I already moved the previous version into mm-stable.  Would prefer not
to have to rebase it.

Please redo this against the mm-stable or mm-unstable branches against
git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm, or against your
own previous version.

The new patch will simply switch to the gfpflag_string() trick, so it will
not be a "fix", so please let's position it as a "cleanup".
