Merge tag 'pm+acpi-3.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management fixes from Rafael Wysocki:
- Revert two cpuidle commits added during the 3.8 development cycle
that turn out to have introduced a significant performance regression
as requested by Jeremy Eder.
- The recent patches that made the freezer less heavy-weight introduced
a regression causing user-space-driven hibernation using the ioctl()
interface to block indefinitely when the hibernate process executes
try_to_freeze(). Fix from Colin Cross addresses this by adding a
process flag to mark the hibernate/suspend process to inform the
freezer that that process should be ignored.
- One of the recent cpufreq reverts uncovered a problem in the core
causing the cpufreq driver module refcount to become negative after a
system suspend-resume cycle. Fix from Rafael J Wysocki.
- The evaluation of the ACPI battery _BIX method has never worked
correctly, because the commit that added support for it forgot to
take the "Revision" field in the return package into account. As a
result, the reading of battery info doesn't work at all on some
systems, which is addressed by a fix from Lan Tianyu.
