Pull spi updates from Mark Brown:
"A fairly quiet release for the SPI subsystem, the standout changes
being:
- Core support for implementing bits per word constraints implemented
by Stephen Warren, factoring some code out of drivers.
- Addition of polling mode support for the s3c64xx driver as some
newer Exynos systems have taken the unusual step of removing
interrupt support.
- Use of the in-IP FIFO and generic dmaengine support for the OMAP2
driver, providing improved performance.
- Conversion of the mpc512x driver to use the core message queue
infrastructure.
The nicest thing being that all the factoring out into common code
leads to a negative diffstat overall."

Pull pin control changes from Linus Walleij:
- A large slew of improvements of the Genric pin configuration support,
and deployment in four different platforms: Rockchip, Super-H PFC,
ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing
and debugfs support into shape.
- We also have device tree support with generic naming conventions for
the generic pin configuration.
- Delete the unused and confusing direct pinconf API. Now state
transitions is *the* way to control pins and multiplexing.
- New drivers for Rockchip, TZ1090, and TZ1090 PDC.
- Two pin control states related to power management are now handled in
the device core: "sleep" and "idle", removing a lot of boilerplate
code in drivers. We do not yet know if this is the final word for
pin PM, but it already make things a lot easier to handle.
- Handle sparse GPIO ranges passing a list of disparate pins, and
utilize these in the new BayTrail (x86 Atom SoC) driver.
- Make the sunxi (AllWinner) driver handle external interrupts.
- Make it possible for pinctrl-single to handle the case where several
pins are managed by a single register, and augment it to handle sleep
modes.
- Cleanups and improvements for the abx500 drivers.
- Move Sirf pin control drivers to their own directory, support
save/restore of context and add support for the SiRFatlas6 SoC.
- PMU muxing for the Dove pinctrl driver.
- Finalization and support for VF610 in the i.MX6 pinctrl driver.
- Smoothen out various Exynos rough edges.
- Generic cleanups of various kinds.

Pull regmap updates from Mark Brown:
"A small but useful set of regmap updates this time around:
- An abstraction for bitfields within a register map contributed by
Srinivas Kandagatla, allowing drivers to cope more easily when
hardware designers randomly move things about (mainly when talking
to things like system controllers).
- Changes from Lars-Peter Clausen to allow the MMIO regmap to be used
from hard IRQ context.
- Small improvements to the cache infrastructure and performance,
including a default cache sync operation so now all regmaps can
sync easily.
There's also a pinctrl driver making use of the new bitfield API,
merged here for dependency reasons. There will be a simple add/add
conflict with the pinctrl tree as a result."

- R7 Support
- MPU support
I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
were discussing today until we've reached a conclusion/that's had
some more review.
This is rebased (and re-tested) on your devel-stable branch because
otherwise there were going to be conflicts with Uwe's V7M work now
that you've merged that. I've included the fix for limiting MPU to
CPU_V7.
- Huge page support
These changes bring both HugeTLB support and Transparent HugePage
(THP) support to ARM. Only long descriptors (LPAE) are supported
in this series.
The code has been tested on an Arndale board (Exynos 5250).
- LPAE updates
Please pull these miscellaneous LPAE fixes I've been collecting for
a while now for 3.11. They've been tested and reviewed by quite a
few people, and most of the patches are pretty trivial. -- Will Deacon.
- arch_timer cleanups
Please pull these arch_timer cleanups I've been holding onto for a
while. They're the same as my last posting, but have been rebased
to v3.10-rc3.
- mpidr linearisation (multiprocessor id register - identifies which
CPU number we are in the system)
This patch series that implements MPIDR linearization through a
simple hashing algorithm and updates current cpu_{suspend}/{resume}
code to use the newly created hash structures to retrieve context
pointers. It represents a stepping stone for the implementation of
power management code on forthcoming multi-cluster ARM systems.
It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
OMAP4 and Tegra, with processors hitting low-power states requiring
warm-boot resume through the cpu_resume code path"

Genius Gila Gaming Mouse presents an obviously wrong report descriptor.
the Consumer control (report ID 3) is the following:
0x05, 0x0c, // Usage Page (Consumer Devices) 105
0x09, 0x01, // Usage (Consumer Control) 107
0xa1, 0x01, // Collection (Application) 109
0x85, 0x03, // Report ID (3) 111
0x19, 0x00, // Usage Minimum (0) 113
0x2a, 0xff, 0x7f, // Usage Maximum (32767) 115
0x15, 0x00, // Logical Minimum (0) 118
0x26, 0xff, 0x7f, // Logical Maximum (32767) 120
0x75, 0x10, // Report Size (16) 123
0x95, 0x03, // Report Count (3) 125
0x81, 0x00, // Input (Data,Arr,Abs) 127
0x75, 0x08, // Report Size (8) 129
0x95, 0x01, // Report Count (1) 131
0x81, 0x01, // Input (Cnst,Arr,Abs) 133
0xc0, // End Collection 135
So the first input whithin this report has a count of 3 but a usage range
of 32768. So this value is obviously wrong as it should not be greater than
the report count.

For those file systems(btrfs/ext4/ocfs2/tmpfs) that support
SEEK_DATA/SEEK_HOLE functions, we end up handling the similar
matter in lseek_execute() to update the current file offset
to the desired offset if it is valid, ceph also does the
simliar things at ceph_llseek().
To reduce the duplications, this patch make lseek_execute()
public accessible so that we can call it directly from the
underlying file systems.
Thanks Dave Chinner for this suggestion.
[AV: call it vfs_setpos(), don't bring the removed 'inode' argument back]

Pull cpuset changes from Tejun Heo:
"cpuset has always been rather odd about its configurations - a cgroup
right after creation didn't allow any task executions before
configuration, changing configuration in the parent modifies the
descendants irreversibly and so on. These behaviors are inherently
nasty and almost hostile against sharing the hierarchy with other
controllers making it very difficult to use in unified hierarchy.
Li is currently in the process of updating the behaviors for
__DEVEL__sane_behavior which is the bulk of changes in this pull
request. It isn't complete yet and the behaviors will change further
but all changes are gated behind sane_behavior. In the process, the
rather hairy work-item punting which was used to work around the
limitations of cgroup descendant iterator was simplified."

Pull cgroup changes from Tejun Heo:
"This pull request contains the following changes.
- cgroup_subsys_state (css) reference counting has been converted to
percpu-ref. css is what each resource controller embeds into its
own control structure and perform reference count against. It may
be used in hot paths of various subsystems and is similar to module
refcnt in that aspect. For example, block-cgroup's css refcnting
was showing up a lot in Mikulaus's device-mapper scalability work
and this should alleviate it.
- cgroup subtree iterator has been updated so that RCU read lock can
be released after grabbing reference. This allows simplifying its
users which requires blocking which used to build iteration list
under RCU read lock and then traverse it outside. This pull
request contains simplification of cgroup core and device-cgroup.
A separate pull request will update cpuset.
- Fixes for various bugs including corner race conditions and RCU
usage bugs.
- A lot of cleanups and some prepartory work for the planned unified

libata/for-3.10-fixes never got submitted during v3.10 cycle. Merge
it into for-3.11 so that it can be routed together with other changes
scheduled for v3.11.
Three trivial conflicts in drivers/ata/sata_rcar.c. All are caused by
1b20f6a9ad ("sata_rcar: add 'base' local variable to some functions")
conflicting with logic updates in for-3.10-fixes. The offending
commit simply adds local variable @base on functions which
dereferences sata_rcar_priv->base multiple times. The resolutions are
trivial - applying s/priv->base/base/ in the conflicting logic
updates.

Pull workqueue changes from Tejun Heo:
"Surprisingly, Lai and I didn't break too many things implementing
custom pools and stuff last time around and there aren't any follow-up
changes necessary at this point.
The only change in this pull request is Viresh's patches to make some
per-cpu workqueues to behave as unbound workqueues dependent on a boot
param whose default can be configured via a config option. This leads
to higher processing overhead / lower bandwidth as more work items are
bounced across CPUs; however, it can lead to noticeable powersave in
certain configurations - ~10% w/ idlish constant workload on a
big.LITTLE configuration according to Viresh.
This is because per-cpu workqueues interfere with how the scheduler
perceives whether or not each CPU is idle by forcing pinned tasks on
them, which makes the scheduler's power-aware scheduling decisions
less effective.
Its effectiveness is likely less pronounced on homogenous
configurations and this type of optimization can probably be made
automatic; however, the changes are pretty minimal and the affected
workqueues are clearly marked, so it's an easy gain for some
configurations for the time being with pretty unintrusive changes."

The usual usage is relatively straight-forward although async kill

There also are some interface concerns - e.g. I'm not sure about
passing in @relesae callback during init as that becomes funny when we
later implement synchronous kill_and_drain - but nothing too serious
and it's quite useable now.

1/ If a RAID10 is being reshaped to a fewer number of devices
and is stopped while this is ongoing, then when the array is
reassembled the 'mirrors' array will be allocated too small.
This will lead to an access error or memory corruption.
2/ A sanity test for a reshaping RAID10 array is restarted
is slightly incorrect.
Due to the first bug, this is suitable for any -stable
kernel since 3.5 where this code was introduced.
