Subject: ARM: pxa: Use gpio arrays in palmld_hdd driver

Use gpio_request_array() / gpio_free_array(), this makes the code
cleaner and less error prone.

This patch also properly frees GPIOs in case ata_host_activate() call fails.

Subject: ARM: pxa: clean up set_pxa_fb_info

set_pxa_fb_info() has been a long-standing wart in the naming scheme
of the pxa_set_xxx_info() functions.  This renames the function, and
combines set_pxa_fb_parent() with set_pxa_fb_info().

Neither pxa25x_udc, nor pxa27x_udc use gpio_vbus/gpio_vbus_inverted
anymore. Drop those two fields from udc info completely.

Subject: ARM: pxafb: rework pxafb overlay memory management

PXAFB overlay memory management is something messy:
- it allocates memory dynamically on open/release, and it results
  in memory allocation failure after ~1h of uptime (system does not have
  115k of physically contiguous memory)
- in release callback it tries to free memory even if it was not
  allocated.

Also driver touches FDADR1 on main plane reconfiguration, and it can cause
problems if overlay1 is enabled.

This patch attempts to fix those issues.

Patch is based on Russell King's work.

Subject: ARM: pxafb: don't disable controller on cpufreq transition if overlay
 in use

It's not safe to disable controller if overlay(s) is enabled (results in
system hang). So we avoid to disable controller in this case. Userspace
should choose proper governor to avoid freq changing when overlay is in
use, otherwise LCD may blink.

Subject: HID: add support for Skycable 0x3f07 wireless presenter

This device contains the very same bug in report descriptor as the
Ortek ones do (i.e. LogicalMinimum == 1, which is wrong for the key
array).

As we have more reports for the Ortek devices, we are keeping the driver
name for now. Apparently there is a chip producer which sells chip with
this buggy descriptor to multiple vendors. Thus if such reports start
to come at highger frequency, we'll either have to rename the driver
accordingly, or come up with more generic workaround.

Subject: viafb: initialize margins correct

This patch initializes the margins for the initial mode correct.
This is required to get the desired initial refresh rate. Also do
more verbose sanity checking to prevent misbehavior.

Subject: ARM: mx51: Print silicon revision on boot

Having the silicon revision to appear on the boot log is a useful information.

MX31 and MX35 already show the silicon revision on boot.

Add support for displaying such information for MX51 as well.

Tested on a MX51EVK, where it shows:

CPU identified as i.MX51, silicon rev 3.0

Subject: ARM: mx5/babbage: Use gpio_request_one in babbage_fec_reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current code inside babbage_fec_reset uses gpio_direction_output with initial value of the GPIO and also sets
the GPIO value via gpio_set_value to the same level right after. This is not needed.

By using gpio_request_one it is possible to set the direction and initial value in one shot.

Subject: ARM: mx5/mx53_evk: Make the reset pin name more meaningful
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As there is a mx53_smd board in the kernel, using SMD_FEC_PHY_RST as the pin name can be misleading when used
on a MX53_EVK board.

Change the pin name to reflect the board name.

Subject: oprofile, x86: Allow setting EDGE/INV/CMASK for counter events

For some performance events it's useful to set the EDGE and INV
bits and the CMASK mask in the counter control register. The list
of predefined events Intel releases for each CPU has some events which
require these settings to get more "natural" to use higher level events.

oprofile currently doesn't allow this.

This patch adds new extra configuration fields for them, so that
they can be specified in oprofilefs.

An updated oprofile daemon can then make use of this to set them.

v2: Write back masked extra value to variable.

Subject: drm/i915/lvds: Always return connected in the absence of better
 information

The LVDS connector should default to connected. We tried our best to
verify the claims of the BIOS that the hardware exists during init(),
and then during detect() we then try to verify that the panel is open.
In the event of an unsuccessful query, we should then always report
that the LVDS panel is connected. This was only the case for gen2/3,
later generations leaked the return value from the panel probe instead.

Subject: Bluetooth: Increment unacked_frames count only the first transmit

This patch lets 'l2cap_pinfo.unacked_frames' be incremented only
the first time a frame is transmitted.

Previously it was being incremented for retransmitted packets
too resulting the value to cross the transmit window size.

That timer was introduced with commit 6bd32326cda(Bluetooth: Use
proper timer for hci command timout)

Timer seems to be running when the thing is closed. Removing the timer
unconditionally fixes the problem. And yes, it needs to be fixed
before the HCI_UP check.

Subject: nfsd: fix auth_domain reference leak on nlm operations

This was noticed by users who performed more than 2^32 lock operations
and hence made this counter overflow (eventually leading to
use-after-free's).  Setting rq_client to NULL here means that it won't
later get auth_domain_put() when it should be.

Appears to have been introduced in 2.5.42 by "[PATCH] kNFSd: Move auth
domain lookup into svcauth" which moved most of the rq_client handling
to common svcauth code, but left behind this one line.

Note that this relies on stuff currently in mfd's next tree, but this
is also a newer driver.  I'm not sure which tree it should go through,
as it's a problem that shows up in next.

From: Andres Salomon <dilinger@queued.net>

MFD changes in c738892f cause the mc13xxx_platform_data struct
to change.  This changes one more (new) user of it, fixing a build
error.

Subject: ceph: flush msgr_wq during mds_client shutdown

The release method for mds connections uses a backpointer to the
mds_client, so we need to flush the workqueue of any pending work (and
ceph_connection references) prior to freeing the mds_client.  This fixes
an oops easily triggered under UML by

 while true ; do mount ... ; umount ... ; done

Also fix an outdated comment: the flush in ceph_destroy_client only flushes
OSD connections out.  This bug is basically an artifact of the ceph ->
ceph+libceph conversion.

Subject: Blackfin: use more standard pr_fmt in the module loader

Changed pr_fmt(fmt) to make the format arguments match the format.
Changed an argument name in apply_relocate from me to mod so that
the pr_err is consistent with the other uses.
Added missing '\n' to a format.

Subject: Blackfin: defconfigs: update after misc devices defaulted to N
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The default value for misc devices was changed from Y to N which
causes problems for mini defconfigs that were relying on this
defaulting to Y.  So update all of the defconfigs accordingly.

Subject: ARM: 6833/1: perf: add required isbs() to ARMv7 backend

The ARMv7 architecture does not guarantee that effects from co-processor
writes are immediately visible to following instructions.

This patch adds two isbs to the ARMv7 perf code:

(1) Immediately after selecting an event register, so that the PMU state
    following this instruction is consistent with the new event.

(2) Immediately before writing to the PMCR, so that any previous writes
    to the PMU have taken effect before (typically) enabling the
    counters.

Subject: ARM: 6834/1: perf: reset counters on all CPUs during initialisation

ARMv7 dictates that the interrupt-enable and count-enable registers for
each PMU counter are UNKNOWN following core reset.

This patch adds a new (optional) function pointer to struct arm_pmu for
resetting the PMU state during init. The reset function is called on
each CPU via an arch_initcall in the generic ARM perf_event code and
allows the PMU backend to write sane values to any UNKNOWN registers.

Subject: ARM: 6835/1: perf: ensure overflows aren't missed due to IRQ latency

If a counter overflows during a perf stat profiling run it may overtake
the last known value of the counter:

    0        prev     new                0xffffffff
    |----------|-------|----------------------|

In this case, the number of events that have occurred is
(0xffffffff - prev) + new. Unfortunately, the event update code will
not realise an overflow has occurred and will instead report the event
delta as (new - prev) which may be considerably smaller than the real
count.

This patch adds an extra argument to armpmu_event_update which indicates
whether or not an overflow has occurred. If an overflow has occurred
then we use the maximum period of the counter to calculate the elapsed
events.

Subject: Input: wacom - report resolution for pen devices

Touch resolution is reported to the userland by retrieving the value
from the HID descriptor. But pen resolution is not since it can not
be retrieved. The current Wacom X driver has a resolution table.
To centralize the source of these values, the resolution entries are
added in the wacom_features struct for x and y coordinates respectively.
The values are then reported to the userland.

Subject: WARN_ON_SMP(): Add comment to explain ({0;})

The define to use ({0;}) for the !CONFIG_SMP case of WARN_ON_SMP()
can be confusing. As the WARN_ON_SMP() needs to be a nop when
CONFIG_SMP is not set, including all its parameters must not be
evaluated, and that it must work as both a stand alone statement
and inside an if condition, we define it to a funky ({0;}).

A simple "0" will not work as it causes gcc to give the warning that
the statement has no effect.

As this strange definition has raised a few eyebrows from some
major kernel developers, it is wise to document why we create such
a work of art.

Subject: perf symbols: Fix vsyscall symbol lookup

Perf can't currently trace into the vsyscall page.  It looks like it was
meant to work.

Tested on 2.6.38 and today's -git.

The bug is easy to reproduce.  Compile this:

int main()
{
	int i;
	struct timespec t;
	for(i = 0; i < 10000000; i++)
		clock_gettime(CLOCK_MONOTONIC, &t);
	return 0;
}

and run it through perf record; perf report.  The top entry shows
"[unknown]" and you can't zoom in.

It looks like there are two issues.  The first is a that a test for user
mode executing in kernel space is backwards.  (That's the first hunk
below).  The second (I think) is that something's wrong with the code
that generates lots of little struct dso objects for different sections
-- when it runs on vmlinux it results in bogus long_name values which
cause objdump to fail.

Subject: ARM: 6836/1: kprobes/fix emulation of LDR/STR instruction when Rn ==
 PC

The Rn value from the emulation is unconditionally written back;
this is fine as long as Rn != PC because in that case, even if the
instruction isn't a write back instruction, it will only result in the
same value being written back.

In case Rn == PC, then the emulated instruction doesn't have the
actual PC value in Rn but an adjusted value; when this is written
back, it will result in the PC being incorrectly updated.

An altenative solution would be to check bits 24 and 22 to see whether
the instruction actually is a write back instruction or not. I think
it's enough to check whether Rn != PC,  because:
- it's looks cheaper than the alternative
- to my understaning it's not permitted to update the PC with a write
back instruction, so we don't lose any ability to emulate legal
instructions.
- in case of writing back for non write back instructions where Rn != PC, it doesn't matter because the values are the same.

Regarding the second point above, it would possibly be prudent to add
some checking to prep_emulate_ldr_str(), so that instructions with
both write back and Rn == PC would be rejected.

Subject: ARM: 6826/1: Merge v6 and v7 DEBUG_LL DCC support

The inline assembly differences for v6 vs. v7 are purely
optimizations. On a v7 processor, an mrc with the pc sets the
condition codes to the 28-31 bits of the register being read. It
just so happens that the TX/RX full bits the DCC support code is
testing for are high enough in the register to be put into the
condition codes. On a v6 processor, this "feature" isn't
implemented and thus we have to do the usual read, mask, test
operations to check for TX/RX full. Thus, we can drop the v7
implementation and just use the v6 implementation for both.

When a client connects in HT mode but does not provide any valid MCS

Fix this by falling back to legacy rates if no usable MCS rates are found.

This patch moves 'key' dereference after BUG_ON(!key) so that when key is NULL
we will see proper trace instead of oops.

Subject: cfg80211: fix BSS double-unlinking (continued)

This patch adds to the fix "fix BSS double-unlinking"
(commit 3207390a8b58bfc1335750f91cf6783c48ca19ca) by Johannes Berg.

It turns out, that the double-unlinking scenario can also occur if expired
BSS elements are removed whilst an interface is performing association.

To work around that, replace list_del with list_del_init also in the
"cfg80211_bss_expire" function, so that the check for whether the BSS still is
in the list works correctly in cfg80211_unlink_bss.

Subject: mac80211: fix aggregation frame release during timeout

Suppose the aggregation reorder buffer looks like this:

x-T-R1-y-R2,

where x and y are frames that have not been received, T is a received
frame that has timed out, and R1,R2 are received frames that have not
yet timed out. The proper behavior in this scenario is to move the
window past x (skipping it), release T and R1, and leave the window at y
until y is received or R2 times out.

As written, this code will instead leave the window at R1, because it
has not yet timed out. Fix this by exiting the reorder loop only when
the frame that has not timed out AND there are skipped frames earlier in
the current valid window.

Subject: fbdev: sh_mobile_lcdcfb: fix module lock acquisition

Whenever the LCDC is to be started or stopped, a board callback is
checked for existence and invoked. Prior to the invokation, the
callback's module lock is also acquired, to be released once the
callback returns. However, the order of testing makes it possible for
the lock to be acquired and not released in case the callback does not
exist. This patch reorders the tests to prevent this particular case.

Stop including <linux/delay.h> in x86 header files which don't
need it. This will let the compiler complain when this header is
not included by source files when it should, so that
contributors can fix the problem before building on other
architectures starts to fail.

Subject: x86, microcode: Unregister syscore_ops after microcode unloaded

Currently, microcode doesn't unregister syscore_ops after it's
unloaded. So if we modprobe then rmmod microcode, the stale
microcode syscore_ops info will stay on syscore_ops_list.

Later when we're trying to reboot/halt/shutdown the machine, kernel
will panic on syscore_shutdown().

With the patch applied, I can reboot/halt/shutdown my machine successfully.

Subject: perf tools: Fixup exit path when not able to open events

We have to deal with the TUI mode in perf top, so that we don't end up
with a garbled screen when, say, a non root user on a machine with a
paranoid setting (the default) tries to use 'perf top'.

Introduce a ui__warning_paranoid() routine shared by top and record that
tells the user the valid values for /proc/sys/kernel/perf_event_paranoid.

Subject: perf tools: Emit clearer message for sys_perf_event_open ENOENT
 return

Resend of patch sent back in January 2011 in light of recent confusion around
unsupported events for a given platform.

Improve sys_perf_event_open ENOENT return handling in top and record, just
like 5a3446b does for stat.

Retry of Arnaldo's patch using ui_warning instead of die which allows the
fallback from hardware cycles to software clock.

Subject: perf symbols: Properly align symbol_conf.priv_size

If symbol_conf.priv_size is not a multiple of "sizeof(u64)" we'll bus
error on sparc64 in symbol__new because the "struct symbol *" pointer
is computed by adding symbol_conf.priv_size to the memory allocated.

We cannot isolate the fix to symbol__new and symbol__delete since the
private area is computed by subtracting the priv_size value from a
"struct symbol" pointer, so then the private area can still be
potentially unaligned.

So, simply align the symbol_conf.priv_size value in symbol__init()

Subject: libceph: fix null dereference when unregistering linger requests

We should only clear r_osd if we are neither registered as a linger or a
regular request.  We may unregister as a linger while still registered as
a regular request (e.g., in reset_osd).  Incorrectly clearing r_osd there
leads to a null pointer dereference in __send_request.

Also simplify the parallel check in __unregister_request() where we just
removed r_osd_item and know it's empty.

Subject: iwl3945: disable hw scan by default

After new NetworkManager 0.8.996 changes, hardware scanning is causing
microcode errors as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=683571
and sometimes kernel crashes:
https://bugzilla.redhat.com/show_bug.cgi?id=688252

Also with hw scan there are very bad performance on some systems
as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=671366

Since Intel no longer supports 3945, there is no chance to get proper
firmware fixes, we need workaround problems by disable hardware scanning
by default.

Subject: carl9170: Fix tx aggregation problems with some clients

Some clients seem to rely upon the reception of BlockAckReqs to flush
their rx reorder buffer. In order to fix aggregation for these clients
carl9170 should set IEEE80211_TX_STAT_AMPDU_NO_BACK to generate a
BlockAckReq if the transmission of an AMPDU subframe fails.

This fixes aggregation problems with Intel 5100 Windows STAs (and maybe
others as well).

Subject: iwlegacy: fix bugs in change_interface

If change_interface gets invoked during a firmware
restart, it may crash; prevent that from happening
by checking if ctx->vif is assigned.

Additionally, in my initial commit I forgot to set
the vif->p2p variable correctly, so fix that too.

Subject: x86, mtrr, pat: Fix one cpu getting out of sync during resume

On laptops with core i5/i7, there were reports that after resume
graphics workloads were performing poorly on a specific AP, while
the other cpu's were ok. This was observed on a 32bit kernel
specifically.

Debug showed that the PAT init was not happening on that AP
during resume and hence it contributing to the poor workload
performance on that cpu.

On this system, resume flow looked like this:

1. BP starts the resume sequence and we reinit BP's MTRR's/PAT
   early on using mtrr_bp_restore()

2. Resume sequence brings all AP's online

3. Resume sequence now kicks off the MTRR reinit on all the AP's.

4. For some reason, between point 2 and 3, we moved from BP
   to one of the AP's. My guess is that printk() during resume
   sequence is contributing to this. We don't see similar
   behavior with the 64bit kernel but there is no guarantee that
   at this point the remaining resume sequence (after AP's bringup)
   has to happen on BP.

5. set_mtrr() was assuming that we are still on BP and skipped the
   MTRR/PAT init on that cpu (because of 1 above)

6. But we were on an AP and this led to not reprogramming PAT
   on this cpu leading to bad performance.

Fix this by doing unconditional mtrr_if->set_all() in set_mtrr()
during MTRR/PAT init. This might be unnecessary if we are still
running on BP. But it is of no harm and will guarantee that after
resume, all the cpu's will be in sync with respect to the
MTRR/PAT registers.

Subject: powerpc: Restore some misc devices to our configs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Uwe Kleine-König reported:

	while working on an defconfig (arm/mx27) I noticed that just updating
	it[1] results in removing CONFIG_EEPROM_AT24=y.  The reason is that
	since commit

		v2.6.36-5965-g5f2365d (misc devices: do not enable by default)

	MISC_DEVICES isn't enabled anymore by default.  So all defconfigs that
	have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on
	MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same
	problem.

This restores those misc devices to the powerpc defconfigs.

This is used by Alsa to mmap buffers allocated with dma_alloc_coherent()
into userspace. We need a special variant to handle machines with
non-coherent DMAs as those buffers have "special" virt addresses and
require non-cachable mappings

Subject: powerpc: ARCH_PFN_OFFSET should be unsigned long

pfns are unsigned long, but MEMORY_START is phys_addr_t.  This leads
to page_to_pfn() returning phys_addr_t, and thus type mismatches in a few
print statements.

Subject: powerpc/xics: Fix numberspace mismatch from irq_desc conversion

commit 79f26c268ebad29bd75d078cfc09d3d82b30ccbd (powerpc:
platforms/pseries irq_data conversion) pushed irq_desc down into many
functions, dererencing the descriptor irq field as late as possible.

But it incorrectly passed a linix virtural irq number to RTAS,
resulting in the interrupt not being disabled and possibly
other bad things, such as another interrupt being disabled and/or
a checkstop.

In addition this missed the point of xics_mask_unknown_vec and
the seperation of xics_mask_real_irq from xics_mask_irq.  When
xics_mask_unknown_vec is called it's because the hardware delivered an
irq source for which we have no linux irq allocated, and thefore we can
not have an irq_desc allocated.

Revert xics_mask_real_irq to its prior version, naming the argument
hwirq to highlight the difference.

Subject: powerpc: Fix accounting of softirq time when idle

commit cf9efce0ce31 (powerpc: Account time using timebase rather
than PURR) used in_irq() to detect if the time was spent in
interrupt processing. This only catches hardirq context so if we
are in softirq context and in the idle loop we end up accounting it
as idle time. If we instead use in_interrupt() we catch both softirq
and hardirq time.

The issue was found when running a network intensive workload. top
showed the following:

0.0%us,  1.1%sy,  0.0%ni, 85.7%id,  0.0%wa,  9.9%hi,  3.3%si,  0.0%st

85.7% idle. But this was wildly different to the perf events data.
To confirm the suspicion I ran something to keep the core busy:

# yes > /dev/null &

8.2%us,  0.0%sy,  0.0%ni,  0.0%id,  0.0%wa, 10.3%hi, 81.4%si,  0.0%st

We only got 8.2% of the CPU for the userspace task and softirq has
shot up to 81.4%.

With the patch below top shows the correct stats:

0.0%us,  0.0%sy,  0.0%ni,  5.3%id,  0.0%wa, 13.3%hi, 81.3%si,  0.0%st

Subject: nilfs2: fix data loss in mmap page write for hole blocks

From the result of a function test of mmap, mmap write to shared pages
turned out to be broken for hole blocks.  It doesn't write out filled
blocks and the data will be lost after umount.  This is due to a bug
that the target file is not queued for log writer when filling hole
blocks.

Also, nilfs_page_mkwrite function exits normal code path even after
successfully filled hole blocks due to a change of block_page_mkwrite
function; just after nilfs was merged into the mainline,
block_page_mkwrite() started to return VM_FAULT_LOCKED instead of zero
by the patch "mm: close page_mkwrite races" (commit:
b827e496c893de0c).  The current nilfs_page_mkwrite() is not handling
this value properly.

This corrects nilfs_page_mkwrite() and will resolve the data loss
problem in mmap write.

[This should be applied to every kernel since 2.6.30 but a fix is
 needed for 2.6.37 and prior kernels]

Subject: net: Fix warnings caused by MAX_SKB_FRAGS change.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit a715dea3c8e9ef2771c534e05ee1d36f65987e64 ("net: Always
allocate at least 16 skb frags regardless of page size"), the value
of MAX_SKB_FRAGS can now take on either an "unsigned long" or an
"int" value.

This causes warnings like:

net/packet/af_packet.c: In function ‘tpacket_fill_skb’:
net/packet/af_packet.c:948: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 2 has type ‘int’

Fix by forcing the constant to be unsigned long, otherwise we have
a situation where the type of a system wide constant is variable.

Subject: ALSA: firewire-speakers: fix hang when unplugging a running device

When aborting a PCM stream, the xrun is signaled only if the stream is
running.  When disconnecting a PCM stream, calling snd_card_disconnect()
too early would change the stream into a non-running state and thus
prevent the xrun from being noticed by user space.

To prevent this, move the snd_card_disconnect() call after the xrun.

Subject: net: gre: provide multicast mappings for ipv4 and ipv6
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

My commit 6d55cb91a0020ac0 (gre: fix hard header destination
address checking) broke multicast.

The reason is that ip_gre used to get ipgre_header() calls with
zero destination if we have NOARP or multicast destination. Instead
the actual target was decided at ipgre_tunnel_xmit() time based on
per-protocol dissection.

Instead of allowing the "abuse" of ->header() calls with invalid
destination, this creates multicast mappings for ip_gre. This also
fixes "ip neigh show nud noarp" to display the proper multicast
mappings used by the gre device.

via-ircc still maintains its own array of device pointers in Linux 2.4

multiple suitable devices in the system.

Subject: via-ircc: Pass PCI device pointer to dma_{alloc, free}_coherent()

via-ircc has been passing a NULL pointer to DMA allocation functions,
which is completely invalid and results in a BUG on PowerPC.  Now
that we always have the device pointer available, pass it in.

This oops was brought in by the change "block: remove per-queue
plugging" (commit: 7eaceaccab5f40bb).  It initializes mapping->a_ops
with a NULL pointer for some pages in nilfs (e.g. btree node pages),
but mm code doesn't NULL pointer checks against mapping->a_ops. (the
check is done for each callback function)

This corrects the aops initialization and fixes the oops.

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

"len = ntohs(ip6h->payload_len)" does not include the length of the ipv6
header itself, which the rest of this function assumes, though.

This leads to a length check less restrictive as it should be in the
following line for one thing. For another, it very likely leads to an
integer underrun when substracting the offset and therefore to a very
high new value of 'len' due to its unsignedness. This will ultimately
lead to the pskb_trim_rcsum() practically never being called, even in
the cases where it should.

Subject: net/usb: Ethernet quirks for the LG-VL600 4G modem

This adds a driver for the CDC Ethernet part of this modem.  The
device's ID is blacklisted in cdc_ether.c and is white-listed in
this new driver because of the quirks needed to make it useful.
The modem's firmware exposes a CDC ACM port for modem control and a
CDC Ethernet port for network data.  The descriptors look fine but
both ports actually are some sort of multiplexers requiring non-
standard headers added/removed from every packet or they get
ignored.  All information is based on a usb traffic log from a
Windows machine.

On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with
this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.
Userspace scripts are required to talk to the CDC ACM port.

Subject: netdev: fix mtu check when TSO is enabled

In case the device where is coming from the packet has TSO enabled,
we should not check the mtu size value as this one could be bigger
than the expected value.

This is the case for the macvlan driver when the lower device has
TSO enabled. The macvlan inherit this feature and forward the packets
without fragmenting them. Then the packets go through dev_forward_skb
and are dropped. This patch fix this by checking TSO is not enabled
when we want to check the mtu size.

Subject: Atheros, atl2: Fix mem leaks in error paths of atl2_set_eeprom

We leak in some error paths of drivers/net/atlx/atl2.c:atl2_set_eeprom().
The memory allocated to 'eeprom_buff' is not freed when we return -EIO.
This patch fixes that up and also removes a pointless explicit cast.

Subject: sparc32, leon: APBUART driver must use archdata to get IRQ number

See Commit id 1636f8ac2b08410df4766449f7c86b912443cd99 (sparc/of:
Move of_device fields into struct pdev_archdata), this patch
is similar to 19e4875fb21a69fbf620e84769a74d189c69c58d (of/sparc:
fix build regression from of_device changes)

Subject: sparc32,leon: Fixed APBUART frequency detection

The UARTs may be located on different APB buses, thus have

different UART clock frequency. The system frequency is not
the same (but often) as the UART frequency, rather the APB bus
frequency that the APBUART is located at has the same
frequency, so this looks at the "freq" property instead.

Subject: powerpc: qe_ic: Rename get_irq_desc_data and get_irq_desc_chip

These two functions disappeared in commit

    0c6f8a8b917ad361319c8ace3e9f28e69bfdb4c1
    "genirq: Remove compat code"

but they still exist in qe_ic.h.
This patch renames the function to their new names.

Subject: atm/solos-pci: Use VPI.VCI notation uniformly.

Use VPI.VCI notation consistently throughout the module. This is the
one remaining place where the VCI is used before the VPI in any output.

Subject: atm/solos-pci: Don't include frame pseudo-header on transmit hex-dump

Omit pkt_hdr preamble when dumping transmitted packet as hex-dump;
we can pull this up because the frame has already been sent, and
dumping it is the last thing we do with it before freeing it.

Also include the size, vpi, and vci in the debug as is done on
receive.

Use "port" consistently instead of "device" intermittently.

Subject: atm/solos-pci: Don't flap VCs when carrier state changes

Don't flap VCs when carrier state changes; higher-level protocols
can detect loss of connectivity and act accordingly. This is more
consistent with how other network interfaces work.

We no longer use release_vccs() so we can delete it.

release_vccs() was duplicated from net/atm/common.c; make the
corresponding function exported, since other code duplicates it
and could leverage it if it were public.

Subject: connector: convert to synchronous netlink message processing

Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms)
and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct
netlink_skb_parms) removed some members from struct netlink_skb_parms
that depend on the current context, all netlink users are now required
to do synchronous message processing.

connector however queues received messages and processes them in a work
queue, which is not valid anymore. This patch converts connector to do
synchronous message processing by invoking the registered callback handler
directly from the netlink receive function.

In order to avoid invoking the callback with connector locks held, a
reference count is added to struct cn_callback_entry, the reference
is taken when finding a matching callback entry on the device's queue_list
and released after the callback handler has been invoked.

Subject: sparc64: Fix section mis-match errors.

Fix all of the problems spotted by CONFIG_DEBUG_SECTION_MISMATCH under
arch/sparc during a 64-bit defconfig build.

They fall into two categorites:

1) of_device_id is marked as __initdata, and we can never do this
   since these objects sit in the device core data structures way
   past boot.  So even if a driver will never be reloaded, we have
   to keep the device ID table around.

   Mark such cases const instead.

2) The bootmem alloc/free handling code in mdesc.c was not fully
   marked __init as it should be, thus generating a reference
   to free_bootmem_late() (which is __init) from non-__init code.

Subject: sctp: Pass __GFP_NOWARN to hash table allocation attempts.

Like DCCP and other similar pieces of code, there are mechanisms
here to try allocating smaller hash tables if the allocation
fails.  So pass in __GFP_NOWARN like the others do instead of
emitting a scary message.

Subject: gpio/pca953x: fix error handling path in probe() call

If the device fails to respond, then the error path tries to remove an
interrupt that never got registered, which causes an backtrace from the
interrupt handling code.

Fix this by ensuring that the cleanup path has two labels and use the
correct path as needed.

fixes the following error:

WARNING: at kernel/irq/manage.c:908 __free_irq+0x80/0x160()
Trying to free already-free IRQ 0

Subject: s3fb: fix Virge/GX2

Fix Virge/GX2 support in s3fb:
- fix IDs: 86C357 is GX2, 86C359 is GX2+, 86C356 probably does not exist
- add memory size detection
- drive it the same way as Trio3D/2X

The original IDs most likely came from S3 website which claims that:
- 356 is Virge/GX2 with ID=8A10, driver included in Windows 2K, XP
- 357 is Virge/GX2+ with ID=8A11, driver included in Windows ME
- 359 is Virge/GX2+ with ID=8A12, driver included in Windows ME
but:
- google search for 86C356 only reveals references to Trio3D (probably
because of a typo - Trio3D is 86C365)
- my card is clearly marked as 86C357, Virge/GX2 and has ID=8A10
- there is no driver for IDs 8A11 and 8A12 in Windows ME
- there is a driver for ID 8A10 in Windows ME that says it's GX2 (357)

Tested with #9 Reality 334 (86C357 Virge/GX2, ID=0x8A10).

Subject: serial: sh-sci: prevent setup of uninitialized serial console

Commit 906b17dc089f7fa87e37a9cfe6ee185efc90e0da introduced a condition
where the kernel will crash unless a earlyprintk parameter is specified.

Without this parameter, sci_console_init is called during early console
setup without any port being initialized, and the kernel crashes a
little bit later when uart_set_options attemps to invoke set_termios on a
port with an ops member equal to NULL.

This patch just checks in sci_console_init that the port is properly
initialized, and aborts the early console setup if it is not.

Subject: sh: sh-sci: Fix double initialization by serial_console_setup

The driver is initialized in a state with an unknown value by
serial_console_setup. And initialization fails.

This is caused by the initialization by sci_console_init.
This function does not seem to be necessary for the present sh-sci driver.

Some devices provide absolute axes with min/max of 0/0 (e.g. wacom's

these devices and require hacks in userspace to work around this.

If the kernel accepts physical devices with a min/max of 0/0, uinput
shouldn't disallow the same range.

Subject: Input: synaptics - fix crash in synaptics_module_init()

'struct dmi_system_id' arrays must always have a terminator to keep
dmi_check_system() from looking at data (and possibly crashing) it
isn't supposed to look at.

The issue went unnoticed until ef8313bb1a22e7d2125d9d758aa8a81f1de91d81,
but was introduced about a year earlier with
7705d548cbe33f18ea7713b9a07aa11047aaeca4 (which also similarly changed
lifebook.c, but the problem there got eliminated shortly afterwards).

The first hunk therefore is a stable candidate back to 2.6.33, while
the full change is needed only on 2.6.38.

Subject: Input: i8042 - downgrade selftest error message to dbg()

On a "really fragile" laptop I noticed a single
    i8042.c: i8042 controller selftest failed. (0x1 != 0x55)

error in the log. But there's no reason to print this message at
KERN_ERR level each time that loop fails, especially since the message
telling about the overall selftest failure is printed at KERN_INFO level
(on X86).

Add an actual error message for non-X86 systems, where a selftest
failure is (apparently) more serious. Remove a space in an another error
message.

Subject: drm/i915: Busy-spin wait_for condition in atomic contexts

During modesetting, we need to wait for the hardware to report
readiness by polling the registers. Normally, we call msleep() between
reads, because some state changes may take a whole vblank or more
to complete. However during a panic, we are in an atomic context and
cannot sleep. Instead, busy spin polling the termination condition.

Subject: drm/i915: Reset GMBUS controller after NAK

Once a NAK has been asserted by the slave, we need to reset the GMBUS
controller in order to continue. This is done by asserting the Software
Clear Interrupt bit and then clearing it again to restore operations.

If we don't clear the NAK, then all future GMBUS xfers will fail,
including DDC probes and EDID retrieval.

v2: Add some comments as suggested by Keith Packard.

Subject: sched: Leave sched_setscheduler() earlier if possible, do not disturb
 SCHED_FIFO tasks

sched_setscheduler() (in sched.c) is called in order of changing the
scheduling policy and/or the real-time priority of a task. Thus,
if we find out that neither of those are actually being modified, it
is possible to return earlier and save the overhead of a full
deactivate+activate cycle of the task in question.

Beside that, if we have more than one SCHED_FIFO task with the same
priority on the same rq (which means they share the same priority queue)
having one of them changing its position in the priority queue because of
a sched_setscheduler (as it happens by means of the deactivate+activate)
that does not actually change the priority violates POSIX which states,
for SCHED_FIFO:

  "If a thread whose policy or priority has been modified by
   pthread_setschedprio() is a running thread or is runnable, the effect on
   its position in the thread list depends on the direction of the
   modification, as follows: a. <...> b. If the priority is unchanged, the
   thread does not change position in the thread list. c. <...>"

     http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_08.html

 (ed: And the POSIX specification here does, briefly and somewhat unexpectedly,
      match what common sense tells us as well. )

Thus replace NR_CPUS with num_online_cpus().

Subject: perf: mmap 512 kiB by default

The default setting of perf record is to mmap 128 pages if the user
did not override with -m.

However the page size may vary accross different architecture
settings, giving different default size between each.

Moreover the kernel side still has a default max number of mlocked
pages of 512 kiB + 1 page for unprivileged users. 128 + 1 pages
with page size > 4096 overlaps this threshold.

Thus, better adapt to this limitation and set the default number of
pages to fit those 512 kiB + 1 page.

Subject: perf: Fix task context scheduling

Jiri reported:

 |
 | - once an event is created by sys_perf_event_open, task context
 |   is created and it stays even if the event is closed, until the
 |   task is finished ... thats what I see in code and I assume it's
 |   correct
 |
 | - when the task opens event, perf_sched_events jump label is
 |   incremented and following callbacks are started from scheduler
 |
 |         __perf_event_task_sched_in
 |         __perf_event_task_sched_out
 |
 |   These callback *in/out set/unset cpuctx->task_ctx value to the
 |   task context.
 |
 | - close is called on event on CPU 0:
 |         - the task is scheduled on CPU 0
 |         - __perf_event_task_sched_in is called
 |         - cpuctx->task_ctx is set
 |         - perf_sched_events jump label is decremented and == 0
 |         - __perf_event_task_sched_out is not called
 |         - cpuctx->task_ctx on CPU 0 stays set
 |
 | - exit is called on CPU 1:
 |         - the task is scheduled on CPU 1
 |         - perf_event_exit_task is called
 |         - task_ctx_sched_out unsets cpuctx->task_ctx on CPU 1
 |         - put_ctx destroys the context
 |
 | - another call of perf_rotate_context on CPU 0 will use invalid
 |   task_ctx pointer, and eventualy panic.
 |

Cure this the simplest possibly way by partially reverting the
jump_label optimization for the sched_out case.

Subject: x86, UV: Fix kdump reboot

After a crash dump on an SGI Altix UV system the crash kernel
fails to cause a reboot.  EFI mode is disabled in the kdump
kernel, so only the reboot_type of BOOT_ACPI works.

Subject: gpio/ml_ioh_gpio: Fix output value of ioh_gpio_direction_output()

The ioh_gpio_direction_output() function was missing a write to set the
desired output value.  The function would properly set the GPIO
direction, but not the output value.  The value would have to manually
be set with a follow up call to ioh_gpio_set().

Add the missing write so that ioh_gpio_direction_output() sets both the
GPIO direction and value.

Subject: quota: Don't write quota info in dquot_commit()

There's no reason to write quota info in dquot_commit(). The writing is a
relict from the old days when we didn't have dquot_acquire() and
dquot_release() and thus dquot_commit() could have created / removed quota
structures from the file. These days dquot_commit() only updates usage counters
/ limits in quota structure and thus there's no need to write quota info.

This also fixes an issue with journaling filesystem which didn't reserve
enough space in the transaction for write of quota info (it could have been
dirty at the time of dquot_commit() because of a race with other operation
changing it).

Subject: appletalk: Fix OOPS in atalk_release().

Commit 60d9f461a20ba59219fdcdc30cbf8e3a4ad3f625 ("appletalk: remove
the BKL") added a dereference of "sk" before checking for NULL in
atalk_release().

Guard the code block completely, rather than partially, with the
NULL check.

Subject: powerpc/smp: soft-replugged CPUs must go back to start_secondary

Various thing are torn down when a CPU is hot-unplugged. That CPU
is expected to go back to start_secondary when re-plugged to re
initialize everything, such as clock sources, maps, ...

Some implementations just return from cpu_die() callback
in the idle loop when the CPU is "re-plugged". This is not enough.

We fix it using a little asm trampoline which resets the stack
and calls back into start_secondary as if we were all fresh from
boot. The trampoline already existed on ppc64, but we add it for
ppc32

This is used by some "soft" hotplug implementations. I needs to
call idle_task_exit() when the CPU is going away, and we remove
the now no-longer needed set_cpu_online() and local_irq_enable()
which are handled by the return to start_secondary

Subject: powerpc/pmac/smp: Fixup smp_core99_cpu_disable() and use it on 64-bit

Use the generic code, just add the MPIC priority setting,

I don't see any use in mucking around with the decrementer,
as 32-bit will have EE off all along, and 64-bit will be able
to deal with it.

Subject: powerpc/pmac/smp: Properly NAP offlined CPU on G5

The current code soft-disables, and then goes to NAP mode which
turns interrupts on. That means that if an interrupt occurs, we
will hit the masked interrupt code path which isn't what we want,
as it will return with EE off, which will either get us out of
NAP mode, or fail to enter it (according to spec).

Instead, let's just rely on the fact that it is safe to take
decrementer interrupts on an offline CPU and leave interrupts
enabled. We can also get rid of the special case in asm for
power4_cpu_offline_powersave() and just use power4_idle().

Subject: powerpc/smp: Add a smp_ops->bringup_up() done callback

This allows us to stop abusing smp_ops->setup_cpu() for cleanup
tasks that have to take place after the initial boot time CPU
bringup.

Subject: powerpc/pmac/smp: Fix CPU hotplug crashes on some machines

On some machines that use i2c to synchronize the timebases (such
as PowerMac7,2/7,3 G5 machines), hotplug CPU would crash when
putting back a new CPU online due to the underlying i2c bus being
closed.

This uses the newly added bringup_done() callback to move the close
along with other housekeeping calls, and adds a CPU notifier to
re-open the i2c bus around subsequent hotplug operations

Subject: powerpc/smp: Don't expose per-cpu "cpu_state" array

Instead, keep it static, expose an accessor and use that from
the PowerMac code. Avoids easy namespace collisions and will
make it easier to consolidate with other implementations.

Subject: powerpc/smp: Create idle threads on demand and properly reset them

Instead of creating idle threads at boot for all possible CPUs, we
create them on demand, like x86 or ARM, and we properly call init_idle
to re-initialize an idle thread when a CPU was unplugged and is now
re-plugged.

Subject: kdump: Allow shrinking of kdump region to be overridden

On ppc64 the crashkernel region almost always overlaps an area of firmware.
This works fine except when using the sysfs interface to reduce the kdump
region. If we free the firmware area we are guaranteed to crash.

Rename free_reserved_phys_range to crash_free_reserved_phys_range and make
it a weak function so we can override it.

Subject: rcu: create new rcu_access_index() and use in mce

The MCE subsystem needs to sample an RCU-protected index outside of
any protection for that index.  If this was a pointer, we would use
rcu_access_pointer(), but there is no corresponding rcu_access_index().
This commit therefore creates an rcu_access_index() and applies it
to MCE.

Subject: ALSA: pcm: fix infinite loop in snd_pcm_update_hw_ptr0()

When period interrupts are disabled, snd_pcm_update_hw_ptr0() compares
the current time against the time estimated for the current hardware
pointer to detect xruns.  The somewhat fuzzy threshold in the while loop
makes it possible that hdelta becomes negative; the comparison being
done with unsigned types then makes the loop go through the entire 263
negative range, and, depending on the value, never reach an unsigned
value that is small enough to stop the loop.  Doing this with interrupts
disabled results in the machine locking up.

To prevent this, ensure that the loop condition uses signed types for
both operands so that the comparison is correctly done.

Many thanks to Kelly Anderson for debugging this.

Subject: [IA64] fix build warning: argument 1 of 'irqd_irq_disabled'

In commit f5e5bf088bd3d30990efb7429aaf9f1e5134ffd6
  ia64: Use irqd_irq_disabled() instead of desc->status access

Thomas forgot to convert from irq to *irq_data.

Add a call to irq_get_irq_data() to fix that.

Subject: usbnet: use eth%d name for known ethernet devices

The documentation for the USB ethernet devices suggests that
only some devices are supposed to use usb0 as the network interface
name instead of eth0. The logic used there, and documented in
Kconfig for CDC is that eth0 will be used when the mac address
is a globally assigned one, but usb0 is used for the locally
managed range that is typically used on point-to-point links.

Unfortunately, this has caused a lot of pain on the smsc95xx
device that is used on the popular pandaboard without an
EEPROM to store the MAC address, which causes the driver to
call random_ether_address().

Obviously, there should be a proper MAC addressed assigned to
the device, and discussions are ongoing about how to solve
this, but this patch at least makes sure that the default
interface naming gets a little saner and matches what the
user can expect based on the documentation, including for
new devices.

The approach taken here is to flag whether a device might be a
point-to-point link with the new FLAG_POINTTOPOINT setting in
the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT
and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one
of the two.  The usbnet framework only looks at the MAC address
for device naming if both flags are set, otherwise it trusts the
flag.

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

dev_ethtool_get_rx_csum() won't report rx checksumming when it's not
changeable and driver is converted to hw_features and friends. Fix this.

(dev->hw_features & NETIF_F_RXCSUM) check is dropped - if the
ethtool_ops->get_rx_csum is set, then driver is not coverted, yet.

Subject: tcp: len check is unnecessarily devastating, change to WARN_ON
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All callers are prepared for alloc failures anyway, so this error
can safely be boomeranged to the callers domain without super
bad consequences. ...At worst the connection might go into a state
where each RTO tries to (unsuccessfully) re-fragment with such
a mis-sized value and eventually dies.

Subject: drm/radeon/kms: pageflipping cleanup for avivo+

Avoid touching the flip setup regs while
acceleration is running.  Set them at modeset
rather than during pageflip.  Touching these
regs while acceleration is active caused hangs
on pre-avivo chips.  These chips do not seem
to be affected, but better safe than sorry,
plus it avoids repeatedly reprogramming the
regs every flip.

Subject: [S390] Fix parameter passing for smp_switch_to_cpu()

After the execution has been switched to the destination CPU, the target
function is called with the wrong parameter. According to the C calling
convention on s390, the first parameter should be loaded into register 2.
Currently in smp_restart_cpu() it is stored in register 3. To fix this, we
load the parameter into the correct register 2.

Subject: [S390] qdio: fix init sequence

Reorder the initialization sequence of the qdio module to avoid
writing to an uninitialized debug feature entry. Also reorder
the exit function to restore a consistent cleanup path.

Subject: [S390] cio: prevent purging of CCW devices in the online state

The cio_ignore purge function is intended to only remove CCW devices
which are in the offline state. There is a time frame after the purge
function finished where a CCW device is scheduled for removal but
still accessible. When the device is set online during this time
frame, it may first appear online before it is then removed.

Fix this by preventing that CCW devices can be set online while there
is work (such as removal triggered by the purge function) for it
pending. Also ensure that the purge function does not schedule devices
for removal which are in the process of being set online.

Subject: [S390] compile fix for latest binutils

The latest binutils won't accept the stfl instruction with march=g5
which is the correct behaviour. Unfortunately head.S is assembled
with -march=g5 even if the target cpu is z900 or later. To get
31-bit kernels compiled again the easiest fix is to use the .insn
notation for the stfl instruction in head.S.

Subject: netfilter: ipset: references are protected by rwlock instead of mutex

The timeout variant of the list:set type must reference the member sets.
However, its garbage collector runs at timer interrupt so the mutex
protection of the references is a no go. Therefore the reference protection
is converted to rwlock.

Subject: netfilter: h323: bug in parsing of ASN1 SEQOF field

Static analyzer of clang found a dead store which appears to be a bug in
reading count of items in SEQOF field, only the lower byte of word is
stored. This may lead to corrupted read and communication shutdown.

The bug has been in the module since it's first inclusion into linux
kernel.

[Patrick: the bug is real, but without practical consequence since the
 largest amount of sequence-of members we parse is 30.]

Subject: IPVS: fix NULL ptr dereference in ip_vs_ctl.c
 ip_vs_genl_dump_daemons()

ipvsadm -ln --daemon will trigger a Null pointer exception because
ip_vs_genl_dump_daemons() uses skb_net() instead of skb_sknet().

To prevent others from NULL ptr a check is made in ip_vs.h skb_net().

Subject: edac/mpc85xx: Limit setting/clearing of HID1[RFXE] to e500v1/v2 cores

Only the e500v1/v2 cores have HID1[RXFE] so we should attempt to set or
clear this register bit on them.  Otherwise we get crashes like:

Subject: x86-32, NUMA: Fix ACPI NUMA init broken by recent x86-64 change

Commit d8fc3afc49 (x86, NUMA: Move *_numa_init() invocations
into initmem_init()) moved acpi_numa_init() call into NUMA
initmem_init() but forgot to update 32bit NUMA init breaking ACPI
NUMA configuration for 32bit.

acpi_numa_init() call was later moved again to srat_64.c.  Match
it by adding the call to get_memcfg_from_srat() in srat_32.c.

Subject: netfilter: af_info: add 'strict' parameter to limit lookup to .oif

ipv6 fib lookup can set RT6_LOOKUP_F_IFACE flag to restrict search
to an interface, but this flag cannot be set via struct flowi.

Also, it cannot be set via ip6_route_output: this function uses the
passed sock struct to determine if this flag is required
(by testing for nonzero sk_bound_dev_if).

Work around this by passing in an artificial struct sk in case
'strict' argument is true.

This is required to replace the rt6_lookup call in xt_addrtype.c with
nf_afinfo->route().

Subject: netfilter: xt_conntrack: fix inverted conntrack direction test

--ctdir ORIGINAL matches REPLY packets, and vv:

userspace sets "invert_flags &= ~XT_CONNTRACK_DIRECTION" in ORIGINAL
case.

Thus: (CTINFO2DIR(ctinfo) == IP_CT_DIR_ORIGINAL) ^
      !!(info->invert_flags & XT_CONNTRACK_DIRECTION))

yields "1 ^ 0", which is true -> returns false.

Reproducer:
iptables -I OUTPUT 1 -p tcp --syn -m conntrack --ctdir ORIGINAL

Subject: ntp: fix non privileged system time shifting

The ADJ_SETOFFSET bit added in commit 094aa188 ("ntp: Add ADJ_SETOFFSET
mode bit") also introduced a way for any user to change the system time.
Sneaky or buggy calls to adjtimex() could set

    ADJ_OFFSET_SS_READ | ADJ_SETOFFSET

which would result in a successful call to timekeeping_inject_offset().
This patch fixes the issue by adding the capability check.

Subject: mac80211: fix comment regarding aggregation buf_size

The description for buf_size was misleading and
just said you couldn't TX larger aggregates, but
of course you can't TX aggregates in a way that
would exceed the window either, which is possible
even if the aggregates are shorter than that.

Expand the description, thanks to Emmanuel for
explaining this to me.

Cleaning the ieee80211_rx_data.flags field here is wrong, instead the
flags should be valid accross processing the frame on different
interfaces. Fix this by removing the incorrect flags=0 assignment.

Subject: zd1211rw: remove URB_SHORT_NOT_OK flag in zd_usb_iowrite16v_async()

Patch removes the bogus flag introduced by upstream commit
eefdbec1ea8b7093d2c09d1825f68438701723cf. Old code had buffer length check
that new code tried to handle with URB_SHORT_NOT_OK flag. With USB debugging
enabled bogus flag caused usb_submit_urb fail.

Remove URB_SHORT_NOT_OK flag and add buffer length check to urb completion
handler.

Subject: wl12xx: fix potential buffer overflow in testmode nvs push

We were allocating the size of the NVS file struct and not checking
whether the length of the buffer passed was correct before copying it
into the allocated memory.  This is a security hole because buffer
overflows can occur if the userspace passes a bigger file than what is
expected.

With this patch, we check if the size of the data passed from
userspace matches the size required.

This bug was introduced in 2.6.36.

Subject: ext4: remove unnecessary [cm]time update of quota file

It is not necessary to update [cm]time of quota file on each quota
file write and it wastes journal space and IO throughput with inode
writes. So just remove the updating from ext4_quota_write() and only
update times when quotas are being turned off. Userspace cannot get
anything reliable from quota files while they are used by the kernel
anyway.

Subject: ext4: fix credits computing for indirect mapped files

When writing a contiguous set of blocks, two indirect blocks could be
needed depending on how the blocks are aligned, so we need to increase
the number of credits needed by one.

[ Also fixed a another bug which could further underestimate the
  number of journal credits needed by 1; the code was using integer
  division instead of DIV_ROUND_UP() -- tytso]

Subject: ext4: fix a double free in ext4_register_li_request

In ext4_register_li_request, we malloc a ext4_li_request and
inserts it into ext4_li_info->li_request_list. In case of any
error later, we free it in the end.  But if we have some error
in ext4_run_lazyinit_thread, the whole li_request_list will be
dropped and freed in it. So we will double free this ext4_li_request.

This patch just sets elr to NULL after it is inserted to the list
so that the latter kfree won't double free it.

Subject: tty: fix endless work loop when the buffer fills up

Commit f23eb2b2b285 ('tty: stop using "delayed_work" in the tty layer')
ended up causing hung machines on UP with no preemption, because the
work routine to flip the buffer data to the ldisc would endlessly re-arm
itself if the destination buffer had filled up.

With the delayed work, that only caused a timer-driving polling of the
tty state every timer tick, but without the delay we just ended up with
basically a busy loop instead.

Stop the insane polling, and instead make the code that opens up the
receive room re-schedule the buffer flip work.  That's what we should
have been doing anyway.

This same "poll for tty room" issue is almost certainly also the cause
of excessive kworker activity when idle reported by Dave Jones, who also
reported "flush_to_ldisc executing 2500 times a second" back in Nov 2010:

  http://lkml.org/lkml/2010/11/30/592

which is that silly flushing done every timer tick.  Wasting both power
and CPU for no good reason.

General coding style and comment fixes; no code changes:

 - Use multi-line-comment coding style.
 - Put some function signatures completely on one line.
 - Hyphenate some words.
 - Spell Posix as POSIX.
 - Correct typos & spellos in some comments.
 - Drop trailing whitespace.
 - End sentences with periods.

Subject: kemleak-test: build as module only

mm/kmemleak-test.c is used to provide an example of how kmemleak
tool works.

Memory is leaked at module unload-time, so building the test
in kernel (Y) makes the leaks impossible and the test useless.

Qualify DEBUG_KMEMLEAK_TEST config symbol with "depends on m",
to restrict module-only building.

-LED handling under Linux
-========================
-
-If you're reading this and thinking about keyboard leds, these are
-handled by the input subsystem and the led class is *not* needed.
-
-In its simplest form, the LED class just allows control of LEDs from
-userspace. LEDs appear in /sys/class/leds/. The maximum brightness of the
-LED is defined in max_brightness file. The brightness file will set the brightness
-of the LED (taking a value 0-max_brightness). Most LEDs don't have hardware
-brightness support so will just be turned on for non-zero brightness settings.
-
-The class also introduces the optional concept of an LED trigger. A trigger
-is a kernel based source of led events. Triggers can either be simple or
-complex. A simple trigger isn't configurable and is designed to slot into
-existing subsystems with minimal additional code. Examples are the ide-disk,
-nand-disk and sharpsl-charge triggers. With led triggers disabled, the code
-optimises away.
-
-Complex triggers whilst available to all LEDs have LED specific
-parameters and work on a per LED basis. The timer trigger is an example.
-The timer trigger will periodically change the LED brightness between
-LED_OFF and the current brightness setting. The "on" and "off" time can
-be specified via /sys/class/leds/<device>/delay_{on,off} in milliseconds.
-You can change the brightness value of a LED independently of the timer
-trigger. However, if you set the brightness value to LED_OFF it will
-also disable the timer trigger.
-
-You can change triggers in a similar manner to the way an IO scheduler
-is chosen (via /sys/class/leds/<device>/trigger). Trigger specific
-parameters can appear in /sys/class/leds/<device> once a given trigger is
-selected.
-
-
-Design Philosophy
-=================
-
-The underlying design philosophy is simplicity. LEDs are simple devices
-and the aim is to keep a small amount of code giving as much functionality
-as possible.  Please keep this in mind when suggesting enhancements.
-
-
-LED Device Naming
-=================
-
-Is currently of the form:
-
-"devicename:colour:function"
-
-There have been calls for LED properties such as colour to be exported as
-individual led class attributes. As a solution which doesn't incur as much
-overhead, I suggest these become part of the device name. The naming scheme
-above leaves scope for further attributes should they be needed. If sections
-of the name don't apply, just leave that section blank.
-
-
-Hardware accelerated blink of LEDs
-==================================
-
-Some LEDs can be programmed to blink without any CPU interaction. To
-support this feature, a LED driver can optionally implement the
-blink_set() function (see <linux/leds.h>). To set an LED to blinking,
-however, it is better to use use the API function led_blink_set(),
-as it will check and implement software fallback if necessary.
-
-To turn off blinking again, use the API function led_brightness_set()
-as that will not just set the LED brightness but also stop any software
-timers that may have been required for blinking.
-
-The blink_set() function should choose a user friendly blinking value
-if it is called with *delay_on==0 && *delay_off==0 parameters. In this
-case the driver should give back the chosen value through delay_on and
-delay_off parameters to the leds subsystem.
-
-Setting the brightness to zero with brightness_set() callback function
-should completely turn off the LED and cancel the previously programmed
-hardware blinking function, if any.
-
-
-Known Issues
-============
-
-The LED Trigger core cannot be a module as the simple trigger functions
-would cause nightmare dependency issues. I see this as a minor issue
-compared to the benefits the simple trigger functionality brings. The
-rest of the LED subsystem can be modular.
-
-
-Future Development
-==================
-
-At the moment, a trigger can't be created specifically for a single LED.
-There are a number of cases where a trigger might only be mappable to a
-particular LED (ACPI?). The addition of triggers provided by the LED driver
-should cover this option and be possible to add without breaking the
-current interface.

-Description
------------
-The LP3944 is a helper chip that can drive up to 8 leds, with two programmable
-DIM modes; it could even be used as a gpio expander but this driver assumes it
-is used as a led controller.
-
-The DIM modes are used to set _blink_ patterns for leds, the pattern is
-specified supplying two parameters:
-  - period: from 0s to 1.6s
-  - duty cycle: percentage of the period the led is on, from 0 to 100
-
-Setting a led in DIM0 or DIM1 mode makes it blink according to the pattern.
-See the datasheet for details.
-
-LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
-leds, the camera flash light and the lcds power.
-
-
-Notes
------
-The chip is used mainly in embedded contexts, so this driver expects it is
-registered using the i2c_board_info mechanism.
-
-To register the chip at address 0x60 on adapter 0, set the platform data
-according to include/linux/leds-lp3944.h, set the i2c board info:
-
-	static struct i2c_board_info __initdata a910_i2c_board_info[] = {
-		{
-			I2C_BOARD_INFO("lp3944", 0x60),
-			.platform_data = &a910_lp3944_leds,
-		},
-	};
-
-and register it in the platform init function
-
-	i2c_register_board_info(0, a910_i2c_board_info,
-			ARRAY_SIZE(a910_i2c_board_info));

Subject: staging: hv: update dist release parsing in hv_kvp_daemon

The current code to parse the distribution file handles only files with
at least 3 lines. openSuSE has 2 lines and Redhat only one (according to
google).
Update the parser to handle up to three lines properly. Also make the
buffer allocation dynamic and remove a few casts to avoid compiler
warnings.

Subject: staging: rts_pstor: set lun_mode in a different place

In sony notebook, card reader will be configured as two-lun mode
through EFUSE. In this situation, MS card can't be recognized
properly because driver does only support single-lun mode in default.
In this patch, lun_mode is set in a different place, so driver can
detect the EFUSE configuation automatically.

-RAR Handler (memrar) Driver TODO Items
-======================================
-
-Maintainer: Eugene Epshteyn <eugene.epshteyn@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

-What:		/dev/memrar
-Date:		March 2010
-KernelVersion:	2.6.34
-Contact:	Eugene Epshteyn <eugene.epshteyn@intel.com>
-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.

- *      This simple allocator implementation provides a
- *      malloc()/free()-like interface for reserving space within a
- *      previously reserved block of memory.  It is not specific to
- *      any hardware, nor is it coupled with the lower level paging
- *      mechanism.
- *
- *      The primary goal of this implementation is to provide a means
- *      to partition an arbitrary block of memory without actually
- *      accessing the memory or incurring any hardware side-effects
- *      (e.g. paging).  It is, in effect, a bookkeeping mechanism for
- *      buffers.

  [after]
    $ mount | grep sdc2
    /dev/sdc2 on /test12 type btrfs (rw,space_cache,compress=lzo)
    $ cat /proc/mounts | grep sdc2

Subject: Btrfs: Fix oops for defrag with compression turned on

When we defrag a file, whose size can be fit into an inline extent,
with compression enabled, the compress type is set to be
fs_info->compress_type, which is 0 if the btrfs filesystem is mounted
without compress option. This leads to oops.

checking the object id of the inode's key, and we have to clear __GFP_FS flag

Subject: Btrfs: Fix uninitialized root flags for subvolumes

root_item->flags and root_item->byte_limit are not initialized when
a subvolume is created. This bug is not revealed until we added
readonly snapshot support - now you mount a btrfs filesystem and you
may find the subvolumes in it are readonly.

To work around this problem, we steal a bit from root_item->inode_item->flags,
and use it to indicate if those fields have been properly initialized.
When we read a tree root from disk, we check if the bit is set, and if
not we'll set the flag and initialize the two fields of the root item.

Subject: Btrfs: fix free space cache when there are pinned extents and
 clusters V2

I noticed a huge problem with the free space cache that was presenting
as an early ENOSPC.  Turns out when writing the free space cache out I
forgot to take into account pinned extents and more importantly
clusters.  This would result in us leaking free space everytime we
unmounted the filesystem and remounted it.

I fix this by making sure to check and see if the current block group
has a cluster and writing out any entries that are in the cluster to the
cache, as well as writing any pinned extents we currently have to the
cache since those will be available for us to use the next time the fs
mounts.

This patch also adds a check to the end of load_free_space_cache to make
sure we got the right amount of free space cache, and if not make sure
to clear the cache and re-cache the old fashioned way.

Subject: Btrfs: don't warn in btrfs_add_orphan

When I moved the orphan adding to btrfs_truncate I missed the fact that during
orphan cleanup we just add the orphan items to the orphan list without going
through btrfs_orphan_add, which results in lots of warnings on mount if you have
any orphan items that need to be truncated.  Just remove this warning since it's
ok, this will allow all of the normal space accounting take place.  Thanks,

Subject: staging: brcm80211: fix for 'AC_BE txop..' logs spammed problem

Larry Finger reported this issue. The driver, under certain
conditions, spews log messages like this:

wl0: wlc_d11hdrs_mac80211: AC_BE txop exceeded phylen 159/256
 dur 1778/1504

These log messages turned out to be false alarms. Root cause was
that the AC was derived from the sk_buff::priority field. Fix was
to derive the AC from the sk_buff using skb_get_queue_mapping()

Subject: staging: brcm80211: fix for 'Short CCK' log spam

Larry Finger reported this issue. Under certain conditions the log
file would be spammed with 'Short CCK' messages. Since this does
not indicate an error condition, the log message was simply
deleted. Also, the RX_FLAG_SHORTPRE flag in rx_status->flag, on
CCK reception, is now only set on short preamble reception (it used
to be set both CCK short and long preambles).

These 3 drivers contain much duplicated (triplicated) code, so
building them as built-in results in many errors like:

(.text+0x1b160): multiple definition of `ieee80211_sta_ps_sleep'

Prevent this configuration by making them all buildable only as
loadable modules (similar to the vt665[56] patch last week).

Subject: powerpc/kexec: Fix mismatched ifdefs for PPC64/SMP.

Commit b3df895aebe091b1657 "powerpc/kexec: Add support for FSL-BookE"
introduced the original PPC_STD_MMU_64 checks around the function
crash_kexec_wait_realmode().   Then commit c2be05481f61252
"powerpc: Fix default_machine_crash_shutdown #ifdef botch" changed
the ifdef around the calling site to add a check on SMP, but the
ifdef around the function itself was left unchanged, leaving an
unused function for PPC_STD_MMU_64=y and SMP=n

Rather than have two ifdefs that can get out of sync like this,
simply put the corrected conditional around the function and use
a stub to get rid of one set of ifdefs completely.

Subject: UBIFS: do not read flash unnecessarily

This fix makes the 'dbg_check_old_index()' function return
immediately if debugging is disabled, instead of executing
incorrect 'goto out' which causes UBIFS to:

1. Allocate memory
2. Read the flash

On every commit. OK, we do not commit that often, but it is
still silly to do unneeded I/O anyway.

Credits to coverity for spotting this silly issue.

They happen when we re-mount from R/O mode to R/W mode. While
re-mounting, we write to the media, but we still have the c->ro_mount
flag set. The fix is very simple - just clear the flag before
starting re-mounting R/W.

These warnings are caused by the following commit:

Subject: UBIFS: do not select KALLSYMS_ALL

All UBIFS needs is to make sure we stacktraces when UBIFS debugging
is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL
is not necessary. Moreover, Randy Dunlap reported that UBIFS causes
the following Kconfig dependency warning:

warning: (UBIFS_FS_DEBUG && LOCKDEP && LATENCYTOP) selects KALLSYMS_ALL
which has unmet direct dependencies (DEBUG_KERNEL && KALLSYMS)

The reason is that KALLSYMS_ALL requires DEBUG_KERNEL and KALLSYMS, so
ideally, to select KALLSYMS_ALL we'd need to select DEBUG_KERNEL and
KALLSYMS first.

This seems to be too much to select. The easiest way to go is to forget
about KALLSYMS_ALL and just select KALLSYMS when UBIFS debugging is
enabled - that should be enough for stackdumps.

This is just a small clean-up patch which simlifies and unifies the
error path in the dbg_debugfs_init_fs(). We have common error path
for all failure cases in this function except of the very first
case. And this patch makes the first failure case use the same
error path as the other cases by using the 'fname' and 'dent'
variables.

Subject: UBIFS: fix error path in dbg_debugfs_init_fs

The debug interface is substandard and on error returns either
NULL or an error code packed in the pointer. So using "IS_ERR"
for the pointers returned by debugfs function is incorrect.
Instead, we should use IS_ERR_OR_NULL.

This path is an improved vestion of the original patch from
Phil Carmody.

Subject: UBIFS: fix debugging failure in dbg_check_space_info

This patch fixes a debugging failure with which looks like this:
UBIFS error (pid 32313): dbg_check_space_info: free space changed from 6019344 to 6022654

The reason for this failure is described in the comment this patch adds
to the code. But in short - 'c->freeable_cnt' may be different before
and after re-mounting, and this is normal. So the debugging code should
make sure that free space calculations do not depend on 'c->freeable_cnt'.

A similar issue has been reported here:
http://lists.infradead.org/pipermail/linux-mtd/2011-April/034647.html

This patch should fix it.

For the -stable guys: this patch is only relevant for kernels 2.6.30
onwards.

Subject: UBI: check if we are in RO mode in the erase routine

'do_sync_erase()' has to check whether we are in R/O mode before
erasing the PEB. This patch adds the check and while on it, adds an
assertion which validates the 'pnum' argument, as well as removes
a check which is always true because it has already been done
few lines before.

Coverity spotted that UBI debugging code tries to compare
an array and NULL, which obviously makes little sense. Kill
this check.

Subject: UBI: do not select KALLSYMS_ALL

All UBI needs is to make sure we stacktraces when UBI debugging
is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL
is not necessary.

And the current Kconfig line we have:

select KALLSYMS_ALL if KALLSYMS && DEBUG_KERNEL

is just too complex to be sane and right. But this "if" part there
is needed to prevent "unmet direct dependency" warnings, because
KALLSYMS_ALL depends on KALLSYMS and DEBUG_KERNEL, so we cannot
just select KALLSYMS_ALL.

Anyway, this feels messy, and we do not seem to really need KALLSYMS_ALL,
so select KALLSYMS instead.

Subject: sched: Clean up rebalance_domains() load-balance interval calculation

Instead of the possible multiple-evaluation of num_online_cpus()
in rebalance_domains() that Linus reported, avoid it altogether
in the normal case since it's implemented with a Hamming weight
function over a cpu bitmask which can be darn expensive for those
with big iron.

This also makes it cleaner, smaller and documents the code.

Subject: drm/i915/crt: Remove 0xa0 probe for VGA

This is a moral revert of 6ec3d0c0e9c0c605696e91048eebaca7b0c36695.

Following the fix to reset the GMBUS controller after a NAK, we finally
utilize the 0xa0 probe for a CRT connection. And discover that the code
is broken. Shock.

There are a number of issues, but following a key insight from Dave
Airlie, that 0xA0 is an invalid address on a 7-bit bus (though not if we
were to enable 10-bit addressing), and would look like the EDID port
0x50, it is possible to see where the confusion starts.

In short, a write to 0xA0 is accepted by the GMBUS controller which we
interpreted as meaning the existence of a connection (a slave on the
other end of the wire ACKing the write). That was false.

During testing with a broken GMBUS implementation, which never reset an
earlier NAK, this test always reported a NAK and so we proceeded on to
the next test.

Subject: drm/i915/lvds: Remove 0xa0 DDC probe for LVDS

This is a revert of 428d2e828c0a68206e5158a42451487601dc9194.

This is broken in the same manner as for VGA: trying to write to an
invalid address on the (currently 7-bit) i2c bus.

One notable failure appears to be for MacBooks. The scary part was that
it gave the appearance of working (i.e. reporting the absence of the
panel) on various all-in-one machines with ghost LVDS panels and not
failing for laptops.

Subject: perf probe: Fix listing incorrect line number with inline function

Fix a bug showing incorrect line number when a probe is put on the head of an
inline function. This patch updates find_perf_probe_point() and introduces new
rules to get correct line number.

 - If debuginfo doesn't have a correct file name, we shouldn't return line
   number too, because, without file name, line number is meaningless.

 - If the address is in a function, it stores the function name and the offset
   from the function entry.

   - If the address is on a line, it tries to get the relative line number from
     the function entry line, except for the address is same as the entry
     address of the function (in this case, the relative line number should
     be 0).

     - If the address is in an inline function entry (call-site), it uses the
       inline function call line number as the line on which the address is.

   - If the address is in an inline function body, it stores the inline
     function name and offset from the inline function call site instead of the
     (non-inlined) function.

Subject: block: get rid of elv_insert() interface

Merge it with __elv_add_request(), it's pretty pointless to
have a function with only two callers. The main interface
is elv_add_request()/__elv_add_request().

add their own static address_space_operations without any

fs/inode.c already has an empty_aops that it uses for init
purposes. Lets export that and use it in the places where
an otherwise empty aops was defined.

Subject: dm: improve block integrity support

The current block integrity (DIF/DIX) support in DM is verifying that
all devices' integrity profiles match during DM device resume (which
is past the point of no return).  To some degree that is unavoidable
(stacked DM devices force this late checking).  But for most DM
devices (which aren't stacking on other DM devices) the ideal time to
verify all integrity profiles match is during table load.

Introduce the notion of an "initialized" integrity profile: a profile
that was blk_integrity_register()'d with a non-NULL 'blk_integrity'
template.  Add blk_integrity_is_initialized() to allow checking if a
profile was initialized.

Update DM integrity support to:
- check all devices with _initialized_ integrity profiles match
  during table load; uninitialized profiles (e.g. for underlying DM
  device(s) of a stacked DM device) are ignored.
- disallow a table load that would result in an integrity profile that
  conflicts with a DM device's existing (in-use) integrity profile
- avoid clearing an existing integrity profile
- validate all integrity profiles match during resume; but if they
  don't all we can do is report the mismatch (during resume we're past
  the point of no return)

Subject: block: fix request sorting at unplug

Comparison function for list_sort() must be anticommutative,
otherwise it is not sorting in ordinary meaning.

But fortunately list_sort() always check ((*cmp)(priv, a, b) <= 0)
it not distinguish negative and zero, so comparison function can
implement only less-or-equal instead of full three-way comparison.

Subject: ide: always ensure that blk_delay_queue() is called if we have
 pending IO

Just because we are not requeuing a request does not mean that
some aren't pending. So always issue a blk_delay_queue() if
either we are requeueing OR there's pending IO.

This fixes a boot problem for some IDE boxes.

Subject: inotify: fix double free/corruption of stuct user

On an error path in inotify_init1 a normal user can trigger a double
free of struct user.  This is a regression introduced by a2ae4cc9a16e
("inotify: stop kernel memory leak on file creation failure").

We fix this by making sure that if a group exists the user reference is
dropped when the group is cleaned up.  We should not explictly drop the
reference on error and also drop the reference when the group is cleaned
up.

The new lifetime rules are that an inotify group lives from
inotify_new_group to the last fsnotify_put_group.  Since the struct user
and inotify_devs are directly tied to this lifetime they are only
changed/updated in those two locations.  We get rid of all special
casing of struct user or user->inotify_devs.

Subject: jbd2: fix potential memory leak on transaction commit

There is potential memory leak of journal head in function
jbd2_journal_commit_transaction. The problem is that JBD2 will not
reclaim the journal head of commit record if error occurs or journal
is abotred.

I use the following script to reproduce this issue, on a RHEL6
system. I found it very easy to reproduce with async commit enabled.

mount /dev/sdb /mnt -o journal_checksum,journal_async_commit
touch /mnt/xxx
echo offline > /sys/block/sdb/device/state
sync
umount /mnt
rmmod ext4
rmmod jbd2

Removal of the jbd2 module will make slab complaining that
"cache `jbd2_journal_head': can't free all objects".

Subject: ext4: init timer earlier to avoid a kernel panic in __save_error_info

During mount, when we fail to open journal inode or root inode, the
__save_error_info will mod_timer. But actually s_err_report isn't
initialized yet and the kernel oops. The detailed information can
be found https://bugzilla.kernel.org/show_bug.cgi?id=32082.

The best way is to check whether the timer s_err_report is initialized
or not. But it seems that in include/linux/timer.h, we can't find a
good function to check the status of this timer, so this patch just
move the initializtion of s_err_report earlier so that we can avoid
the kernel panic. The corresponding del_timer is also added in the
error path.

When KVM scans the 0xD CPUID leaf for propagating the XSAVE save area
leaves, it assumes that the leaves are contigious and stops at the
first zero one. On AMD hardware there is a gap, though, as LWP uses
leaf 62 to announce it's state save area.
So lets iterate through all 64 possible leaves and simply skip zero
ones to also cover later features.

Subject: KVM: move and fix substitue search for missing CPUID entries

If KVM cannot find an exact match for a requested CPUID leaf, the
code will try to find the closest match instead of simply confessing
it's failure.
The implementation was meant to satisfy the CPUID specification, but
did not properly check for extended and standard leaves and also
didn't account for the index subleaf.
Beside that this rule only applies to CPUID intercepts, which is not
the only user of the kvm_find_cpuid_entry() function.

So fix this algorithm and call it from kvm_emulate_cpuid().
This fixes a crash of newer Linux kernels as KVM guests on
AMD Bulldozer CPUs, where bogus values were returned in response to
a CPUID intercept.

The evdev buffer isn't big enough when you get many fingers on the
device. Bump up the buffer to a reasonable size, matching what other
multitouch devices use. Without this change, events may be discarded in
the evdev buffer before they are read.

Subject: Revert "net/sunrpc: Use static const char arrays"

This reverts commit 411b5e05617593efebc06241dbc56f42150f2abe.

Olga Kornievskaia reports:

Problem: linux client mounting linux server using rc4-hmac-md5
enctype. gssd fails with create a context after receiving a reply from
the server.

Diagnose: putting printout statements in the server kernel and
kerberos libraries revealed that client and server derived different
integrity keys.

Server kernel code was at fault due the the commit

[aglo@skydive linux-pnfs]$ git show 411b5e05617593efebc06241dbc56f42150f2abe

Trond: The problem is that since it relies on virt_to_page(), you cannot
call sg_set_buf() for data in the const section.

Subject: ARM: arch-shmobile: only run HDMI init on respective boards

If several boards are enabled in the kernel configuration,
hdmi_init_pm_clock() functions from board-ap4evb.c and board-mackerel.c
will run on any of them. Prevent this by calling these functions from the
.init_machine() callback instead of using device_initcall().

Subject: ARM: arch-shmobile: only run FSI init on respective boards

If several boards are enabled in the kernel configuration,
fsi_init_pm_clock() functions from board-ap4evb.c
will run on any of them. Prevent this by calling these functions from the
.init_machine() callback instead of using device_initcall().

Subject: can: mcp251x: Allow pass IRQ flags through platform data.

When an interrupt occurs, the INT pin is driven low by the
MCP251x controller (falling edge) but in some cases the INT
pin can be connected to the MPU through a transistor or level
translator which inverts this signal. In this case interrupt
should be configured in rising edge.

This patch adds support to pass the IRQ flags via
mcp251x_platform_data.

Subject: ipv6: Enable RFS sk_rxhash tracking for ipv6 sockets (v2)

properly record sk_rxhash in ipv6 sockets (v2)

Noticed while working on another project that flows to sockets which I had open
on a test systems weren't getting steered properly when I had RFS enabled.
Looking more closely I found that:

1) The affected sockets were all ipv6
2) They weren't getting steered because sk->sk_rxhash was never set from the
incomming skbs on that socket.

This was occuring because there are several points in the IPv4 tcp and udp code
which save the rxhash value when a new connection is established.  Those calls
to sock_rps_save_rxhash were never added to the corresponding ipv6 code paths.
This patch adds those calls.  Tested by myself to properly enable RFS
functionalty on ipv6.

Change notes:
v2:
	Filtered UDP to only arm RFS on bound sockets (Eric Dumazet)

Restore the initialization of mmu_cr4_features during boot, which was
removed without comment in checkin e5f15b45ddf3afa2bbbb10c7ea34fb32b6de0a0e

x86: Cleanup highmap after brk is concluded

thereby breaking resume from hibernate.  This restores previous
functionality in approximately the same place, and corrects the
reading of %cr4 on pre-CPUID hardware (%cr4 exists if and only if
CPUID is supported.)

However, part of the problem is that the hibernate suspend/resume
sequence should manage the save/restore of %cr4 explicitly.

Subject: dsa/mv88e6131: add support for mv88e6085 switch

The mv88e6085 is identical to the mv88e6095, except that all ports are
10/100 Mb/s, so use the existing setup code except for the cpu/dsa speed
selection in _setup_port().

After Quick Migration, the network is not immediately operational in the

another netif_notify_peers() into a scheduled work, otherwise GARP packet will
not be sent after quick migration, and cause network disconnection.

Thanks to Mike Surcouf <mike@surcouf.co.uk> for reporting the bug and
testing the patch.

Subject: staging: usbip: bugfix add number of packets for isochronous frames

The number_of_packets was not transmitted for RET_SUBMIT packets. The
linux client used the stored number_of_packet from the submitted
request. The windows userland client does not do this however and needs
to know the number_of_packets to determine the size of the transmission.

Subject: staging: usbip: bugfix for isochronous packets and optimization

For isochronous packets the actual_length is the sum of the actual
length of each of the packets, however between the packets might be
padding, so it is not sufficient to just send the first actual_length
bytes of the buffer. To fix this and simultanesouly optimize the
bandwidth the content of the isochronous packets are send without the
padding, the padding is restored on the receiving end.

Subject: rtc, x86/mrst/vrtc: Fix boot crash in rtc_read_alarm()

Commit f44f7f96a20 ("RTC: Initialize kernel state from RTC") caused a
boot regression on the MRST platform.

The reason is that rtc_device_register() calls rtc_read_alarm() after
that change, which function does not have all driver data set up yet.

The rtc-mrst driver needs to call dev_set_drvdata() before rtc_device_register()
gets called.

Subject: x86/mrst/vrtc: Fix boot crash in mrst_rtc_init()

The sfi_mrtc_array[] only gets initialized when the sfi mrtc
table is parsed, so the vrtc_paddr should be initalized after it
too.

Subject: ALSA: hda - HDMI: Fix MCP7x audio infoframe checksums

The MCP7x hardware computes the audio infoframe channel count
automatically, but requires the audio driver to set the audio
infoframe checksum manually via the Nv_VERB_SET_Info_Frame_Checksum
control verb.

When audio starts playing, nvhdmi_8ch_7x_pcm_prepare sets the checksum
to (0x71 - chan - chanmask).  For example, for 2ch audio, chan == 1
and chanmask == 0 so the checksum is set to 0x70.  When audio playback
finishes and the device is closed, nvhdmi_8ch_7x_pcm_close resets the
channel formats, causing the channel count to revert to 8ch.  Since
the checksum is not reset, the hardware starts generating audio
infoframes with invalid checksums.  This causes some displays to blank
the video.

Fix this by updating the checksum and channel mask when the device is
closed and also when it is first initialized.  In addition, make sure
that the channel mask is appropriate for an 8ch infoframe by setting
it to 0x13 (FL FR LFE FC RL RR RLC RRC).

Subject: mm: avoid wrapping vm_pgoff in mremap()

The normal mmap paths all avoid creating a mapping where the pgoff
inside the mapping could wrap around due to overflow.  However, an
expanding mremap() can take such a non-wrapping mapping and make it
bigger and cause a wrapping condition.

Noticed by Robert Swiecki when running a system call fuzzer, where it
caused a BUG_ON() due to terminally confusing the vma_prio_tree code.  A
vma dumping patch by Hugh then pinpointed the crazy wrapped case.

There's a race condition in stop_queue() in some drivers -
if drv_data->queue is empty, but drv_data->busy is still set
(or opposite situation) stop_queue will return -EBUSY.
So fix loop condition to check that both drv_data->queue is empty
and drv_data->busy is not set.

This patch affects following drivers:
pxa2xx_spi
spi_bfin5xx

Commit 1018b5c01636c7c6bda31a719bda34fc631db29a ("Set rt->rt_iif more
sanely on output routes.")  breaks rt_is_{output,input}_route.

This became the cause to return "IP_PKTINFO's ->ipi_ifindex == 0".

To fix it, this does:

1) Add "int rt_route_iif;" to struct rtable

2) For input routes, always set rt_route_iif to same value as rt_iif

3) For output routes, always set rt_route_iif to zero.  Set rt_iif
   as it is done currently.

4) Change rt_is_{output,input}_route() to test rt_route_iif

Subject: xfs: fix extent format buffer allocation size

When formatting an inode item, we have to allocate a separate buffer
to hold extents when there are delayed allocation extents on the
inode and it is in extent format. The allocation size is derived
from the in-core data fork representation, which accounts for
delayed allocation extents, while the on-disk representation does
not contain any delalloc extents.

As a result of this mismatch, the allocated buffer can be far larger
than needed to hold the real extent list which, due to the fact the
inode is in extent format, is limited to the size of the literal
area of the inode. However, we can have thousands of delalloc
extents, resulting in an allocation size orders of magnitude larger
than is needed to hold all the real extents.

Fix this by limiting the size of the buffer being allocated to the
size of the literal area of the inodes in the filesystem (i.e. the
maximum size an inode fork can grow to).

Subject: xfs: introduce a xfssyncd workqueue

All of the work xfssyncd does is background functionality. There is
no need for a thread per filesystem to do this work - it can al be
managed by a global workqueue now they manage concurrency
effectively.

Introduce a new gglobal xfssyncd workqueue, and convert the periodic
work to use this new functionality. To do this, use a delayed work
construct to schedule the next running of the periodic sync work
for the filesystem. When the sync work is complete, queue a new
delayed work for the next running of the sync work.

For laptop mode, we wait on completion for the sync works, so ensure
that the sync work queuing interface can flush and wait for work to
complete to enable the work queue infrastructure to replace the
current sequence number and wakeup that is used.

Because the sync work does non-trivial amounts of work, mark the
new work queue as CPU intensive.

Subject: xfs: convert ENOSPC inode flushing to use new syncd workqueue

On of the problems with the current inode flush at ENOSPC is that we
queue a flush per ENOSPC event, regardless of how many are already
queued. Thi can result in    hundreds of queued flushes, most of
which simply burn CPU scanned and do no real work. This simply slows
down allocation at ENOSPC.

We really only need one active flush at a time, and we can easily
implement that via the new xfs_syncd_wq. All we need to do is queue
a flush if one is not already active, then block waiting for the
currently active flush to complete. The result is that we only ever
have a single ENOSPC inode flush active at a time and this greatly
reduces the overhead of ENOSPC processing.

On my 2p test machine, this results in tests exercising ENOSPC
conditions running significantly faster - 042 halves execution time,
083 drops from 60s to 5s, etc - while not introducing test
regressions.

This allows us to remove the old xfssyncd threads and infrastructure
as they are no longer used.

Subject: xfs: introduce background inode reclaim work

Background inode reclaim needs to run more frequently that the XFS
syncd work is run as 30s is too long between optimal reclaim runs.
Add a new periodic work item to the xfs syncd workqueue to run a
fast, non-blocking inode reclaim scan.

Background inode reclaim is kicked by the act of marking inodes for
reclaim.  When an AG is first marked as having reclaimable inodes,
the background reclaim work is kicked. It will continue to run
periodically untill it detects that there are no more reclaimable
inodes. It will be kicked again when the first inode is queued for
reclaim.

To ensure shrinker based inode reclaim throttles to the inode
cleaning and reclaim rate but still reclaim inodes efficiently, make it kick the
background inode reclaim so that when we are low on memory we are
trying to reclaim inodes as efficiently as possible. This kick shoul
d not be necessary, but it will protect against failures to kick the
background reclaim when inodes are first dirtied.

To provide the rate throttling, make the shrinker pass do
synchronous inode reclaim so that it blocks on inodes under IO. This
means that the shrinker will reclaim inodes rather than just
skipping over them, but it does not adversely affect the rate of
reclaim because most dirty inodes are already under IO due to the
background reclaim work the shrinker kicked.

These two modifications solve one of the two OOM killer invocations
Chris Mason reported recently when running a stress testing script.
The particular workload trigger for the OOM killer invocation is
where there are more threads than CPUs all unlinking files in an
extremely memory constrained environment. Unlike other solutions,
this one does not have a performance impact on performance when
memory is not constrained or the number of concurrent threads
operating is <= to the number of CPUs.

Subject: xfs: convert the xfsaild threads to a workqueue

Similar to the xfssyncd, the per-filesystem xfsaild threads can be
converted to a global workqueue and run periodically by delayed
works. This makes sense for the AIL pushing because it uses
variable timeouts depending on the work that needs to be done.

By removing the xfsaild, we simplify the AIL pushing code and
remove the need to spread the code to implement the threading
and pushing across multiple files.

Subject: xfs: clean up code layout in xfs_trans_ail.c

This patch rearranges the location of functions in xfs_trans_ail.c
to remove the need for forward declarations of those functions in
preparation for adding new functions without the need for forward
declarations.

Subject: xfs: push the AIL from memory reclaim and periodic sync

When we are short on memory, we want to expedite the cleaning of
dirty objects.  Hence when we run short on memory, we need to kick
the AIL flushing into action to clean as many dirty objects as
quickly as possible.  To implement this, sample the lsn of the log
item at the head of the AIL and use that as the push target for the
AIL flush.

Further, we keep items in the AIL that are dirty that are not
tracked any other way, so we can get objects sitting in the AIL that
don't get written back until the AIL is pushed. Hence to get the
filesystem to the idle state, we might need to push the AIL to flush
out any remaining dirty objects sitting in the AIL. This requires
the same push mechanism as the reclaim push.

This patch also renames xfs_trans_ail_tail() to xfs_ail_min_lsn() to
match the new xfs_ail_max_lsn() function introduced in this patch.
Similarly for xfs_trans_ail_push -> xfs_ail_push.

Subject: xfs: catch bad block numbers freeing extents.

A fuzzed filesystem crashed a kernel when freeing an extent with a
block number beyond the end of the filesystem. Convert all the debug
asserts in xfs_free_extent() to active checks so that we catch bad
extents and return that the filesytsem is corrupted rather than
crashing.

Subject: xfs: convert log tail checking to a warning

On the Power platform, the log tail debug checks fire excessively
causing the system to panic early in testing. The debug checks are
known to be racy, though on x86_64 there is no evidence that they
trigger at all.

We want to keep the checks active on debug systems to alert us to
problems with log space accounting, but we need to reduce the impact
of a racy check on testing on the Power platform.

As a result, convert the ASSERT conditions to warnings, and
allow them to fire only once per filesystem mount. This will prevent
false positives from interfering with testing, whilst still
providing us with the indication that they may be a problem with log
space accounting should that occur.

Subject: xfs: fix xfs_debug warnings

For a CONFIG_XFS_DEBUG=n build gcc complains about statements with no
effect in xfs_debug:

fs/xfs/quota/xfs_qm_syscalls.c: In function 'xfs_qm_scall_trunc_qfiles':
fs/xfs/quota/xfs_qm_syscalls.c:291:3: warning: statement with no effect

The reason for that is that the various new xfs message functions have a
return value which is never used, and in case of the non-debug build
xfs_debug the macro evaluates to a plain 0 which produces the above
warnings.  This can be fixed by turning xfs_debug into an inline function
instead of a macro, but in addition to that I've also changed all the
message helpers to return void as we never use their return values.

Subject: xfs: use proper interfaces for on-stack plugging

Add proper blk_start_plug/blk_finish_plug pairs for the two places where
we issue buffer I/O, and remove the blk_flush_plug in xfs_buf_lock and
xfs_buf_iowait, given that context switches already flush the per-process
plugging lists.

Subject: ext4: sync the directory inode in ext4_sync_parent()

ext4 has taken the stance that, in the absence of a journal,
when an fsync/fdatasync of an inode is done, the parent
directory should be sync'ed if this inode entry is new.
ext4_sync_parent(), which implements this, does indeed sync
the dirent pages for parent directories, but it does not
sync the directory *inode*.  This patch fixes this.

Also now return error status from ext4_sync_parent().

I tested this using a power fail test, which panics a
machine running a file server getting requests from a
client.  Without this patch, on about every other test run,
the server is missing many, many files that had been synced.
With this patch, on > 6 runs, I see zero files being lost.

 size

We can create 4402345721856 byte file with indirect block mapping.
However, if we grow an indirect-block file to the size with ftruncate(),
we can see an ext4 warning. The following patch fixes this problem.

How to reproduce:

Subject: pci: fix PCI bus allocation alignment handling

In commit 13583b16592a ("PCI: refactor io size calculation code") Ram
had a thinko in the refactorization of the code: the end result used the
variable 'align' for the bus alignment, but the original code used
'min_align'.

Since then, another use of that 'align' variable got introduced by
commit c8adf9a3e873 ("PCI: pre-allocate additional resources to devices
only after successful allocation of essential resources.")

Fix both of those uses to use 'min_align' as they should.
