Patch series "Do not touch pages in hot-remove path", v2.
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.

This patch (of 5):
This is a preparation for the following-up patches. The idea of passing
the nid is that it will allow us to get rid of the zone parameter
afterwards.
