"Here are several fixes for filesystems with CRC support turned on:
fixes for quota, remote attributes, and recovery. There is also some
feature work related to CRCs: the implementation of CRCs for the inode
unlinked lists, disabling noattr2/attr2 options when appropriate, and
bumping the maximum number of ACLs.
I would have preferred to defer this last category of items to 3.11.
This would require setting a feature bit for the on-disk changes, so
there is some pressure to get these in 3.10. I believe this
represents the end of the CRC related queue.

(cherry picked from commit d3eaace84e)
When in an active transaction that takes a signal, we need to be careful with
the stack. It's possible that the stack has moved back up after the tbegin.
The obvious case here is when the tbegin is called inside a function that
returns before a tend. In this case, the stack is part of the checkpointed
transactional memory state. If we write over this non transactionally or in
suspend, we are in trouble because if we get a tm abort, the program counter
and stack pointer will be back at the tbegin but our in memory stack won't be
valid anymore.
To avoid this, when taking a signal in an active transaction, we need to use
the stack pointer from the checkpointed state, rather than the speculated
state. This ensures that the signal context (written tm suspended) will be
written below the stack required for the rollback. The transaction is aborted
becuase of the treclaim, so any memory written between the tbegin and the
signal will be rolled back anyway.
For signals taken in non-TM or suspended mode, we use the
normal/non-checkpointed stack pointer.
Tested with 64 and 32 bit signals

If we are emulating an instruction inside an active user transaction that
touches memory, the kernel can't emulate it as it operates in transactional
suspend context. We need to abort these transactions and send them back to
userspace for the hardware to rollback.
We can service these if the user transaction is in suspend mode, since the
kernel will operate in the same suspend context.
This adds a check to all alignment faults and to specific instruction
emulations (only string instructions for now). If the user process is in an
active (non-suspended) transaction, we abort the transaction go back to
userspace allowing the HW to roll back the transaction and tell the user of the
failure. This also adds new tm abort cause codes to report the reason of the
persistent error to the user.

A simple frame-buffer describes a raw memory region that may be rendered
to, with the assumption that the display hardware has already been set
up to scan out from that buffer.
This is useful in cases where a bootloader exists and has set up the
display hardware, but a Linux driver doesn't yet exist for the display
hardware.
Examples use-cases include:
* The built-in LCD panels on the Samsung ARM chromebook, and Tegra
devices, and likely many other ARM or embedded systems. These cannot
yet be supported using a full graphics driver, since the panel control
should be provided by the CDF (Common Display Framework), which has been
stuck in design/review for quite some time. One could support these
panels using custom SoC-specific code, but there is a desire to use
common infra-structure rather than having each SoC vendor invent their
own code, hence the desire to wait for CDF.
* Hardware for which a full graphics driver is not yet available, and
the path to obtain one upstream isn't yet clear. For example, the
Raspberry Pi.
* Any hardware in early stages of upstreaming, before a full graphics
driver has been tackled. This driver can provide a graphical boot
console (even full X support) much earlier in the upstreaming process,
thus making new SoC or board support more generally useful earlier.

A collection of fixes for fall out from 3.10 merge window, some build
fixes and warning cleanups and a small handful of patches that were
small and contained and made sense to still include in 3.10 (some of
these have also been in -next since the merge window opened).
Largest continous series is for OMAP, but there's a handful for other
platforms.
For i.MX, one of the patches are framebuffer fixups due to fallout during
the merge window, and the other removes some stale and broken code.

Pull btrfs update from Chris Mason:
"These are mostly fixes. The biggest exceptions are Josef's skinny
extents and Jan Schmidt's code to rebuild our quota indexes if they
get out of sync (or you enable quotas on an existing filesystem).
The skinny extents are off by default because they are a new variation
on the extent allocation tree format. btrfstune -x enables them, and
the new format makes the extent allocation tree about 30% smaller.
I rebased this a few days ago to rework Dave Sterba's crc checks on
the super block, but almost all of these go back to rc6, since I
though 3.9 was due any minute.
The biggest missing fix is the tracepoint bug that was hit late in
3.9. I ran into problems with that in overnight testing and I'm still
tracking it down. I'll definitely have that fixed for rc2."

GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
possible to do so which has been causing confusion and breakage. This
branch does the work to completely eliminate GENERIC_GPIO.
However, it is not trivial to just create a branch to remove it. Over
the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
added to linux-next that conflicts with this branch. The following must
be done to resolve the conflicts when merging this branch into mainline:
* "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
replaced with CONFIG_GPIOLIB
* "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
documentation.
* Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
* definitions of the option in architecture Kconfig code should be deleted.
Stephen has 3 merge fixup patches[1] that do the above. They are currently
applicable on mainline as of May 2nd.

Merge more incoming from Andrew Morton:
- Various fixes which were stalled or which I picked up recently
- A large rotorooting of the AIO code. Allegedly to improve
performance but I don't really have good performance numbers (I might
have lost the email) and I can't raise Kent today. I held this out
of 3.9 and we could give it another cycle if it's all too late/scary.
I ended up taking only the first two thirds of the AIO rotorooting. I
left the percpu parts and the batch completion for later. - Linus

This exports the amount of anonymous transparent hugepages for each
memcg via the new "rss_huge" stat in memory.stat. The units are in
bytes.
This is helpful to determine the hugepage utilization for individual
jobs on the system in comparison to rss and opportunities where
MADV_HUGEPAGE may be helpful.
The amount of anonymous transparent hugepages is also included in "rss"
for backwards compatibility.

Patchwork: http://patchwork.linux-mips.org/patch/5187/
These continue the multiplatform support for exynos, adding support
for building most of the essential drivers (clocksource, clk, irqchip)
when combined with other platforms. As a result, it should become
really easy to add full multiplatform exynos support in 3.11, although
we don't yet enable it for 3.10.
The changes were not included in the earlier multiplatform series
in order to avoid clashes with the other Exynos updates.
This also includes work from Tomasz Figa to fix the pwm clocksource
code on Exynos, which is not strictly required for multiplatform,
but related to the other patches in this set and needed as a bug
fix for at least one board.
