2.6.39-stable review patch. If anyone has any objections, please let us know.
------------------ Content-Length: 894 Lines: 36
From: Samuel Thibault <samuel.thibault@ens-lyon.org>
commit fad4dab5e44e10acf6b0235e469cb8e773b58e31 upstream.
Commit 1292500b replaced
"=m" (*field) : "1" (*field)
with
"=m" (*field) :
with comment "The following patch fixes it by using the '+' operator on the (*field) operand, marking it as read-write to gcc." '+' was actually forgotten. This really puts it.
