Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-4.9-rc3
with top-most commit 8b2ada27dc1045e8191673bf769a1136ce8a0127
Merge branches 'pm-cpufreq-fixes' and 'pm-sleep-fixes'
on top of commit 07d9a380680d1c0eb51ef87ff2eab5c994949e69
Linux 4.9-rc2
to receive power management fixes for v4.9-rc3.
These fix two intel_pstate issues related to the way it works when
the scaling_governor sysfs attribute is set to "performance" and
fix up messages in the system suspend core code.
Specifics:
- Fix a missing KERN_CONT in a system suspend message by converting
the affected code to using pr_info() and pr_cont() instead of the
"raw" printk() (Jon Hunter).
- Make intel_pstate set the CPU P-state from its .set_policy()
callback when the scaling_governor sysfs attribute is set to
"performance" so that it interacts with NOHZ_FULL more
predictably which was the case before 4.7 (Rafael Wysocki).
- Make intel_pstate always request the maximum allowed P-state when
the scaling_governor sysfs attribute is set to "performance" to
prevent it from effectively ingoring that setting is some
situations (Rafael Wysocki).
Thanks!
