Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-3.19-rc1-2
to receive more ACPI and power management updates for v3.19-rc1 with
top-most commit 2ec1c17cadd0b994732f292d4bc49fc3a05d85a4
Merge branches 'pm-opp', 'pm-cpufreq' and 'pm-tools'
on top of commit 92a578b064d0227a3a7fbbdb9e29dbab7f8d400e
Merge tag 'pm+acpi-3.19-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
These are regrssion fixes (leds-gpio, ACPI backlight driver, operating
performance points library, ACPI device enumeration messages, cpupower
tool), other bug fixes (ACPI EC driver, ACPI device PM), some cleanups
in the operating performance points (OPP) framework, continuation of
CONFIG_PM_RUNTIME elimination, a couple of minor intel_pstate driver
changes, a new MAINTAINERS entry for it and an ACPI fan driver change
needed for better support of thermal management in user space.
Specifics:
- Fix a regression in leds-gpio introduced by a recent commit that
inadvertently changed the name of one of the properties used by
the driver (Fabio Estevam).
- Fix a regression in the ACPI backlight driver introduced by a
recent fix that missed one special case that had to be taken
into account (Aaron Lu).
- Drop the level of some new kernel messages from the ACPI core
introduced by a recent commit to KERN_DEBUG which they should
have used from the start and drop some other unuseful KERN_ERR
messages printed by ACPI (Rafael J Wysocki).
- Revert an incorrect commit modifying the cpupower tool
(Prarit Bhargava).
- Fix two regressions introduced by recent commits in the OPP
library and clean up some existing minor issues in that code
(Viresh Kumar).
- Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout
the tree (or drop it where that can be done) in order to make
it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki,
Ulf Hansson, Ludovic Desroches). There will be one more
"CONFIG_PM_RUNTIME removal" batch after this one, because some
new uses of it have been introduced during the current merge
window, but that should be sufficient to finally get rid of it.
- Make the ACPI EC driver more robust against race conditions
related to GPE handler installation failures (Lv Zheng).
- Prevent the ACPI device PM core code from attempting to
disable GPEs that it has not enabled which confuses ACPICA
and makes it report errors unnecessarily (Rafael J Wysocki).
- Add a "force" command line switch to the intel_pstate driver
to make it possible to override the blacklisting of some
systems in that driver if needed (Ethan Zhao).
- Improve intel_pstate code documentation and add a MAINTAINERS
entry for it (Kristen Carlson Accardi).
- Make the ACPI fan driver create cooling device interfaces
witn names that reflect the IDs of the ACPI device objects
they are associated with, except for "generic" ACPI fans
(PNP ID "PNP0C0B"). That's necessary for user space thermal
management tools to be able to connect the fans with the
parts of the system they are supposed to be cooling properly.
From Srinivas Pandruvada.
Thanks!
