Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm+acpi-3.17-rc7
to receive ACPI and power management fixes for v3.17-rc7 (or for the final v3.17 if there's no -rc7) with top-most commit 381e63da44301f49be5876d56a5da2434f132dff
Merge branches 'pm-cpufreq' and 'pm-sleep'
on top of commit 0f33be009b89d2268e94194dc4fd01a7851b6d51
Linux 3.17-rc6
These are regression fixes (ACPI hotplug, cpufreq, hibernation, ACPI LPSS driver), fixes for stuff that never worked correctly (ACPI GPIO support in some cases and a wrong sign of an error code in the ACPI core in one place), and one blacklist item for ACPI backlight handling.
Specifics:
- Revert of a recent hibernation core commit that introduced a NULL pointer dereference during resume for at least one user (Rafael J Wysocki).
- Fix for the ACPI LPSS (Low-Power Subsystem) driver to disable asynchronous PM callback execution for LPSS devices during system suspend/resume (introduced in 3.16) which turns out to break ordering expectations on some systems. From Fu Zhonghui.
- cpufreq core fix related to the handling of sysfs nodes during system suspend/resume that has been broken for intel_pstate since 3.15 from Lan Tianyu.
- Restore the generation of "online" uevents for ACPI container devices that was removed in 3.14, but some user space utilities turn out to need them (Rafael J Wysocki).
- The cpufreq core fails to release a lock in an error code path after changes made in 3.14. Fix from Prarit Bhargava.
- ACPICA and ACPI/GPIO fixes to make the handling of ACPI GPIO operation regions (which means AML using GPIOs) work correctly in all cases from Bob Moore and Srinivas Pandruvada.
- Fix for a wrong sign of the ACPI core's create_modalias() return value in case of an error from Mika Westerberg.
- ACPI backlight blacklist entry for ThinkPad X201s from Aaron Lu.
Thanks!
