| |
Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm-4.7-rc7
to receive power management fixes for v4.7-rc7 with top-most commit 7fe39a21557b251e101671f2c3f79558a756afef
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!
