[GIT PULL] More ACPI and power management updates for v3.16-rc1

[Rafael J. Wysocki]

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm+acpi-3.16-rc1-2

to receive additional ACPI and power management updates for v3.16-rc1
with top-most commit d715a226b0b3dae48865d05e8c36175a8f75a809

 Merge branch 'pm-sleep'

on top of commit 4dc4226f994db264c844a5fcf556935c66f963a5

 Merge tag 'pm+acpi-3.16-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm into
next

These are fixups on top of the previous PM+ACPI pull request,
regression fixes (ACPI hotplug, cpufreq ppc-corenet), other bug
fixes (ACPI reset, cpufreq), new PM trace points for system suspend
profiling and a copyright notice update.

Specifics:

 - I didn't remember correctly that the Hans de Goede's ACPI video
   patches actually didn't flip the video.use_native_backlight
   default, although we had discussed that and decided to do that.
   Since I said we would do that in the previous PM+ACPI pull
   request, make that change for real now.

 - ACPI bus check notifications for PCI host bridges don't cause
   the bus below the host bridge to be checked for changes as they
   should because of a mistake in the ACPI-based PCI hotplug (ACPIPHP)
   subsystem that forgets to add hotplug contexts to PCI host bridge
   ACPI device objects.  Create hotplug contexts for PCI host bridges
   too as appropriate.

 - Revert recent cpufreq commit related to the big.LITTLE cpufreq
   driver that breaks arm64 builds.

 - Fix for a regression in the ppc-corenet cpufreq driver introduced
   during the 3.15 cycle and causing the driver to use the remainder
   from do_div instead of the quotient.  From Ed Swarthout.

 - Resets triggered by panic activate a BUG_ON() in vmalloc.c on
   systems where the ACPI reset register is located in memory address
   space.  Fix from Randy Wright.

 - Fix for a problem with cpufreq governors that decisions made by
   them may be suboptimal due to the fact that deferrable timers are
   used by them for CPU load sampling.  From Srivatsa S Bhat.

 - Fix for a problem with the Tegra cpufreq driver where the CPU
   frequency is temporarily switched to a "stable" level that
   is different from both the initial and target frequencies
   during transitions which causes udelay() to expire earlier than
   it should sometimes.  From Viresh Kumar.

 - New trace points and rework of some existing trace points for
   system suspend/resume profiling from Todd Brandt.

 - Assorted cpufreq fixes and cleanups from Stratos Karafotis and
   Viresh Kumar.

 - Copyright notice update for suspend-and-cpuhotplug.txt from
   Srivatsa S Bhat.

Thanks!
