Pull x86 platform drivers fixes from Darren Hart:
"This is my first pull request since taking on maintenance for the
platform-drivers-x86 tree from Matthew Garrett. These have passed my
build testing and been run through Fengguang's LKP tests. Due to
timing this round, these have not spent any time in linux-next. I
have asked Stephen to include my for-next branch in linux-next going
forward, once he's back from vacation.
Details from tag:
- toshiba_acpi: re-enable hotkeys and cleanups
- ideapad-laptop: revert touchpad disable, and cleanup static/const
usage
- MAINTAINERS: update platform-drivers-x86 maintainer and tree"

Pull regmap fixes from Mark Brown:
"Several bug fixes for issues that have been lurking for a while:
- Check that devices haven't set the flag saying they only support
register at a time operation while we're doing cache syncs,
otherwise we fail to restore caches
- Ensure that we don't mark all registers on devices using
format_write() as cacheable, avoiding adding a cache of things like
reset registers which we don't want to rewrite during cache sync
- Make sure we create the debugfs files in the correct directory"

The current code just returns -EINVAL because mode can't be equal to
both 1 and 2.
Also this function is messy so I have cleaned it up:
1) Remove initializers like "int time = -1". Initializing variables to
garbage values turns off GCC's uninitialized variable warnings so it
can lead to bugs.
2) Use kstrtoint() instead of sscanf().
3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1
and 2.
4) Don't check for "mode == -1" because that can't happen.
5) Preserve the error code from toshiba_kbd_illum_status_set().

Pull more arm64 fixes from Will Deacon:
"Another handful of arm64 fixes here. They address some issues found
by running smatch on the arch code (ignoring the false positives) and
also stop 32-bit Android from losing track of its stack.
There's one additional irq migration fix in the pipeline, but it came
in after I'd tagged and tested this set.
- a few fixes for real issues found by smatch (after Dan's talk at KS)
- revert the /proc/cpuinfo changes merged during the merge window.
We've opened a can of worms here, so we need to find out where we
stand before we change this interface.

Relax the check on the length of the PKCS#7 cert as it appears that the PE
file wrapper size gets rounded up to the nearest 8.
The debugging output looks like this:
PEFILE: ==> verify_pefile_signature()
PEFILE: ==> pefile_parse_binary()
PEFILE: checksum @ 110
PEFILE: header size = 200
PEFILE: cert = 968 @547be0 [68 09 00 00 00 02 02 00 30 82 09 56 ]
PEFILE: sig wrapper = { 968, 200, 2 }
PEFILE: Signature data not PKCS#7
The wrapper is the first 8 bytes of the hex dump inside []. This indicates a
length of 0x968 bytes, including the wrapper header - so 0x960 bytes of
payload.
The ASN.1 wrapper begins [ ... 30 82 09 56 ]. That indicates an object of size
0x956 - a four byte discrepency, presumably just padding for alignment
purposes.
So we just check that the ASN.1 container is no bigger than the payload and
reduce the recorded size appropriately.
Whilst we're at it, allow shorter PKCS#7 objects that manage to squeeze within
127 or 255 bytes. It's just about conceivable if no X.509 certs are included
in the PKCS#7 message.

This is a follow-up patch to commit 49458e83082d ("ideapad-laptop:
Constify DMI table and other r/o variables") to do what its commit
message says. The actual commit differs from the patch posted at
https://www.mail-archive.com/[email protected]/msg05340.html
significantly, probably due to a bad merge conflict resolution. Fix up
the mess and constify the DMI table for real and fix the bogus
double-const of ideapad_rfk_data[].

This reverts commit 8b37e1bef5a6b60e949e28a4db3006e4b00bd758.
It's broken as it changes led_blink_set() in a way that it can now sleep
(while synchronously waiting for workqueue to be cancelled). That's a
problem, because it's possible that this function gets called from atomic
context (tpt_trig_timer() takes a readlock and thus disables preemption).
This has been brought up 3 weeks ago already [1] but no proper fix has
materialized, and I keep seeing the problem since 3.17-rc1.

As the race condition on the inode cache, following scenario can appear:
[Thread a] [Thread b]
->f2fs_mkdir
->f2fs_add_link
->__f2fs_add_link
->init_inode_metadata failed here
->gc_thread_func
->f2fs_gc
->do_garbage_collect
->gc_data_segment
->f2fs_iget
->iget_locked
->wait_on_inode
->unlock_new_inode
->move_data_page
->make_bad_inode
->iput
When we fail in create/symlink/mkdir/mknod/tmpfile, the new allocated inode
should be set as bad to avoid being accessed by other thread. But in above
scenario, it allows f2fs to access the invalid inode before this inode was set
as bad.
This patch fix the potential problem, and this issue was found by code review.

It turns out that vendors are relying on the format of /proc/cpuinfo,
and we've even spotted out-of-tree hacks attempting to make it look
identical to the format used by arch/arm/. That means we can't afford to
churn this interface in mainline, so revert the recent reformatting of
the file for arm64 pending discussions on the list to find out what
people actually want.

Now arm64 defers reloading FPSIMD state, but this optimization also
introduces the bug after cpu resume back from low power mode.
The reason is after the cpu has been powered off, s/w need set the
cpu's fpsimd_last_state to NULL so that it will force to reload
FPSIMD state for the thread, otherwise there has the chance to meet
the condition for both the task's fpsimd_state.cpu field contains the
id of the current cpu, and the cpu's fpsimd_last_state per-cpu variable
points to the task's fpsimd_state, so finally kernel will skip to reload
the context during it return back to userland.

Pull ARM SoC fixes from Olof Johansson:
"Here's the weekly batch of fixes from arm-soc.
The delta is a largeish negative delta, due to revert of SMP support
for Broadcom's STB SoC -- it was accidentally merged before some
issues had been addressed, so they will make a new attempt for 3.18.
I didn't see a need for a full revert of the whole platform due to
this, we're keeping the rest enabled.
The rest is mostly:
- a handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
- some MTD/NAND fixes for OMAP
- minor DT fixes for shmobile
- warning fix for UP builds on vexpress/spc
There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
so it can boot. Drivers and the rest had landed for 3.17, and it's
small and isolated so it made sense to pick up now even if it's not a
bugfix"
