Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-4.0-rc3
to receive power management and ACPI fixes for v4.0-rc1 with top-most
commit e178e7d6df38dab67f51df4282927c4c7392879f
Merge branches 'pm-domains' and 'pm-cpufreq'
on top of commit 13a7a6ac0a11197edcd0f756a035f472b42cdf8b
Linux 4.0-rc2
These are fixes for recent regressions (ACPI resources management,
suspend-to-idle), stable-candidate fixes (ACPI backlight), fixes
related to the wakeup IRQ management changes made in v3.18, other
fixes (suspend-to-idle, cpufreq ppc driver) and a couple of cleanups
(suspend-to-idle, generic power domains, ACPI backlight).
Specifics:
- Fix ACPI resources management problems introduced by the recent
rework of the code in question (Jiang Liu) and a build issue
introduced by those changes (Joachim Nilsson).
- Fix a recent suspend-to-idle regression on systems where entering
idle states causes local timers to stop, prevent suspend-to-idle
from crashing in restricted configurations (no cpuidle driver,
cpuidle disabled etc.) and clean up the idle loop somewhat while
at it (Rafael J Wysocki).
- Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven).
- Allow the ACPI backlight driver module to be loaded if ACPI is
disabled which helps the i915 driver in those configurations
(stable-candidate) and change the code to help debug unusual use
cases (Chris Wilson).
- Wakeup IRQ management changes in v3.18 caused some drivers on the
at91 platform to trigger a warning from the IRQ core related to
an unexpected combination of interrupt action handler flags.
However, on at91 a timer IRQ is shared with some other devices
(including system wakeup ones) and that leads to the unusual
combination of flags in question. To make it possible to avoid
the warning introduce a new interrupt action handler flag (which
can be used by drivers to indicate the special case to the core)
and rework the problematic at91 drivers to use it and work as
expected during system suspend/resume. From Boris Brezillon,
Rafael J Wysocki and Mark Rutland.
- Clean up the generic power domains subsystem's debugfs interface
(Kevin Hilman).
Thanks!
