Unfortunately this is very incompatible with pending changes in
fs/proc/task_mmu.c. Especially Kirill's "mm, thp: change
pmd_trans_huge_lock() to return taken lock".

Stephen will be away for a couple more weeks so I'll get an mmotm
released and hopefully Thierry and Mark will scoop it up(?).
Alternatively,;a=summary is
up to date.

Please take a look, decide what you think we should do?
