Subject: [GIT PULL] More ACPI and power management updates for v3.16-rc1
Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-3.16-rc1-2
to receive additional ACPI and power management updates for v3.16-rc1
with top-most commit d715a226b0b3dae48865d05e8c36175a8f75a809
Merge branch 'pm-sleep'
on top of commit 4dc4226f994db264c844a5fcf556935c66f963a5
Merge tag 'pm+acpi-3.16-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm into
next
These are fixups on top of the previous PM+ACPI pull request,
regression fixes (ACPI hotplug, cpufreq ppc-corenet), other bug
fixes (ACPI reset, cpufreq), new PM trace points for system suspend
profiling and a copyright notice update.
Specifics:
- I didn't remember correctly that the Hans de Goede's ACPI video
patches actually didn't flip the video.use_native_backlight
default, although we had discussed that and decided to do that.
Since I said we would do that in the previous PM+ACPI pull
request, make that change for real now.
- ACPI bus check notifications for PCI host bridges don't cause
the bus below the host bridge to be checked for changes as they
should because of a mistake in the ACPI-based PCI hotplug (ACPIPHP)
subsystem that forgets to add hotplug contexts to PCI host bridge
ACPI device objects. Create hotplug contexts for PCI host bridges
too as appropriate.
- Revert recent cpufreq commit related to the big.LITTLE cpufreq
driver that breaks arm64 builds.
- Fix for a regression in the ppc-corenet cpufreq driver introduced
during the 3.15 cycle and causing the driver to use the remainder
from do_div instead of the quotient. From Ed Swarthout.
- Resets triggered by panic activate a BUG_ON() in vmalloc.c on
systems where the ACPI reset register is located in memory address
space. Fix from Randy Wright.
- Fix for a problem with cpufreq governors that decisions made by
them may be suboptimal due to the fact that deferrable timers are
used by them for CPU load sampling. From Srivatsa S Bhat.
- Fix for a problem with the Tegra cpufreq driver where the CPU
frequency is temporarily switched to a "stable" level that
is different from both the initial and target frequencies
during transitions which causes udelay() to expire earlier than
it should sometimes. From Viresh Kumar.
- New trace points and rework of some existing trace points for
system suspend/resume profiling from Todd Brandt.
- Assorted cpufreq fixes and cleanups from Stratos Karafotis and
Viresh Kumar.
- Copyright notice update for suspend-and-cpuhotplug.txt from
Srivatsa S Bhat.
Thanks!
