Pull ACPI and power management updates from Rafael Wysocki:
 "The majority of this material spent some time in linux-next, some of
  it even several weeks.  There are a few relatively fresh commits in
  it, but they are mostly fixes and simple cleanups.

  ACPI took the lead this time, both in terms of the number of commits
  and the number of modified lines of code, cpufreq follows and there
  are a few changes in the PM core and in cpuidle too.

  A new feature that already got some LWN.net's attention is the device
  PM QoS extension allowing latency tolerance requirements to be
  propagated from leaf devices to their ancestors with hardware
  interfaces for specifying latency tolerance.  That should help systems
  with hardware-driven power management to avoid going too far with it
  in cases when there are latency tolerance constraints.

  There also are some significant changes in the ACPI core related to
  the way in which hotplug notifications are handled.  They affect PCI
  hotplug (ACPIPHP) and the ACPI dock station code too.  The bottom line
  is that all those notification now go through the root notify handler
  and are propagated to the interested subsystems by means of callbacks
  instead of having to install a notify handler for each device object
  that we can potentially get hotplug notifications for.

  In addition to that ACPICA will now advertise "Windows 2013"
  compatibility for _OSI, because some systems out there don't work
  correctly if that is not done (some of them don't even boot).

  On the system suspend side of things, all of the device suspend and
  resume callbacks, except for ->prepare() and ->complete(), are now
  going to be executed asynchronously as that turns out to speed up
  system suspend and resume on some platforms quite significantly and we
  have a few more optimizations in that area.

  Apart from that, there are some new device IDs and fixes and cleanups
  all over.  In particular, the system suspend and resume handling by
  cpufreq should be improved and the cpuidle menu governor should be a
  bit more robust now.

  Specifics:

   - Device PM QoS support for latency tolerance constraints on systems
     with hardware interfaces allowing such constraints to be specified.
     That is necessary to prevent hardware-driven power management from
     becoming overly aggressive on some systems and to prevent power
     management features leading to excessive latencies from being used
     in some cases.

   - Consolidation of the handling of ACPI hotplug notifications for
     device objects.  This causes all device hotplug notifications to go
     through the root notify handler (that was executed for all of them
     anyway before) that propagates them to individual subsystems, if
     necessary, by executing callbacks provided by those subsystems
     (those callbacks are associated with struct acpi_device objects
     during device enumeration).  As a result, the code in question
     becomes both smaller in size and more straightforward and all of
     those changes should not affect users.

   - ACPICA update, including fixes related to the handling of _PRT in
     cases when it is broken and the addition of "Windows 2013" to the
     list of supported "features" for _OSI (which is necessary to
     support systems that work incorrectly or don't even boot without
     it).  Changes from Bob Moore and Lv Zheng.

   - Consolidation of ACPI _OST handling from Jiang Liu.

   - ACPI battery and AC fixes allowing unusual system configurations to
     be handled by that code from Alexander Mezin.

   - New device IDs for the ACPI LPSS driver from Chiau Ee Chew.

     for the PCI bus type and ACPI PM domain.

     to be used during system suspend and resume more easily from Ulf

Pull irq code updates from Thomas Gleixner:
 "The irq department proudly presents:

   - Another tree wide sweep of irq infrastructure abuse.  Clear winner
     of the trainwreck engineering contest was:
         #include "../../../kernel/irq/settings.h"

   - Tree wide update of irq_set_affinity() callbacks which miss a cpu
     online check when picking a single cpu out of the affinity mask.

   - Tree wide consolidation of interrupt statistics.

   - Updates to the threaded interrupt infrastructure to allow explicit
     wakeup of the interrupt thread and a variant of synchronize_irq()
     which synchronizes only the hard interrupt handler.  Both are
     needed to replace the homebrewn thread handling in the mmc/sdhci
     code.

   - New irq chip callbacks to allow proper support for GPIO based irqs.
     The GPIO based interrupts need to request/release GPIO resources
     from request/free_irq.

   - A few new ARM interrupt chips.  No revolutionary new hardware, just
     differently wreckaged variations of the scheme.

   - Small improvments, cleanups and updates all over the place"

joke.  But no.

Pull percpu changes from Tejun Heo:
 "The percpu allocation is now popular enough for the extremely naive
  range allocator to cause scalability issues.

  The existing allocator linearly scanned the allocation map on both
  alloc and free without making use of hint or anything.  Al
  reimplemented the range allocator so that it can use binary search
  instead of linear scan during free and alloc path uses simple hinting
  to avoid scanning in common cases.  Combined, the new allocator
  resolves the scalability issue percpu allocator was showing during
  container benchmark workload"

Pull s390 compat wrapper rework from Heiko Carstens:
 "S390 compat system call wrapper simplification work.

  The intention of this work is to get rid of all hand written assembly
  compat system call wrappers on s390, which perform proper sign or zero
  extension, or pointer conversion of compat system call parameters.
  Instead all of this should be done with C code eg by using Al's
  COMPAT_SYSCALL_DEFINEx() macro.

  Therefore all common code and s390 specific compat system calls have
  been converted to the COMPAT_SYSCALL_DEFINEx() macro.

  In order to generate correct code all compat system calls may only
  have eg compat_ulong_t parameters, but no unsigned long parameters.
  Those patches which change parameter types from unsigned long to
  compat_ulong_t parameters are separate in this series, but shouldn't
  cause any harm.

  The only compat system calls which intentionally have 64 bit
  parameters (preadv64 and pwritev64) in support of the x86/32 ABI
  haven't been changed, but are now only available if an architecture
  defines __ARCH_WANT_COMPAT_SYS_PREADV64/PWRITEV64.

  System calls which do not have a compat variant but still need proper
  zero extension on s390, like eg "long sys_brk(unsigned long brk)" will
  get a proper wrapper function with the new s390 specific
  COMPAT_SYSCALL_WRAPx() macro:

     COMPAT_SYSCALL_WRAP1(brk, unsigned long, brk);

  which generates the following code (simplified):

     asmlinkage long sys_brk(unsigned long brk);
     asmlinkage long compat_sys_brk(long brk)
     {
         return sys_brk((u32)brk);
     }

  Given that the C file which contains all the COMPAT_SYSCALL_WRAP lines
  includes both linux/syscall.h and linux/compat.h, it will generate
  build errors, if the declaration of sys_brk() doesn't match, or if
  there exists a non-matching compat_sys_brk() declaration.

  In addition this will intentionally result in a link error if
  somewhere else a compat_sys_brk() function exists, which probably
  should have been used instead.  Two more BUILD_BUG_ONs make sure the
  size and type of each compat syscall parameter can be handled
  correctly with the s390 specific macros.

  I converted the compat system calls step by step to verify the
  generated code is correct and matches the previous code.  In fact it
  did not always match, however that was always a bug in the hand
  written asm code.

  In result we get less code, less bugs, and much more sanity checking"

Commit 03bbcb2e (iommu/vt-d: add quirk for broken interrupt
remapping on 55XX chipsets) properly disables irq remapping on the
5500/5520 chipsets that don't correctly perform that feature.

However, when I wrote it, I followed the errata sheet linked in that
commit too closely, and explicitly tied the activation of the quirk to
revision 0x13 of the chip, under the assumption that earlier revisions
were not in the field.  Recently a system was reported to be suffering
from this remap bug and the quirk hadn't triggered, because the
revision id register read at a lower value that 0x13, so the quirk
test failed improperly.  Given this, it seems only prudent to adjust
this quirk so that any revision less than 0x13 has the quirk asserted.

[ tglx: Removed the 0x12 comparison of pci id 3405 as this is covered
    	by the <= 0x13 check already ]
