Merge tag 'pm-extra-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki:
"A few more fixes and cleanups in the x86-64 low-level hibernation
code, PM core, cpufreq (Kconfig and intel_pstate), and the operating
points framework.
Specifics:
- Prevent the low-level assembly hibernate code on x86-64 from
referring to __PAGE_OFFSET directly as a symbol which doesn't work
when the kernel identity mapping base is randomized, in which case
__PAGE_OFFSET is a variable (Rafael Wysocki).
- Avoid selecting CPU_FREQ_STAT by default as the statistics are not
required for proper cpufreq operation (Borislav Petkov).
- Add Skylake-X and Broadwell-X IDs to the intel_pstate's list of
processors where out-of-band (OBB) control of P-states is possible
and if that is in use, intel_pstate should not attempt to manage
P-states (Srinivas Pandruvada).
- Drop some unnecessary checks from the wakeup IRQ handling code in
the PM core (Markus Elfring).
- Reduce the number operating performance point (OPP) lookups in one
of the OPP framework's helper functions (Jisheng Zhang)"
* tag 'pm-extra-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
x86/power/64: Do not refer to __PAGE_OFFSET from assembly code
cpufreq: Do not default-yes CPU_FREQ_STAT
cpufreq: intel_pstate: Add more out-of-band IDs
PM / OPP: optimize dev_pm_opp_set_rate() performance a bit
PM-wakeup: Delete unnecessary checks before three function calls
