Subject: [GIT PULL] More power management updates for v4.8-rc1

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-extra-4.8-rc1

with top-most commit e2b3b80de5cda284c885721e873f9a6e90f68ef8

 Merge branches 'pm-sleep', 'pm-cpufreq', 'pm-core' and 'pm-opp'

on top of commit 601f887d6105ddd28dc569a1504595bdf8df8a5b

 Merge tag 'pm-urgent-4.8-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive additional power management material for v4.8-rc1.

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).

Thanks!
