Merge tag 'pm+acpi-3.15-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI and power management fixes and updates from Rafael Wysocki:
"This is PM and ACPI material that has emerged over the last two weeks
and one fix for a CPU hotplug regression introduced by the recent CPU
hotplug notifiers registration series.
Included are intel_idle and turbostat updates from Len Brown (these
have been in linux-next for quite some time), a new cpufreq driver for
powernv (that might spend some more time in linux-next, but BenH was
asking me so nicely to push it for 3.15 that I couldn't resist), some
cpufreq fixes and cleanups (including fixes for some silly breakage in
a couple of cpufreq drivers introduced during the 3.14 cycle),
assorted ACPI cleanups, wakeup framework documentation fixes, a new
sysfs attribute for cpuidle and a new command line argument for power
domains diagnostics.
Specifics:
- Fix for a recently introduced CPU hotplug regression in ARM KVM
from Ming Lei.
- Fixes for breakage in the at32ap, loongson2_cpufreq, and unicore32
cpufreq drivers introduced during the 3.14 cycle (-stable material)
from Chen Gang and Viresh Kumar.
- New powernv cpufreq driver from Vaidyanathan Srinivasan, with bits
from Gautham R Shenoy and Srivatsa S Bhat.
- Exynos cpufreq driver fix preventing it from being included into
multiplatform builds that aren't supported by it from Sachin Kamat.
- cpufreq cleanups related to the usage of the driver_data field in
struct cpufreq_frequency_table from Viresh Kumar.
- cpufreq ppc driver cleanup from Sachin Kamat.
- Intel BayTrail support for intel_idle and ACPI idle from Len Brown.
- Intel CPU model 54 (Atom N2000 series) support for intel_idle from
Jan Kiszka.
- intel_idle fix for Intel Ivy Town residency targets from Len Brown.
- turbostat updates (Intel Broadwell support and output cleanups)
from Len Brown.
- New cpuidle sysfs attribute for exporting C-states' target
residency information to user space from Daniel Lezcano.
- New kernel command line argument to prevent power domains enabled
by the bootloader from being turned off even if they are not in use
(for diagnostics purposes) from Tushar Behera.
- Fixes for wakeup sysfs attributes documentation from Geert
Uytterhoeven.
- New ACPI video blacklist entry for ThinkPad Helix from Stephen
Chandler Paul.
- Assorted ACPI cleanups and a Kconfig help update from Jonghwan
Choi, Zhihui Zhang, Hanjun Guo"
