- 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).
