Specifics: - 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 yours truly. - 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. Thanks! --------------- Colin Cross (1): freezer: set PF_SUSPEND_TASK flag on tasks that call freeze_processes Lan Tianyu (1): ACPI / battery: Fix parsing _BIX return value Rafael J.
