Merge tag 'pm+acpi-4.5-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull power management and ACPI fixes from Rafael Wysocki:
 "Two build fixes for cpufreq drivers (including one for breakage
  introduced recently) and a fix for a graph tracer crash when used over
  suspend-to-RAM on x86.

  Specifics:

   - Prevent the graph tracer from crashing when used over suspend-to-
     RAM on x86 by pausing it before invoking do_suspend_lowlevel() and
     un-pausing it when that function has returned (Todd Brandt).

   - Fix build issues in the qoriq and mediatek cpufreq drivers related
     to broken dependencies on THERMAL (Arnd Bergmann)"
