[PATCHv2 0/2] arm64: hibernate: a couple of fixes

[Mark Rutland]

Hi,

These patches fix a couple of issues I spotted in the arm64 hibernate code.

Patch 1 addresses potential Break-Before-Make violations, and patch 2 addresses
failure cases where TTBR0 may be left pointing at memory which has been freed.

I've given the kernel a go with these patches applied, and I do not see any
regressions in hibernation functionality.

Thanks,
Mark.

Since v1 [1]:
* s/suspend/hibernate/ in patch 1 title
* Use cpu_set_reserved_ttbr0() to safely handle userspace hibernation testing
* Add patch to safely handle allocation failures
