Hi Linus,

Please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-3.19-rc3

to receive power management and ACPI material for v3.19-rc3 with
top-most commit 651c3293bf333c774f3d4c9876a6552d0ac2f5b9

Merge branch 'acpi-video'

on top of commit b7392d2247cfe6771f95d256374f1a8e6a6f48d6

Linux 3.19-rc2

These are fixes (operating performance points library, cpufreq-dt
driver, cpufreq core, ACPI backlight, cpupower tool), cleanups
(cpuidle), new processor IDs for the RAPL (Running Average Power
Limit) power capping driver, and a modification of the generic
power domains framework allowing modular drivers to call one of
its helper functions.

Specifics:

- Fix for a potential NULL pointer dereference in the cpufreq
core due to an initialization race condition (Ethan Zhao).

- Fixes for abuse of the OPP (Operating Performance Points) API
related to RCU and other minor issues in the OPP library and
the cpufreq-dt driver (Dmitry Torokhov).

- cpuidle governors cleanup making them measure idle duration in
a better way without using the CPUIDLE_FLAG_TIME_INVALID flag
which allows that flag to be dropped from the ACPI cpuidle driver
and from the core too (Len Brown).

- New ACPI backlight blacklist entries for Samsung machines
without a working native backlight interface that need to
use the ACPI backlight instead (Aaron Lu).

- New CPU IDs of future Intel Xeon CPUs for the Intel RAPL power
capping driver (Jacob Pan).

- Generic power domains framework modification to export the
of_genpd_get_from_provider() function to modular drivers that
will allow future driver modifications to be based on the mainline
(Amit Daniel Kachhap).

- Two fixes for the cpupower tool (Michal Privoznik, Prarit Bhargava).

Thanks and Happy New Year!
