Hmmm...if it's through -mm, doesn't that mean that we can't rely on the
hash because the next time Andrew's tree rebases (using quilt or
whatever it is he does) that the hash will change? It doesn't really
matter too much...we can't take the fix anyway, it should probably be
squashed into the patch that it's fixing, and if you follow Bernard's
advice, you fix the problem by eliminating this function and changing
the sole call site to just call put_user_pages_dirty_lock() directly.
