SMAP is disabled if CPU is in non-paging mode in hardware.
However KVM always uses paging mode to emulate guest non-paging
mode with TDP. To emulate this behavior, SMAP needs to be
manually disabled when guest switches to non-paging mode.

The RTC tracking code tracks the cardinality of rtc_status.dest_map
into rtc_status.pending_eoi.  It has some WARN_ONs that trigger if
pending_eoi ever becomes negative; however, these do not do anything
to recover, and it bad things will happen soon after they trigger.

When the next RTC interrupt is triggered, rtc_check_coalesced() will
return false, but ioapic_service will find pending_eoi != 0 and
do a BUG_ON.  To avoid this, should pending_eoi ever be nonzero,
call kvm_rtc_eoi_tracking_restore_all to recompute a correct
dest_map and pending_eoi.

QE reported that they got the BUG_ON in ioapic_service to trigger.
I cannot reproduce it, but there are two reasons why this could happen.

The less likely but also easiest one, is when kvm_irq_delivery_to_apic
does not deliver to any APIC and returns -1.

Because irqe.shorthand == 0, the kvm_for_each_vcpu loop in that
function is never reached.  However, you can target the similar loop in
kvm_irq_delivery_to_apic_fast; just program a zero logical destination
address into the IOAPIC, or an out-of-range physical destination address.

Pull kvm updates from Paolo Bonzini:
 "PPC and ARM do not have much going on this time.  Most of the cool
  stuff, instead, is in s390 and (after a few releases) x86.

  ARM has some caching fixes and PPC has transactional memory support in
  guests.  MIPS has some fixes, with more probably coming in 3.16 as
  QEMU will soon get support for MIPS KVM.

  For x86 there are optimizations for debug registers, which trigger on
  some Windows games, and other important fixes for Windows guests.  We
  now expose to the guest Broadwell instruction set extensions and also
  Intel MPX.  There's also a fix/workaround for OS X guests, nested
  virtualization features (preemption timer), and a couple kvmclock
  refinements.

  For s390, the main news is asynchronous page faults, together with
  improvements to IRQs (floating irqs and adapter irqs) that speed up
  virtio devices"

     introduce code to automatically serialize the execution of methods
     creating any named objects which really cannot be executed in
     parallel with each other anyway (previously ACPICA attempted to
     address that by aborting methods upon conflict detection, but that
     wasn't reliable enough and led to other issues).  From Bob Moore
     and Lv Zheng.

   - intel_pstate fix to use del_timer_sync() instead of del_timer() in
     the exit path before freeing the timer structure from Dirk
     Brandewie (original patch from Thomas Gleixner).

   - cpufreq fix related to system resume from Viresh Kumar.

   - Serialization of frequency transitions in cpufreq that involve
     PRECHANGE and POSTCHANGE notifications to avoid ordering issues
     resulting from race conditions.  From Srivatsa S Bhat and Viresh
     Kumar.

   - Revert of an ACPI processor driver change that was based on a
     specific interpretation of the ACPI spec which may not be correct
     (the relevant part of the spec appears to be incomplete).  From
     Hanjun Guo.

  This is the main pull request with most of the work for this merge

  There is some additional cpuidle driver work, however I haven't
  included it in this tree as it depends on some work in tip/timer-core
  which Thomas accidentally forgot to put in a topic branch.  Since I
  didn't want to carry all of that tip timer stuff in powerpc -next, I
  setup a separate branch on top of Thomas tree with just that cpuidle
  driver in it, and Stephen has been carrying that in next separately
  for a while now.  I'll send a separate pull request for it.

  Additionally, two new pieces in this tree add users for a sysfs API
  that Tejun and Greg have been deprecating in drivers-core-next.
  Thankfully Greg reverted the patch that removes the old API so this
  merge can happen cleanly, but once merged, I will send a patch
  adjusting our new code to the new API so that Greg can send you the
  removal patch.

  Now as for the content of this branch, we have a lot of perf work for
  power8 new counters including support for our new "nest" counters
  (also called 24x7) under pHyp (not natively yet).

  We have new functionality when running under the OPAL firmware
  (non-virtualized or KVM host), such as access to the firmware error
  logs and service processor dumps, system parameters and sensors, along
  with a hwmon driver for the latter.

  There's also a bunch of bug fixes accross the board, some LE fixes,
  and a nice set of selftests for validating our various types of copy
  loops.

  On the Freescale side, we see mostly new chip/board revisions, some
  clock updates, better support for machine checks and debug exceptions,

Pull x86 vdso changes from Peter Anvin:
 "This is the revamp of the 32-bit vdso and the associated cleanups.

  This adds timekeeping support to the 32-bit vdso that we already have
  in the 64-bit vdso.  Although 32-bit x86 is legacy, it is likely to
  remain in the embedded space for a very long time to come.

  This removes the traditional COMPAT_VDSO support; the configuration
  variable is reused for simply removing the 32-bit vdso, which will
  produce correct results but obviously suffer a performance penalty.
  Only one beta version of glibc was affected, but that version was
  unfortunately included in one OpenSUSE release.

  This is not the end of the vdso cleanups.  Stefani and Andy have
  agreed to continue work for the next kernel cycle; in fact Andy has
  already produced another set of cleanups that came too late for this
  cycle.

  An incidental, but arguably important, change is that this ensures
  that unused space in the VVAR page is properly zeroed.  It wasn't
  before, and would contain whatever garbage was left in memory by BIOS
  or the bootloader.  Since the VVAR page is accessible to user space
  this had the potential of information leaks"

 "x86: Clean up dumpstack_64.c code" changed

The irq_stack_end variable needed to be cleared after its first
use. By setting irq_stack to the per cpu irq_stack and passing
that to analyze_stack(), and then clearing it after it is processed,
we can get back the original behavior.

Commit 2223f6f6

 "x86: Clean up dumpstack_64.c code" moved the used
variable to a local within the loop, but the in_exception_stack()
depended on being non-volatile with the ability to change it.

By always re-initializing the "used" variable to zero, it would cause
the in_exception_stack() to return the same thing each time, and
cause the dump_stack loop to go into an infinite loop.

Pull sound updates from Takashi Iwai:
 "There have been lots of changes in ALSA core, HD-audio and ASoC, also
  most of PCI drivers touched by conversions of printks.  All these
  resulted in a high volume and wide ranged patch sets in this release.
  Many changes are fairly trivial, but also lots of nice cleanups and
  refactors.  There are a few new drivers, most notably, the Intel
  Haswell and Baytrail ASoC driver.

  Core changes:
   - A bit modernization; embed the device struct into snd_card struct,
     so that it may be referred from the beginning.  A new
     snd_card_new() function is introduced for that, and all drivers
     have been converted.

   - Simplification in the device management code in ALSA core; now
     managed by a simple priority list instead

   - Converted many kernel messages to use the standard dev_err() & co;
     this would be the pretty visible difference, especially for
     HD-audio.

  HD-audio:
   - Conexant codecs use the auto-parser as default now; the old static
     code still remains in case of regressions.  Some old quirks have
     been rewritten with the fixups for auto-parser.

   - C-Media codecs also use the auto-parser as default now, too.

   - A device struct is assigned to each HD-audio codec, and the
     formerly hwdep attributes are accessible over the codec sysfs, too.
     hwdep attributes still remain for compatibility.

   - Split the PCI-specific stuff for HD-audio controller into a
     separate module, ane make a helper module for the generic
     controller driver.  This is a preliminary change for supporting
     Tegra HDMI controller in near future, which slipped from 3.15
     merge.

   - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
     fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
     laptop headset quirks

   - Make the HD-audio codec response a bit more robust

   - A few improvements on Realtek ALC282 / 283 about the pop noises

   - A couple of Intel HDMI fixes

  ASoC:
   - Lots of cleanups for enumerations; refactored lots of error prone
     original codes to use more modern APIs

   - Elimination of the ASoC level wrappers for I2C and SPI moving us
     closer to converting to regmap completely and avoiding some
     randconfig hassle

   - Provide both manually and transparently locked DAPM APIs rather
     than a mix of the two fixing some concurrency issues

   - Start converting CODEC drivers to use separate bus interface
     drivers rather than having them all in one file helping avoid
     dependency issues

   - DPCM support for Intel Haswell and Bay Trail platforms, lots of
     fixes

   - Lots of work on improvements for simple-card, DaVinci and the
     Renesas rcar drivers.

   - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
     the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8

   - Fixes for the simple-card DAI format DT mess

   - DT support for a couple more devices.

   - Use of the tdm_slot mapping in a few drivers

  Others:
   - Support of reset_resume callback for improved S4 in USB-audio
     driver; the device with boot quirks have been little tested, which
     we need to watch out in this development cycle

   - Add PM support for ICE1712 driver (finally!); it's still pretty
     partial support, only for M-Audio devices"

Pull spi Updates from Mark Brown:
 "A busy release for both cleanups and new drivers this time along with
  further factoring out of replicated code into the core:

   - Provide support in the core for DMA mapping transfers - essentially
     all drivers weren't implementing this properly, now there's no
     excuse.
   - Dual and quad mode support for spidev.
   - Fix handling of cs_change in the generic implementation.
   - Remove the S3C_DMA code from the s3c64xx driver now that all the
     platforms using it have been converted to dmaengine.
   - Lots of improvements to the Renesas SPI controllers.
   - Drivers for Allwinner A10 and A31, Qualcomm QUP and Xylinx xtfpga.
   - Removal of the bitrotted ti-ssp driver"

Pull regulator updates from Mark Brown:
 "This release has lots and lots of small cleanups and fixes in the
  regulator subsystem, mainly cleaning up some bad patterns that got
  duplicated in DT code, but otherwise very little of note outside of
  the scope of the relevant drivers:

   - Support for configuration of the initial state for gpio regulators
     with multi-voltage support.
   - Support for calling regulator_set_voltage() on fixed regulators.
   - New drivers for Broadcom BCM590xx, Freescale pfuze200, Samsung
     S2MPA01 & S2MPS11/4, some PWM controlled regulators found on some
     ST boards and TI TPS65218"

Pull regmap updates from Mark Brown:
 "Quite a busy release for regmap this time around, the standout changes
  are:

   - A real implementation of regmap_multi_write() and a bypassed
     version of it for use by drivers doing patch-like things with more
     open coding for surrounding startup sequences.
   - Support fast_io on bulk operations.
   - Support split device binding and map initialisation for use by
     devices required in early init (mainly system controllers).
   - Fixes for some operations on maps with strides set.
   - Export the value parsing operations to help generic code built on
     top of the API.
   - Support for MMIO regmaps with non-32 bit register sizes.

  plus a few smaller fixes"
