Pull OMAP specific fbdev changes from Tomi Valkeinen:
"I've got this pull request separate from the main fbdev pull request,
as this contains a bunch of OMAP board file changes and thus could
possibly be rejected in case of bad conflicts.
The removal of the old display drivers depend on the board file
changes, so Tony Lindgren suggested taking them together via fbdev
tree. These are in linux-next, and also Tony didn't see any conflicts
with any of the branches he had, so they should go in clean.
- Change the OMAP board files to use the new OMAP display drivers
- Remove all the old drivers, and the related auxiliary code"

Merge IPMI fixes from:
"A few things for 3.12 from various people"
* emailed patches from Corey Minyard <minyard@acm.org>:
BMC support for PARISC machines
Add MODULE_ALIAS for autoloading ipmi driver on ACPI systems
ipmi: Initialize locals to avoid warning
ipmi: info leak in compat_ipmi_ioctl()
|
|
The last line of PARISC machines (C8000, RP34x0, etc.) have a BMC for
controlling temperature, fan speed and other stuff. The BMC is
connected via a special bus and listed in the firmware device tree.
This change adds support for these BMCs to the IPMI driver.

I'd submitted this about a year ago but it never made it upstream.

Pull Xen updates from Konrad Rzeszutek Wilk:
"A couple of features and a ton of bug-fixes. There is also some
maintership changes. Jeremy is enjoying the full-time work at the
startup and as much as he would love to help - he can't find the time.
I have a bunch of other things that I promised to work on - paravirt
diet, get SWIOTLB working everywhere, etc, but haven't been able to
find the time.
As such both David Vrabel and Boris Ostrovsky have graciously
volunteered to help with the maintership role. They will keep the lid
on regressions, bug-fixes, etc. I will be in the background to help -
but eventually there will be less of me doing the Xen GIT pulls and
more of them. Stefano is still doing the ARM/ARM64 and will continue
on doing so.
Features:
- Xen Trusted Platform Module (TPM) frontend driver - with the
backend in MiniOS.
- Scalability improvements in event channel.
- Two extra Xen co-maintainers (David, Boris) and one going away (Jeremy)
Bug-fixes:
- Make the 1:1 mapping work during early bootup on selective regions.
- Add scratch page to balloon driver to deal with unexpected code
still holding on stale pages.
- Allow NMIs on PV guests (64-bit only)
- Remove unnecessary TLB flush in M2P code.
- Fixes duplicate callbacks in Xen granttable code.
- Fixes in PRIVCMD_MMAPBATCH ioctls to allow retries
- Fix for events being lost due to rescheduling on different VCPUs.
- More documentation"

Pull pin control changes from Linus Walleij:
"Here is the bulk of pin control changes for the v3.12 series. Most of
the relevant information is in the tag.
I merged in v3.11-rc7 last week to get rid of a largeish conflict
within the sunxi (AllWinner) driver in linux-next and fix up the
non-trivial merge the right way. That driver had a rather large fix
adding locking late in the release cycle.
Overall the bulk changes this time is cleanups and refactorings and
not much new features, which is nice.
- Refactorings for generic pin config handling in the core.
- Factor out a set of device tree utilities for use in all drivers,
to parse and allocate maps from the device tree.
- Some fixes to the core such as more nitpicky locking.
- Pushed down config array iteration into the drivers.
This patch is necessary for drivers that want to iterate over
configs and pile up a stack of alterations to the same register(s),
or if the driver wants to take a local spinlock when committing the
configuration.
- A new driver for the Texas Instruments Palmas PMIC by Laxman
Dewangan. This is used on the Tegra systems.
- A major cleanup and modernization of the PFC (Super Hitachi and ARM
SHmobile) pin controller and subdrivers.
- Support for the A20 and A31 sunxi (AllWinner) SoCs.
- A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan
Carpenter, Julia Lawall and Sachin Kamat did an excellent job here"

Pull ACPI and power management updates from Rafael Wysocki:
1) ACPI-based PCI hotplug (ACPIPHP) subsystem rework and introduction
of Intel Thunderbolt support on systems that use ACPI for signalling
Thunderbolt hotplug events. This also should make ACPIPHP work in
some cases in which it was known to have problems. From
Rafael J Wysocki, Mika Westerberg and Kirill A Shutemov.
2) ACPI core code cleanups and dock station support cleanups from
Jiang Liu and Rafael J Wysocki.
3) Fixes for locking problems related to ACPI device hotplug from
Rafael J Wysocki.
4) ACPICA update to version 20130725 includig fixes, cleanups, support
for more than 256 GPEs per GPE block and a change to make the ACPI
PM Timer optional (we've seen systems without the PM Timer in the
field already). One of the fixes, related to the DeRefOf operator,
is necessary to prevent some Windows 8 oriented AML from causing
problems to happen. From Bob Moore, Lv Zheng, and Jung-uk Kim.
5) Removal of the old and long deprecated /proc/acpi/event interface
and related driver changes from Thomas Renninger.
6) ACPI and Xen changes to make the reduced hardware sleep work with
the latter from Ben Guthro.
7) ACPI video driver cleanups and a blacklist of systems that should
not tell the BIOS that they are compatible with Windows 8 (or ACPI
backlight and possibly other things will not work on them). From
Felipe Contreras.
8) Assorted ACPI fixes and cleanups from Aaron Lu, Hanjun Guo,
Kuppuswamy Sathyanarayanan, Lan Tianyu, Sachin Kamat, Tang Chen,
Toshi Kani, and Wei Yongjun.

reduce oscillations between min and max frequencies (essentially,
it causes the governor to choose target frequencies proportional
to load) from Stratos Karafotis.
10) cpufreq fixes allowing sysfs attributes file permissions to be
preserved over suspend/resume cycles Srivatsa S Bhat.
11) Removal of Device Tree parsing for CPU device nodes from multiple
cpufreq drivers that required some changes related to
of_get_cpu_node() to be made in a few architectures and in the
driver core. From Sudeep KarkadaNagesha.
12) cpufreq core fixes and cleanups related to mutual exclusion and
driver module references from Viresh Kumar, Lukasz Majewski and

Pull SCSI target fixes from Nicholas Bellinger:
"The first patch is to address a long standing issue where INQUIRY
vendor + model response data was not correctly padded with ASCII
spaces, causing MSFT and Falconstor multipath stacks to not function
with our LUNs.
The second -> forth patches are additional iscsi-target regression
fixes for the post >= v3.10 iser-target changes. The second and third
are failure cases that have appeared during further testing, and the
forth is only reproducible with malformed NOP packets.
The fifth patch is a v3.11 specific regression caused by a recent
optimization that showed up during WRITE I/O failure testing.
I'll be sending Patch #1 and Patch #5 to Greg-KH separately for

Pull first batch of s390 updates from Martin Schwidefsky:
"The most interesting change is that Martin converted s390 to generic
hardirqs. Which means that all current architectures have been
converted and that CONFIG_GENERIC_HARDIRQS can be removed. Martin
prepared a patch for that already (see genirq branch), but the best
time to merge that is probably at the end of the merge window / begin
of -rc1.
Another patch converts s390 to software referenced bits instead of
relying on the reference bit in the storage key. Therefore s390
doesn't use storage keys anymore, except for kvm.
Besides that we have improvements, cleanups and fixes in PCI, DASD and
all over the place."

Pull regulator updates from Mark Brown:
"Not much exciting going on with the regulator API this time around,
lots of driver fixes and enhancements - the main thing is the addition
of a new API to help make the stubbing code do the right thing for
missing regulator mappings.
Highlights:
- A new regulator_get_optional() API call for regulators that can be
absent in normal operation. This currently does nothing but will
be used to improve the stubbing code for unspecified regulators,
helping avoid some of the issues we've seen with adding new
regulator support.
- Helpers for devices with multiple linear ranges of voltages in the
same regulator.

rather large.

Push file descriptor list locking down to per-device locking. Let sg_index_lock
only protect device lookup.
sdp->detached is also set and checked with this lock held.

@detached is set under the protection of sg_index_lock. Without getting the
lock, new sfp will be added during sg removal and there is no chance for it
to be picked out. So check with sg_index_lock held in sg_add_sfp().

Open exclusive check is protected by o_sem, no need sg_open_exclusive_lock.
@exclude is used to record which type of rwsem we are holding.

A race condition may happen if two threads are both trying to open the same sg
with O_EXCL simultaneously. It's possible that they both find fsds list is
empty and get_exclude(sdp) returns 0, then they both call set_exclude() and
break out from wait_event_interruptible and resume open.
Now use rwsem to protect this process. Exclusive open gets write lock and
others get read lock. The lock will be held until file descriptor is closed.
This also leads 'exclude' only a status rather than a check mark.
