Pull x86 asm changes from Ingo Molnar:
 "There were lots of changes in this development cycle:

   - over 100 separate cleanups, restructuring changes, speedups and
     fixes in the x86 system call, irq, trap and other entry code, part
     of a heroic effort to deobfuscate a decade old spaghetti asm code
     and its C code dependencies (Denys Vlasenko, Andy Lutomirski)

   - alternatives code fixes and enhancements (Borislav Petkov)

   - simplifications and cleanups to the compat code (Brian Gerst)

   - signal handling fixes and new x86 testcases (Andy Lutomirski)

   - various other fixes and cleanups

  By their nature many of these changes are risky - we tried to test
  them well on many different x86 systems (there are no known
  regressions), and they are split up finely to help bisection - but
  there's still a fair bit of residual risk left so caveat emptor"

56fd85b5dd ASoC: Last minute fix for v4.0
This patch backs out a change that came in during the merge window which
 selects a configuration for GPIO4 on pcm512x CODECs that may not be
 suitable for all systems using the device.  Changes for v4.1 will make
 this properly configurable but for now it's safest to revert to the
 v3.19 behaviour and leave the pin configuration alone.
 
 Sorry for sending this direct at the last minute but due to the GPIO
 misuse it'd be really good to get it in the release and I'd not realised
 it hadn't been sent yet - between some travel, a job change and other
 non-urgent fixes coming in I'd lost track of the urgency.  It's been in
 -next for several weeks now, is isolated to the driver and fairly clear
 to inspection.

14f0413ce3 ASoC: pcm512x: Remove hardcoding of pll-lock to GPIO4
Currently GPIO4 is hardcoded to output the pll-lock signal.
Unfortunately this is after the pll-out GPIO is configured which
is selectable in the device tree. Therefore it is not possible to
use GPIO4 for pll-out. Therefore this patch removes the
configuration of GPIO4.

This reverts commit ecc19d1786.

It added a new warning to try to encourage driver writers to set the
device capabities properly, but drivers haven't been updated and in the
meantime it just generaters a scary message that users cannot actually
do anything about.

Warnings like these are appropriate if you actually expect to fix the
code that causes them.  They are not appropriate for releases.

ac2111753c blk-mq: initialize 'struct request' and associated data to zero
Jan Engelhardt reports a strange oops with an invalid ->sense_buffer
pointer in scsi_init_cmd_errh() with the blk-mq code.

The sense_buffer pointer should have been initialized by the call to
scsi_init_request() from blk_mq_init_rq_map(), but there seems to be
some non-repeatable memory corruptor.

This patch makes sure we initialize the whole struct request allocation
(and the associated 'struct scsi_cmnd' for the SCSI case) to zero, by
using __GFP_ZERO in the allocation.  The old code initialized a couple
of individual fields, leaving the rest undefined (although many of them
are then initialized in later phases, like blk_mq_rq_ctx_init() etc.

It's not entirely clear why this matters, but it's the rigth thing to do
regardless, and with 4.0 imminent this is the defensive "let's just make
sure everything is initialized properly" patch.

This fixes a oops due to a double list add when adding a reject PDU for
iscsit_allocate_iovecs allocation failures. The cmd has already been
added to the conn_cmd_list in iscsit_setup_scsi_cmd, so this has us call
iscsit_reject_cmd.

Note that for ERL0 the reject PDU is not actually sent, so this patch
is not completely tested. Just verified we do not oops. The problem is the
add reject functions return -1 which is returned all the way up to
iscsi_target_rx_thread which for ERL0 will drop the connection.

ca3f087472 KVM: use slowpath for cross page cached accesses
kvm_write_guest_cached() does not mark all written pages as dirty and
code comments in kvm_gfn_to_hva_cache_init() talk about NULL memslot
with cross page accesses.  Fix all the easy way.

The check is '<= 1' to have the same result for 'len = 0' cache anywhere
in the page.  (nr_pages_needed is 0 on page boundary.)

Fixes: 8f964525a1 ("KVM: Allow cross page reads and writes from cached translations.")

379b97e280 x86/apic/uv: Update the UV APIC driver check
Fix a bug in the OEM check function that determines if the
system is a UV system and the BIOS is compatible with the
kernel's UV apic driver.  This prevents some possibly obscure
panics and guards the system against being started on SGI
hardware that does not have the required kernel support.

47d68979cc md/raid0: fix bug with chunksize not a power of 2.
Since commit 20d0189b10
in v3.14-rc1 RAID0 has performed incorrect calculations
when the chunksize is not a power of 2.

This happens because "sector_div()" modifies its first argument, but
this wasn't taken into account in the patch.

So restore that first arg before re-using the variable.

4a89c3088f nios2: fix cache coherency issue when debug with gdb
Remove the end address checking for flushda function. We need to flush
each address line for flushda instruction, from start to end address.
This is because flushda instruction only flush the cache if tag and line
fields are matched.

Change to use ldwio instruction (bypass cache) to load the instruction
that causing trap. Our interest is the actual instruction that executed
by the processor, this should be uncached.
Note, EA address might be an userspace cached address.

e5e02de066 Power management and ACPI fixes for v4.0-rc8
- Revert a 3.17 hibernate commit that was supposed to fix an issue
    related to e820 reserved regions, but broke resume from hibernation
    on Lenovo x230 (Rafael J Wysocki).
 
  - Prevent the ACPI cpuidle driver from overwriting the name and
    description of the C0 state set by the core when the list of
    C-states changes (Thomas Schlichter).
 
  - Remove the no longer needed state_count field from struct cpuidle_device
    which prevents the list of C-states shown by the sysfs interface from
    becoming incorrect when the current number of them is different from
    the number of C-states on boot (Bartlomiej Zolnierkiewicz).
 
  - The cpufreq core updates the policy object of the only online CPU
    during system resume to make it reflect the current hardware state,
    but it always assumes that CPU to be CPU0 which need not be the
    case, so fix the code to avoid that assumption (Viresh Kumar).

64b4e2526d ocfs2: _really_ sync the right range
"ocfs2 syncs the wrong range" had been broken; prior to it the
code was doing the wrong thing in case of O_APPEND, all right,
but _after_ it we were syncing the wrong range in 100% cases.
*ppos, aka iocb->ki_pos is incremented prior to that point,
so we are always doing sync on the area _after_ the one we'd
written to.
