Kirill A. Shutemov bf929152e9 mm, thp: change pmd_trans_huge_lock() to return taken lock
With split ptlock it's important to know which lock
pmd_trans_huge_lock() took.  This patch adds one more parameter to the
function to return the lock.

In most places migration to new api is trivial.  Exception is
move_huge_pmd(): we need to take two locks if pmd tables are different.
