From: Oscar Salvador <osalvador@xxxxxxxx>
This patchset is based on Dan's HMM/devm refactorization [1].
----
This patchset aims for two things:
1) A better definition about offline and hot-remove stage
2) Solving bugs where we can access non-initialized pages
during hot-remove operations [2] [3].
This is achieved by moving all page/zone handling to the offline
stage, so we do not need to access pages when hot-removing memory.
