This is the first part of page to folio transfer on KSM. Since only
single page could be stored in KSM, we could safely transfer stable tree
pages to folios.
This patchset could reduce ksm.o size to 2487136 from 2547952 bytes on
latest akpm/mm-stable branch with CONFIG_DEBUG_VM enabled.

Alex Shi (tencent) (11):
