Merge branches 'pm-cpuidle-fixes' and 'pm-sleep-fixes'
on top of commit a99cde438de0c4c0cecc1d1af1a55a75b10bfdef
Linux 4.7-rc6
One fix for a recent cpuidle core change that, against all odds,
introduced a functional regression on Power systems and the fix
for the crash during resume from hibernation on x86-64 that has
been in the works for the last few weeks (it actually was ready
last week, but I wanted to allow the reporters to test if for some
more time).
Specifics:
- Fix a recent performance regression on Power systems (powernv
and pseries) introduced by a core cpuidle commit that decreased
the precision of the last_residency conversion from nano- to
microseconds, which should not matter in theory, but turned out
to play not-so-well with the special "snooze" idle state on Power
(Shreyas B Prabhu).
- Fix a crash during resume from hibernation on x86-64 caused by
possible corruption of the kernel text part of page tables in the
last phase of image restoration exposed by a security-related
change during the 4.3 development cycle (Rafael Wysocki).
Thanks!
