Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-3.15-rc1-3
to receive additional ACPI and power management updates and a CPU hotplug
regression fix for v3.15-rc1 with top-most commit 19ce7f3f31103d7a5b0e93
Merge branch 'acpi-config'
on top of commit 467a9e1633043810259a7f5368fbcc1e84746137
Merge tag 'cpu-hotplug-3.15-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
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.
Thanks!
