Message

Changes in v2:
- Optimize code to resolve compilation warnings;
- Add comments, add debug data, easy to view and modify.

v1:
hibernate_preallocate_memory() function is still quite obscure, can
anyone add a little more description?

It seems that the max_size calculation formula is wrong in the comment
part, correct it;

It is also found that when mem preallocate is not enough, it goes
directly down without checking.

  PM: hibernate: fix spelling mistake for annotation
  PM: hibernate: add check of preallocate mem for image size pages
