Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm-5.2-rc4
with top-most commit a964d23c94e8177c501fc9a37dcf1f0dd2750527
Merge branch 'pm-x86'
on top of commit f2c7c76c5d0a443053e94adb9f0918fa2fb85c3a
Linux 5.2-rc3
to receive power management fixes for 5.2-rc4.
These fix a crash during resume from hibernation introduced during the 4.19 cycle, cause the new Performance and Energy Bias Hint (EPB) code to be built only if CONFIG_PM is set and add a few missing kerneldoc comments.
Specifics:
- Fix a crash that occurs when a kernel with 'nosmt' in the command line is used to resume the system from hibernation (as the "restore" kernel), because memory mapping differences between the restore and image kernels cause SMT siblings to be woken up from idle states and subsequently they try to fetch instructions from incorrect memory locations (Jiri Kosina).
- Cause the new Performance and Energy Bias Hint (EPB) code to be built only if CONFIG_PM is set, because that code is not really necessary otherwise (Rafael Wysocki).
- Add kerneldoc comments to documents some helper functions related to system-wide suspend to avoid possible confusion regarding their purpose (Rafael Wysocki).
Thanks!
