Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm-4.13-rc6
with top-most commit 8179962b84668d71586cd3efcb70e823f37a5702
Merge branches 'intel_pstate-fix' and 'cpufreq-x86-fix'
on top of commit ef954844c7ace62f773f4f23e28d2d915adc419f
Linux v4.13-rc5
to receive power management fixes for v4.13-rc6.
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 intterrupt handling (Doug Smythies).
- Fix the comutation of the CPU frequency to be reported through the pstate_sample tracepoint in intel_pstate (Doug Smythies).
Thanks!
