Pull sched.h split-up from Ingo Molnar:
 "The point of these changes is to significantly reduce the
  <linux/sched.h> header footprint, to speed up the kernel build and to
  have a cleaner header structure.

  After these changes the new <linux/sched.h>'s typical preprocessed
  size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K
  lines), which is around 40% faster to build on typical configs.

  Not much changed from the last version (-v2) posted three weeks ago: I
  eliminated quirks, backmerged fixes plus I rebased it to an upstream
  SHA1 from yesterday that includes most changes queued up in -next plus
  all sched.h changes that were pending from Andrew.

  I've re-tested the series both on x86 and on cross-arch defconfigs,
  and did a bisectability test at a number of random points.

  I tried to test as many build configurations as possible, but some
  build breakage is probably still left - but it should be mostly
  limited to architectures that have no cross-compiler binaries
  available on kernel.org, and non-default configurations"

Pull turbostat utility updates from Rafael Wysocki:
 "Power management turbostat utility updates.

  These update turbostat significantly and in particular:

   - default output is now verbose, --debug is no longer required to get
     all counters. As a result, some options have been added to specify
     exactly what output is wanted.

   - added --quiet to skip system configuration output

   - added --list, --show and --hide parameters

   - added --cpu parameter

   - enhanced Baytrail SoC support

   - added Gemini Lake SoC support

   - added sysfs C-state columns

  Also the symbol definitions in arch/x86/include/asm/intel-family.h and
  arch/x86/include/asm/msr-index.h are updated and the intel_idle and
  intel_pstate drivers are modified to use the updated symbols.

 "These fix two bugs introduced by recent power management updates (in

  Specifics:

   - Fix for a cpuidle menu governor problem that started to take an
     unnecessary spinlock after one of the recent updates and that did
     not play well with the RT patch (Rafael Wysocki).

   - Fix for the new intel_pstate operation mode switching feature added
     recently that did not reinitialize P-state limits properly when
     switching operation modes (Rafael Wysocki).

   - Removal of unused global notifiers from the PM QoS framework
     (Viresh Kumar).

   - Generic power domains framework update to make it handle
     asynchronous invocations of PM callbacks in the "noirq" phases of
     system suspend/hibernation correctly (Ulf Hansson).

   - Two hibernation core cleanups (Rafael Wysocki).

   - intel_idle cleanup related to the sysfs interface (Len Brown).

   - Off-by-one bug fix in the OPP (Operating Performance Points)
     framework (Andrzej Hajda).

   - OPP framework's documentation fix (Viresh Kumar).

   - cpufreq qoriq driver cleanup (Tang Yuantian).

   - Fixes for typos in comments in the device runtime PM framework
     (Christophe Jaillet)"

do various trivial cleanups:

 - remove unnecessary structure predeclarations
 - fix various typos
 - update comments where necessary
 - remove pointless comments
 - use consistent types
 - tabulate consistently
 - use a consistent comment style
 - clean up the header section a bit
 - use a consistent style of a single field per line
 - remove line-breaks where they make the code look worse
 - etc ...
