Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-4.10-rc8
with top-most commit cbf304e420da96992eae50bb6d51035681340ab8
Merge branches 'pm-core-fixes' and 'pm-cpufreq-fixes'
on top of commit d5adbfcd5f7bcc6fa58a41c5c5ada0e5c826ce2c
Linux 4.10-rc7
to receive power management fixes for v4.10-rc8 (if there is one) or
for the final 4.10 (if there's no -rc8).
These add a quirk to intel_pstate to work around a firmware setting
that leads to frequency scaling issues (discovered recently) on some
Intel Kaby Lake processors, fix up the recently added brcmstb-avs
cpufreq driver and avoid false-positive warnings from the runtime PM
framework triggered by recent changes in i915.
Specifics:
- Add an intel_pstate driver quirk to work around a firmware setting
that leads to frequency scaling issues on desktop Intel Kaby Lake
processors in some configurations if the hardware-managed P-states
(HWP) feature is in use (Srinivas Pandruvada).
- Fix up the recently added brcmstb-avs cpufreq driver: fix a bug
related to system suspend and change the sysfs interface to match
the user space expectations (Markus Mayer).
- Modify the runtime PM framework to avoid false-positive warnings
from the might_sleep_if() assertions in it (Rafael Wysocki).
Thanks!
