3.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: "H. Peter Anvin" <[email protected]> commit 8c91c5325e107ec17e40a59a47c6517387d64eb7 upstream. Similar to: 2ca052a x86: Use correct byte-sized register constraint in __xchg_op() ... the __add() macro also needs to use a "q" constraint in the byte-sized case, lest we try to generate an illegal register.
