Note that that branch only removes __get_user/__put_user - and only on x86.
So there's still a lot of valid access_ok() calls left. Some are
around things like raw_copy_to/from_user() etc.
But some are around things that just want to verify that it's a valid
user address for other reasons. On example is in fork.c that just
checks that the stack that is supplied is ok.
But yes, the branch does remove a number of access_ok() calls. Fewer
than you'd maybe think, though.
