Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm+acpi-3.16-rc5
to receive ACPI and power management fixes for v3.16-rc5 with top-most commit 2091044299e9bc3340d845301b13bd92d6c10993
Merge branch 'pm-cpufreq'
on top of commit cd3de83f147601356395b57a8673e9c5ff1e59d1
Linux 3.16-rc4
These are a few regression fixes for ACPI device enumeration and resources management, intel_pstate and cpufreq, a revert of an ACPI commit removing user space interfaces in /proc that we incorrectly thought were not used any more, fixes for some long-standing concurrency issues in the ACPI EC driver, two ACPI battery driver fixes, stable-candidate fixes for intel_pstate, an ACPI-related fix for i915 and two new ACPI video blacklist entries for Win8-oriented BIOSes.
Specifics:
- Missing device ID for ACPI enumeration of PNP devices that we overlooked during the recent rework of that code from Zhang Rui.
- Fix for a problem introduced during the 3.14 cycle in the ACPI device resources management code and causing it to reject all resources of length 0 although some of them are actually valid which affects serial ports detection on a number of systems. From Andy Whitcroft.
- intel_pstate fix for a boot problem on some BayTrail-based systems introduced by a previous fix related to that platform during the 3.13 cycle from Dirk Brandewie.
- Revert of a 3.13 commit that removed the ACPI AC /proc interface which turns out to be still needed by some old utilities (kpowersave from kde 3.5.10 in particular) from Lan Tianyu.
- cpufreq build fix for the davinci ARM platform from Prabhakar Lad (the breakage was introduced during the 3.10 cycle).
- ACPI-related i915 fix preventing firmware on some Thinkpad laptops from setting backlight levels incorrectly during AC plug/unplug. From Aaron Lu.
- Fixes for two nasty race conditions in the ACPI embedded controller driver that may be responsible for a number of past bug reports related to the EC from Lv Zhang and a fix for two memory leaks in error code paths in that driver from Colin Ian King.
- Fixes for a couple of corner-case issues in the intel_pstate driver (all candidates for -stable) from Dirk Brandewie and Vincent Minet.
- Fixes for two corner-case issues in the ACPI battery driver from Josef Gajdusek and Lan Tianyu.
- Two new ACPI video blacklist entries for Acer TravelMate B113 and Dell Inspiron 5737 from Edward Lin and Martin Kepplinger.
Thanks!
