Do not tell people in the Kconfig help when exactly we are going to
remove the deprecated ACPI interfaces in /proc, because, honestly,
we don't know. We will remove them when they are not used any more.
In particular, do not tell them that the interfaces will be removed
in a kernel release that already happened long ago.

Pull x86 fixes from Peter Anvin:
"A somewhat unpleasantly large collection of small fixes. The big ones
are the __visible tree sweep and a fix for 'earlyprintk=efi,keep'. It
was using __init functions with predictably suboptimal results.
Another key fix is a build fix which would produce output that simply
would not decompress correctly in some configuration, due to the
existing Makefiles picking up an unfortunate local label and mistaking
it for the global symbol _end.
Additional fixes include the handling of 64-bit numbers when setting
the vdso data page (a latent bug which became manifest when i386
started exporting a vdso with time functions), a fix to the new MSR
manipulation accessors which would cause features to not get properly
unblocked, a build fix for 32-bit userland, and a few new platform
quirks"

Media force wake get hangs the machine when the system is booted without
displays attached. The assumption is that (at least some versions of)
the firmware has skipped some initialization in that case.
Empirical evidence suggests we need to reset the media force wake
request register in addition to the render one to avoid hangs.

With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit
systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall()
may lose upper bits or, worse, add them since compiler will do this:
(u64)(tk->wall_to_monotonic.tv_nsec << tk->shift)
instead of
((u64)tk->wall_to_monotonic.tv_nsec << tk->shift)
So if, for example, tv_nsec is 0x800000 and shift is 8 we will end up
with 0xffffffff80000000 instead of 0x80000000. And then we are stuck in
the subsequent 'while' loop.
We need an explicit cast.

v2: replace missing break in switch statement (as pointed out by Dave
Jones)
commit bce7560d49 (locks: consolidate checks for compatible
filp->f_mode values in setlk handlers) introduced a regression in the
F_GETLK handler.
flock64_to_posix_lock is a shared codepath between F_GETLK and F_SETLK,
but the f_mode checks should only be applicable to the F_SETLK codepaths
according to POSIX.
Instead of just reverting the patch, add a new function to do this
checking and have the F_SETLK handlers call it.

Commit de7b297390 "tracepoint: Use struct pointer instead of name hash
for reg/unreg tracepoints" introduces a use after free by calling
release_probes on the old struct tracepoint array before the newly
allocated array is published with rcu_assign_pointer. There is a race
window where tracepoints (RCU readers) can perform a
"use-after-grace-period-after-free", which shows up as a GPF in
stress-tests.

The replacement of the 'count' variable by two variables 'incs' and
'decs' to resolve some race conditions during module unloading was done
in parallel with some cleanup in the trace subsystem, and was integrated
as a merge.
Unfortunately, the formula for this replacement was wrong in the tracing
code, and the refcount in the traces was not usable as a result.
Use 'count = incs - decs' to compute the user count.

acpi_processor_add() assumes that present at boot CPUs
are always onlined, it is not so if a CPU failed to become
onlined. As result acpi_processor_add() will mark such CPU
device as onlined in sysfs and following attempts to
online/offline it using /sys/device/system/cpu/cpuX/online
attribute will fail.
Do not poke into device internals in acpi_processor_add()
and touch "struct device { .offline }" attribute, since
for CPUs onlined at boot it's set by:
topology_init() -> arch_register_cpu() -> register_cpu()
before ACPI device tree is parsed, and for hotplugged
CPUs it's set when userspace onlines CPU via sysfs.

Without this this EEE PC exports a non working WMI interface, with this it
exports a working "good old" eeepc_laptop interface, fixing brightness control
not working as well as rfkill being stuck in a permanent wireless blocked
state.
This is not an ideal way to fix this, but various attempts to fix this
otherwise have failed, see:

With win8 capabiltiy, the machine will boot itself immediately after
shutdown command has executed.
Work around this issue by disabling win8 capcability. This workaround
also makes wireless hotkey work.

If you are using a 64-bit kernel with 32-bit userland, then
scripts/gcc-x86_64-has-stack-protector.sh invokes 32-bit gcc
with -mcmodel=kernel, which produces:
<stdin>:1:0: error: code model 'kernel' not supported in the 32 bit mode
and trips the "broken compiler" test at arch/x86/Makefile:120.
There are several places a fix is possible, but the following seems
cleanest. (But it's minimal; it would also be possible to factor
out a bunch of stuff from the two branches of the if.)

When a ZPODD device is unbound via sysfs, the ACPI notify handler
is not removed. This causes panics as observed in Bug #74601. The
panic only happens when the wake happens from outside the kernel
(i.e. inserting a media or pressing a button). Add a loop to
ata_port_detach which loops through the port's devices and checks
if zpodd is enabled, if so call zpodd_exit.

Most likely the minimums for both should be enough for enabling the
native resolution on the eDP, and we'll end up using the predetermined
optimal link config for the panel.

Even if the panel claims it can support 4 lanes, there's the
possibility that the HW can't, so consider this while selecting the
max lane count.

nouveau fixes.
* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/gm107/gr: bump attrib cb size quite a bit
drm/nouveau: fix another lock unbalance in nouveau_crtc_page_flip
drm/nouveau/bios: fix shadowing from PROM on big-endian systems
drm/nouveau/acpi: allow non-optimus setups to load vbios from acpi
Some more i915 fixes. There's still some DP issues we are looking into,
but wanted to get these moving.
* tag 'topc/core-stuff-2014-05-05' of git://anongit.freedesktop.org/drm-intel:
drm/i915: don't try DP_LINK_BW_5_4 on HSW ULX
drm/i915: Sanitize the enable_ppgtt module option once
drm/i915: Break encoder->crtc link separately in intel_sanitize_crtc()
this is the next pull quested for stashed up radeon fixes for 3.15. As discussed support for Mullins was separated out and will get it's own pull request. Remaining highlights are:
1. Some more patches to better handle PLL limits.
2. Making use of the PFLIP additional to the VBLANK interrupt, otherwise we sometimes miss page flip events.
3. Fix for the UVD command stream parser.
4. Fix for bootup UVD clocks on RV7xx systems.
5. Adding missing error check on dpcd reads.
6. Fixes number of banks calculation on SI.
* 'drm-fixes-3.15' of git://people.freedesktop.org/~deathsimple/linux:
drm/radeon: lower the ref * post PLL maximum
drm/radeon: check that we have a clock before PLL setup
drm/radeon: drm/radeon: add missing radeon_semaphore_free to error path
drm/radeon: Fix num_banks calculation for SI
drm/radeon/dp: check for errors in dpcd reads
drm/radeon: avoid high jitter with small frac divs
drm/radeon: check buffer relocation offset
drm/radeon: use pflip irq on R600+ v2
drm/radeon/uvd: use lower clocks on old UVD to boot v2
Patch 01f8fa4f01 "genirq: Allow forcing cpu affinity of interrupts" added
an irq_force_affinity() function, and 30ccf03b4a "clocksource: Exynos_mct:
Use irq_force_affinity() in cpu bringup" subsequently uses it. However, the
driver can be used with CONFIG_SMP disabled, but the function declaration
is only available for CONFIG_SMP, leading to this build error:
drivers/clocksource/exynos_mct.c:431:3: error: implicit declaration of function 'irq_force_affinity' [-Werror=implicit-function-declaration]
irq_force_affinity(mct_irqs[MCT_L0_IRQ + cpu], cpumask_of(cpu));
This patch introduces a dummy helper function for the non-SMP case
that always returns success, to get rid of the build error.
Since the patches causing the problem are marked for stable backports,
this one should be as well.

autofs: fix lockref lookup
mm: filemap: update find_get_pages_tag() to deal with shadow entries

On 64 bit systems the agp_info struct has a 4 byte hole between
->agp_mode and ->aper_base. We need to clear it to avoid disclosing
stack information to userspace.
