With your v2 version, you could pass

Correctly setup the temporary mapping for hibernation. Previous
implementation assumed the offset between KVA and PA was aligned on the PGD
level.
With KASLR memory randomization enabled, the offset is randomized on the PUD
level. This change supports unaligned up to PMD.
