Merge tag 'pm-4.13-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
"These fix two issues related to exposing the current CPU frequency to
user space on x86.
Specifics:
- Disable interrupts around reading IA32_APERF and IA32_MPERF in
aperfmperf_snapshot_khz() (introduced recently) to avoid excessive
delays between the reads that may result from interrupt handling
(Doug Smythies).
- Fix the computation of the CPU frequency to be reported through the
pstate_sample tracepoint in intel_pstate (Doug Smythies)"
* tag 'pm-4.13-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpufreq: x86: Disable interrupts during MSRs reading
cpufreq: intel_pstate: report correct CPU frequencies during trace
