[GIT PULL] ACPI and power management fixes for v3.12-rc7

[Rafael J. Wysocki]

Hi Linus,

Please pull from the git repository at

  git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm+acpi-3.12-rc7

to receive ACPI and power management fixes for v3.12-rc7 with
top-most commit 75c0758137c7ac647927b4b12bb5cfca96a0e4e6

  acpi-cpufreq: Fail initialization if driver cannot be registered

on top of commit 31d141e3a666269a3b6fcccddb0351caf7454240

  Linux 3.12-rc6

These fix two bugs in the intel_pstate driver, a hibernate bug leading
to nasty resume failures sometimes and acpi-cpufreq initialization bug
that causes problems to happen during module unload when intel_pstate
is in use.

Specifics:

 - Fix for rounding errors in intel_pstate causing CPU utilization to
   be underestimated from Brennan Shacklett.

 - intel_pstate fix to always use the correct max pstate value when
   computing the min pstate from Dirk Brandewie.

 - Hibernation fix for deadlocking resume in cases when the probing
   of the device containing the image is deferred from Russ Dill.

 - acpi-cpufreq fix to prevent the module from staying in memory
   when the driver cannot be registered and then attempting to
   unregister things that have never been registered on exit.

Thanks!
