Pull mm gup cleanup from Ingo Molnar: "This removes the ugly get-user-pages API hack, now that all upstream code has been migrated to it" ("ugly" is putting it mildly. But it worked.. - Linus) * 'mm-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: mm/gup: Remove the macro overload API migration helpers from the get_user*() APIs
