I forgot to add it. Here is the changelog:

Patch 1: updated according to kosaki's suggestion

Patch 2: new patch, and update mce_bad_pages when removing memory.

Patch 4: new patch, and fix a NR_FREE_PAGES mismatch, and this bug
cause oom in my test.

Patch 5: new patch, and fix a new bug. When repeating to online/offline
pages, the free pages will continue to decrease.
