Subject: [GIT PULL] Power management fixes for v3.13-rc3

Hi Linus,

Please pull from the git repository at

  git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm-3.13-rc3

to receive power management fixes for v3.13-rc3 with
top-most commit 8e7030097e9f3ea8031e8cc4230e357cb556f8f9

  Merge branches 'pm-epoll', 'pnp' and 'powercap'

on top of commit dc1ccc48159d63eca5089e507c82c7d22ef60839

  Linux 3.13-rc2

These fix two regressions introduced in 3.12 (in cpufreq and PNP core),
fix up the new power capping framework and recent changes in intel_idle
and cpufreq, and fix a couple of older bugs.

Specifics:

 - cpufreq regression fix from Bjørn Mork restoring the pre-3.12
   behavior of the framework during system suspend/hibernation to
   avoid garbage sysfs files from being left behind in case of a
   suspend error.

 - PNP regression fix to restore the correct states of devices after
   resume from hibernation broken in 3.12.  From Dmitry Torokhov.

 - cpuidle fix to prevent cpuidle device unregistration from crashing 
   due to a NULL pointer dereference if cpuidle has been disabled
   from the kernel command line.  From Konrad Rzeszutek Wilk.

 - intel_idle fix for the C6 state definition on Intel Avoton/Rangeley
   processors from Arne Bockholdt.

 - Power capping framework fix to make the energy_uj sysfs attribute
   work in accordance with the documentation.  From Srinivas Pandruvada.

 - epoll fix to make it ignore the EPOLLWAKEUP flag if the kernel has
   been compiled with CONFIG_PM_SLEEP unset (in which case that flag
   should not have any effect).  From Amit Pundir.

 - cpufreq fix to prevent governor sysfs files from being lost over
   system suspend/resume in some (arguably unusual) situations.  From
   Viresh Kumar.

Thanks!
