device we should ensure that the allocation cannot cause
IO.

On resume, this path is triggered when the running system tries to
continue using its devices.  If it cannot then the resume will fail;
to try to avoid this we let it dip into the emergency pools.

The majority of these changes were made when linux-2.6.18-xen.hg
changeset e8b49cfbdac0 was ported upstream in
a144ff09bc52ef3f3684ed23eadc9c7c0e57b3aa but somehow this hunk was
dropped.

Subject: i2c: Share the I2C device presence detection code

Use the same I2C device presence detection code for legacy and new
device detection functions. This is more consistent and makes the code
smaller.

Subject: i2c: Check for address validity on client registration

Do basic address validity checks when a client is being registered. We
already had checks in place for devices which are being detected, but
not for devices which are simply instantiated.

This is a very basic check. We don't want to do strict checking here
because some devices are known to infringe the I2C address constraints
(e.g. IR receivers at 7-bit address 0x7a while this value is
supposedly reserved for 10-bit addresses.) So we assume the caller
knows what it is doing.

Subject: i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

Subject: sfc: Get port number from CS_PORT_NUM, not PCI function number

A single shared memory region used to communicate with firmware is
mapped into both PCI PFs of the SFC9020 and SFL9021.  Drivers must be
able to identify which port they are addressing in order to use the
correct sub-region.  Currently we use the PCI function number, but the
PCI address may be virtualised.  Use the CS_PORT_NUM register field
defined for just this purpose.

 CONFIG_BIG_ENDIAN

Probably no one has used this driver on big-endian systems, since it was
setting up descriptor swapping if CONFIG_BIG_ENDIAN is set, which it
never is, since that symbol is not mentioned anywhere else in the kernel
source.  Switch this test to a check for __BIG_ENDIAN so it has a chance
at working.

Subject: ACPI: Fix the incorrect calculation about C-state idle time

The C-state idle time is not calculated correctly, which will return the wrong
residency time in C-state. It will have the following effects:
   1.  The system can't choose the deeper C-state when it is idle next time.
Of course the system power is increased. E.g. On one server machine about 40W
idle power is increased.
   2.  The powertop shows that it will stay in C0 running state about 95% time
although the system is idle at most time.

Subject: ACPI: Eliminate us to pm ticks conversion in common path

acpi_enter_[simple|bm] routines does us to pm tick conversion on every
idle wakeup and the value is only used in /proc/acpi display. We can
store the time in us and convert it into pm ticks before printing instead and
avoid the conversion in the common path.

Subject: ath5k: depend on CONFIG_PM_SLEEP for suspend/resume functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When building a kernel with CONFIG_PM=y but neither suspend nor
hibernate support, the compiler complains about the static functions
ath5k_pci_suspend() and ath5k_pci_resume() not being used:

drivers/net/wireless/ath/ath5k/base.c:713:12: warning: ‘ath5k_pci_suspend’ defined but not used
drivers/net/wireless/ath/ath5k/base.c:722:12: warning: ‘ath5k_pci_resume’ defined but not used

Depending on CONFIG_PM_SLEEP rather than CONFIG_PM fixes the issue.

Commit 56d1de0a21db28e41741cfa0a66e18bc8d920554, "ath5k: clean up
filter flags setting" introduced a regression in monitor mode such
that the promisc filter flag would get lost.

Although we set the promisc flag when it changed, we did not
preserve it across subsequent calls to configure_filter.  This patch
restores the original functionality.

Subject: USB: xhci: Wait for controller to be ready after reset.

After software resets an xHCI host controller, it must wait for the
"Controller Not Ready" (CNR) bit in the status register to be cleared.
Software is not supposed to ring any doorbells or write to any registers
except the status register until this bit is cleared.

Subject: USB: xhci: Print NEC firmware version.

The NEC xHCI host controller firmware version can be found by putting a
vendor-specific command on the command ring and extracting the BCD
encoded-version out of the vendor-specific event TRB.

The firmware version debug line in dmesg will look like:

xhci_hcd 0000:05:00.0: NEC firmware version 30.21

(NEC merged with Renesas Technologies and became Renesas Electronics on
April 1, 2010.  I have their OK to merge this vendor-specific code.)

The shortest period SoftDisconnect can be asserted for is 3 milliseconds

Subject: USB: ftdi_sio: fix DTR/RTS line modes

Call set_mctrl() and clear_mctrl() according to the flow control mode
selected. This makes serial communication for FT232 connected devices
work when CRTSCTS is not set.

This fixes a regression introduced by 4175f3e31 ("tty_port: If we are
opened non blocking we still need to raise the carrier"). This patch
calls the low-level driver's dtr_rts() function which consequently sets
TIOCM_DTR | TIOCM_RTS. A later call to set_termios() without CRTSCTS in
cflags, however, does not reset these bits, and so data is not actually
sent out on the serial wire.

Subject: USB: cdc-acm: fix resource reclaim in error path of acm_probe

This patch fixes resource reclaim in error path of acm_probe:

1. In the case of "out of memory (read urbs usb_alloc_urb)\n")", there
   is no need to call acm_read_buffers_free(acm) here.  Fix it by goto
   alloc_fail6 instead of alloc_fail7.
2. In the case of "out of memory (write urbs usb_alloc_urb)",
   usb_alloc_urb may fail in any iteration of the for loop.  Current
   implementation does not properly free allocated snd->urb.  Fix it by
   goto alloc_fail8 instead of alloc_fail7.
3. In the case of device_create_file(&intf->dev,&dev_attr_iCountryCodeRelDate)
   fail, acm->country_codes is kfreed. As a result, device_remove_file
   for dev_attr_wCountryCodes will not be executed in acm_disconnect.
   Fix it by calling device_remove_file for dev_attr_wCountryCodes
   before goto skip_countries.

Subject: USB: unbind all interfaces before rebinding them
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch (as1387) fixes a bug introduced during the changeover to
the runtime PM framework.  When a driver doesn't support resume or
reset-resume, and consequently its interfaces need to be unbound and
rebound, we have to unbind all the interfaces before trying to rebind
any of them.  Otherwise the driver's probe method for one interface
could try to claim a different interface and fail, because that other
interface hasn't been unbound yet.

This fixes Bugzilla #15788.  The symptom is that some USB sound cards
don't work after hibernation.

Subject: msm_serial: fix serial on trout

Set the mnd counter based on uartclk. This fixes a problem
on 7x30 where the uartclk is 19.2Mhz rather than the usual
4.8Mhz.

Trout incorrectly reports uartclk to be running at 19.2Mhz
It is actually running at 4.8Mhz.  For trout force mnd
counter values as if uartclk was fed by tcxo/4.

Anomaly 05000230 (over sampling of the UART STOP bit) applies only when
the peripheral is operating in UART mode.  So drop the anomaly handling
when the UART is in IRDA mode.

Subject: TTY/n_gsm: potential double lock

In gsm_dlci_data_kick() we call gsm_dlci_data_sweep() with the
"gsm->tx_lock" held so we can't lock it again inside
gsm_dlci_data_sweep().  I removed that lock from and added one to
gsmld_write_wakeup() instead.  The sweep function is only called from
those two places.

Subject: altera_uart: Don't take spinlock in already protected functions

Don't take the port spinlock in uart functions where the serial core
already takes care of locking/unlocking them.

The code would actually lock up on architectures where spinlocks are
implemented (not the case on nios2 where this driver is primarily used
for now, thus this bug didn't trigger).

Also protect calling altera_uart_rx_chars/altera_uart_tx_chars in the
interrupt handler by the port spinlock.

Thanks to Ian Abbott for pointing these issues out.

Subject: altera_uart: Simplify altera_uart_console_putc

The check for the TRDY flag after writing the character is not needed.
Also do a cpu_relax() inside the loop.

Pass a struct uart_port to altera_uart_console_putc, so we do not need
to get it (and dereference pointers) for every character.

Subject: tty: fix a little bug in scrup, vt.c

The code uses vc->vc_cols instead of vc->vc_size_row by mistake, it
will cause half of the region which is going to clear remain
uncleared.
The issue happens in background consoles, so it's hard to observe.

Subject: staging: Add framebuffer driver for XGI chipsets

This driver handles XG20, XG21, XG40, XG42 chipsets from XGI. They're
also known as Z7,Z9,Z11 chipsets. It's based on the SiS fb driver but
has been heavily modified by XGI to support their newer chipsets.

+	 *    hold the location of the next free queue slot, 0x85c8

+	 *    unknown to me. Anyway, this mode would require a
+	 *    translation of the MMIO commands to some kind of
+	 *    accelerator assembly and writing these commands
+	 *    to the memory location pointed to by 0x85c4.
+	 *    We will not use this, as nobody knows how this
+	 *    "assembly" works, and as it would require a complete
+	 *    re-write of the accelerator code.
+	 * 3. AGP queue mode (bit 7, 0x80). Works as 2., but keeps the
+	 *    queue in AGP memory space.
+	 *
+	 * SR26 bit 4 is called "Bypass H/W queue".
+	 * SR26 bit 1 is called "Enable Command Queue Auto Correction"
+	 * SR26 bit 0 resets the queue
+	 * Size of queue memory is encoded in bits 3:2 like this:
+	 *    00  (0x00)  512K
+	 *    01  (0x04)  1M
+	 *    10  (0x08)  2M

Subject: Staging: mid: Intel MID touch screen driver

Touchscreen driver used by intel mid devices. Some clean up by Alan Cox. This
driver is basically ready for upstreaming properly but is tied wrongly to the
SPI layer and needs firmware/SFI changes to fix that.

Subject: Staging: comedi: Give the addi_apci_* drivers different driver names

It is not currently possible for more than one of the addi_apci_*
drivers to register themselves with comedi at once because they all use
the same comedi driver name "addi_common".  Give them different names.

Subject: Staging: comedi: addi-data: don't overwrite name for request_irq()

The Addi-Data PCI drivers for Comedi use sprintf() in their comedi
"attach" routine to construct a string to pass as the name in the call
to request_irq().  All calls to "attach" routine share the same static
buffer for this name, but the contents will differ on each call
(including the comedi device number and the comedi board name).  This
changes the name displayed in /proc/interrupts for previous calls to
request_irq() using the same buffer.  Just use the board name instead;
it has slightly less information (no comedi device number) but at least
it doesn't change over the lifetime of the IRQ handler.

Subject: Staging: comedi: adv_pci_dio: Support Advantech PCI-1735U

Add support for the Advantech PCI-1735U card, including support for a
counter subdevice (based on an 82C54 counter timer chip).

The counter subdevice needs more testing, as the only person I know who
tried it couldn't get it to work!

Subject: Staging: comedi: amplc_dio200: Protect counter subdevice with
 spinlock

The internal state of an 82C54 counter timer chip will get messed up if
several threads read, write, configure, or check the status of the chip
simultaneously.  Protect the register access sequences with a spin lock.

Subject: Staging: comedi: don't write to buffer if command finished

For write(), any data copied to the data buffer after the previously
set up streaming acquisition command has finished won't be used, but a
non-empty write() does not currently return 0 (or -EPIPE on error) after
the command has finished until the data buffer has been filled up.
Change this behavior to return 0 (or -EPIPE) any time after the command
has finished, without bothering to fill up the buffer with more useless
data.

Subject: Staging: comedi: fix 8255 and DAS08 Kconfig dependancies.

Both drivers support directly or indirectly multiple bus types,
hence both are listed independent of bus types.

Subject: Staging: add MSM framebuffer driver

Qualcomm development of the MSM SOC framebuffer driver has
diverged significantly from the driver used by Android. This
is a snapshot of our current driver, in all it's agony. We are
putting this in staging to help with the process of converging
the two drivers.

At this point, the driver has been tested only in dumb
framebuffer mode.

Subject: Staging: batman-adv: fix rogue packets on shutdown

On module shutdown batman-adv would purge the internal packet
queue by sending all remaining packets which could confuse
other nodes. Now, the packets are silently discarded.

Subject: Staging: batman-adv: Call unregister_netdev on failures to get rtnl
 lock

We must call unregister_netdev when we couldn't initialise the
batman-adv module and the soft_device was registered. There are two
version of the function which we can use:
 * unregister_netdevice - removes device
 * unregister_netdev - takes rtnl semaphore and remove device

We don't hold the semaphore in an error situation. So we must use
unregister_netdev.

Free_netdev is registered as destructor in interface_setup for every
soft_device. This destructor is automatically called from
unregister_netdev and we must not call it again for the freed
net_device.

Subject: Staging: batman-adv: Don't allocate icmp packet with GFP_KERNEL

A new buffer for a packet is created when a icmp packet is received.
This happens in a context with disabled irq. Thus we are not allowed to
sleep or call function which might sleep. kmalloc must be called with
GFP_ATOMIC instead of GFP_KERNEL to ensure that it does not sleep.

Subject: Staging: wlags49_h2, wlags49_h25: fixed Kconfig dependencies

Fixes Kconfig so the wlags49_h2 and wlags49_h25 drivers can be
selected from menuconfig without having to select another WLAN
driver first. Before it could only be selected when another driver
already selected WIRELESS_EXT. Also adds WEXT_PRIV on which
the driver also depends.

Align help text in Kconfig.

Subject: fix the deadlock in qib_fs

get_sb_single() calls fill_super with superblock locked; calling
deactivate_super() will deadlock immedately.  Moreover, if fill_super
callback returns an error, get_sb_single() will release the reference
to superblock itself just fine.

Subject: vmware balloon: clamp number of collected non-balloonable pages

Limit number of accumulated non-balloonable pages during inflation cycle,
otherwise there is a chance we will be spinning and growing the list
forever.  This happens during torture tests when balloon target changes
while we are in the middle of inflation cycle and monitor starts refusing
to lock pages (since they are not needed anymore).

This reverts commit 49bbd815fd8ba26d0354900b783b767c7f47c816 ("fb_defio:
fix for non-dirty ptes").

Although the fix provided is correct, it's been suggested to avoid the
underlying race in the same way as it is currently done in filesystems
like NFS, for maintainability.

A following patch "fb_defio: redo fix for non-dirty ptes" will provide
such an alternate fix.

As pointed by Nick Piggin, ->page_mkwrite provides a way to keep a page
locked until the associated PTE is marked dirty.

Re-implement the fix by using this mechanism.

Commit f601441916d1e19291d0b4f044b4a7551e2924d0 ("imxfb: add support for
i.MX25:) has inserted the symbol HAVE_FB_IMX, which does not depend on FB
after the menuconfig FB.  This breaks the menu, presenting most of the
drivers outside of it, when using menuconfig.

Moving the symbol to the start of the file, just like HAVE_FB_ATMEL, fixes
the problem without breaking it for iMX25 configurations (tested with
ARCH=arm, no build).

Subject: omap: remove BUG_ON for disabled interrupts

Remove a BUG_ON for when interrupts are disabled during an MMC request.

During boot, interrupts can be disabled when a request is made, causing
this bug to be triggered.  In reality, there's no reason this should halt
the kernel, as the driver has proved reliable in spite of disabled
interrupts, and additionally, there's nothing in this code that would
require interrupts to be enabled.

The only setup I've managed to make it trigger on is on the HTC Herald
during bootup when the driver is built into the kernel (mostly because
that's all I have).  I believe it's related to the fact that on bootup I
get many timeout errors on "CMD5" while initializing the card.  Each CMD5
timeout triggers that bug (I changed it to a WARN_ON to get it to boot in)
due to the fact that part of the timeout code involves sending the request
again.  With interrupts turned off, that BUG would be triggered.

Subject: drm/i915: Move non-phys cursors into the GTT

Cursors need to be in the GTT domain when being accessed by the GPU.
Previously this was a fortuitous byproduct of userspace using pwrite()
to upload the image data into the cursor. The redundant clflush was
removed in commit 9b8c4a and so the image was no longer being flushed
out of the caches into main memory. One could also devise a scenario
where the cursor was rendered by the GPU, prior to being attached as the
cursor, resulting in similar corruption due to the missing MI_FLUSH.

Fixes:

  Bug 28335 - Cursor corruption caused by commit 9b8c4a0b21

Subject: iwlwifi: move sysfs_create_group to post request firmware

Move the sysfs_create_group to iwl_ucode_callback after we
have safely got the firmware.

The motivation to do this comes from a warning from lockdep which detected
that we request priv->mutex while holding s_active during a sysfs request
(show_statistics in the example copy pasted). The reverse order exists upon
request_firmware: request_firmware which is a sysfs operation
that requires s_active is run under priv->mutex.

This ensures that we don't get sysfs request before we finish to request
the firmware, avoiding this deadlock.

=======================================================

Subject: r8169: fix random mdio_write failures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some configurations need delay between the "write completed" indication
and new write to work reliably.

Realtek driver seems to use longer delay when polling the "write complete"
bit, so it waits long enough between writes with high probability (but
could probably break too). This patch adds a new udelay to make sure we
wait unconditionally some time after the write complete indication.

This caused a regression with XID 18000000 boards when the board specific
phy configuration writing many mdio registers was added in commit
2e955856ff (r8169: phy init for the 8169scd). Some of the configration
mdio writes would almost always fail, and depending on failure might leave
the PHY in non-working state.

Subject: Revert "tty: fix a little bug in scrup, vt.c"

This reverts commit 962400e8fd29981a7b166e463dd143b6ac6a3e76, which was
entirely bogus.

The code used to multiply the character offset by "vc->vc_cols", and
that's actually correct, because 'd' itself is an 'unsigned short'.  So
the pointer arithmetic already takes the size of a VGA character into
account.  Changing it to use vc_size_row (which is just "vc_cols"
shifted up to take the size of the character into account) ends up
multiplying with the VGA character size twice.

This got reported as bugs for various other subsystems, because what it
actually results in is writing the 16-bit vc_video_erase_char pattern
(usually 0x0720: 0x07 is the default attribute, 0x20 is ASCII space)
into some random other allocation.

So Markus ended up reporting this as a ext4 bug, while to Torsten Kaiser
it looked like a problem with KMS or libata.  Jeff Chua saw it in
different places.

And finally - Justin Mattock had slab poisoning enabled, and saw it as a
slab poison overwritten.  And bisected and reverted this to verify the
buggy commit.

Subject: asix: check packet size against mtu+ETH_HLEN instead of ETH_FRAME_LEN

Driver checks received packet is too large in asix_rx_fixup() and fails if it is. Problem is
that MTU might be set larger than 1500 and asix fails to work correctly with VLAN tagged
packets. The check should be 'dev->net->mtu + ETH_HLEN' instead.

Subject: pcmcia: avoid validate_cis failure on CIS override

Commit a8408c17 introduced a new check to pccard_validate_cis(),
which avoids any "late" calls to this function. This broke the
insertion of cards which require a CIS override which changes
the number of card functions. Fix this by asserting that this
is _not_ a late call, but a proper call early during the card
insertion process.

Subject: sata_sil24: fix kernel panic on ARM caused by unaligned access in
 sata_sil24

The sata_sil24 driver has six 16-bit registers that are initialised with
32-bit writes. This cause a kernel panic on ARM due to the unaligned
accesses which result.

This patch changes the accesses to the correct 16-bit ones.

Subject: ahci: redo stopping DMA engines on empty ports

Commit 96d60303fd (ahci: Turn off DMA engines when there's no device)
implemented stopping DMA engines on empty ports but it used single
sampling of status registers to determine device presence which led to
disabling of DMA engines on occupied ports.  Do it after all EH
actions are complete using device presence state determined by EH.
This avoids spurious disabling of DMA engines and simplifies the code.

Subject: drm/radeon: fix PM on non-vram cards.

PM attemps to unmap objects that aren't actually mapped into userspace ever,
so just don't bother unmapping them at this point, since all you are doing
is nothing. We should be making sure all access to these objects are locked in
kernel space instead. In theory the VRAM gart table is already done, and both
the shaders and stolen vga memory blocks are never accessed at runtime.

fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16127

Subject: drm/radeon/kms/evergreen: set accel_enabled

This is needed to enable accel in the ddx.  However,
due to a bug in older versions of the ddx, it relies
on accel being disabled in order to load properly on
evergreen chips.  To maintain compatility, we add a new
get accel param and call that from the ddx.  The old one
always returns false for evergreen cards.

[this fixes a regression with older userspaces on newer kernels].

Subject: drm/radeon/kms/pm: Misc fixes

- don't rest the power state in pm_init()
We already boot up to the default power state.  Note this
patch relies on:
drm/radeon/kms/pm: patch default power state with default clocks/voltages on r6xx+
To make sure the default power state matches the boot up state.

- In the pm resume path asic init will have set the power state
back to the default so reset the tracking state values.

Subject: drm/radeon/kms/pm: add mid profile

This adds an additional profile, mid, to the pm profile
code which takes the place of the old low profile.  The default
behavior remains the same, e.g., auto profile now selects between
mid and high profiles based on power source, however, you can now
manually force the low profile which was previously only available
as a dpms off state.  Enabling the low profile when the displays
are on has been known to cause display corruption in some cases.

Subject: drm/radeon/kms/pm: Disable voltage adjust on RS780/RS880

The vddc value in the power tables is not an actual voltage
like on discrete r6xx/r7xx/evergreen systems, but instead has
a symbolic meaning (e.g., NONE, LOW, HIGH, etc.).  See atombios.h

Most RS780/RS880 vbioses don't have a SetVoltage table anyway,
so it shouldn't be doing anything to the hardware at the moment.

I need to figure out how voltage is supposed to work on the newer
IGPs; until then, disable it.

Subject: drm/radeon/kms/r600+: use voltage from requested clock mode (v3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This fixes FDO bug #28375, it's kind of regression, so quite important to have
it for .35.

V2: Fix on RV770+ as well. All other chipsets have only one clock mode per
state.

V3: I'm out of luck today. Grepped for voltage in r*.c and missed evergreen.

Subject: drm/nouveau: completely fail init if we fail to map the PRAMIN BAR

On cards where there's a specific BAR for PRAMIN, we used to try and fall
back to the "legacy" aperture within the mmio BAR.

This is doomed to cause problems, so lets just fail completely as there's
obviously something else very wrong anyway.

Subject: drm/radeon: reset i2c valid to avoid incorrect tv-out polling.

We really don't want to be polling tv-out but since we weren't forcing the
i2c lines to invalid (tv-out has no DDC), we were adding tv connectors to the
polling setup and this was causing blinking on secondary displays.

This fixes the regression Torsten reported.

Subject: drm/radeon: don't poll tv dac if crtc2 is in use.

So when we added output polling, we'd suddenly use this code more often, and the fact that it always takes over crtc2 and messes with it during probing isn't what we really want to be happening. A more complete fix would to change it to use whatever crtc was free at the time, but for now lets stay simple and just don't poll if crtc2 is already in use.

Although a more correct fix was found I suspect we should do this as well, until we get a chance to readdres the tv out polling issues.

10, 233 is allocated officially to /dev/kmview which is shipping in
Ubuntu and Debian distributions.  vhost_net seem to have borrowed it
without making a proper request and this causes regressions in the other
distributions.

vhost_net can use a dynamic minor so use that instead.  Also update the
file with a comment to try and avoid future misunderstandings.

Subject: gianfar: Revive the driver for eTSEC devices (disable timestamping)

Since commit cc772ab7cdcaa24d1fae332d92a1602788644f7a ("gianfar: Add
hardware RX timestamping support"), the driver no longer works on
at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more
boards as well).

That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit:

  Timestamp incoming packets as padding bytes. PAL field is set
  to 8 if the PAL field is programmed to less than 8. Must be set
  to zero if TMR_CTRL[TE]=0.

I see that the commit above sets this bit, but it doesn't handle
TMR_CTRL. Manfred probably had this bit set by the firmware for
his boards. But obviously this isn't true for all boards in the
wild.

Also, I recall that Freescale BSPs were explicitly disabling the
timestamping because of a performance drop.

For now, the best way to deal with this is just disable the
timestamping, and later we can discuss proper device tree bindings
and implement enabling this feature via some property.

Realtek confirmed that a 20us delay is needed after mdio_read and
mdio_write operations. Reduce the delay in mdio_write, and add it
to mdio_read too. Also add a comment that the 20us is from hw specs.

Subject: sata_sil24: memset() overflow

cb->atapi.cdb is an array of 16 u8 elements.  The call too memset()
would set the first part of the sge array to zero as well.  It's not
a packed struct.

This one has been around for five years.  I found it with Smatch.  I
think the reason no one has seen it before is because we normally call
sil24_fill_sg() and that overwrites sge with proper information?

Subject: PCI: hotplug/cpqphp, fix NULL dereference

There are devices out there which are PCI Hot-plug controllers with
compaq PCI IDs, but are not bridges, hence have pdev->subordinate
NULL. But cpqphp expects the pointer to be non-NULL.

Add a check to the probe function to avoid oopses like:
BUG: unable to handle kernel NULL pointer dereference at 00000050
IP: [<f82e3c41>] cpqhpc_probe+0x951/0x1120 [cpqphp]
*pdpt = 0000000033779001 *pde = 0000000000000000
...

The device here was:
00:0b.0 PCI Hot-plug controller [0804]: Compaq Computer Corporation PCI Hotplug Controller [0e11:a0f7] (rev 11)
	Subsystem: Compaq Computer Corporation Device [0e11:a2f8]
