2.6.33-longterm review patch. If anyone has any objections, please let us know.


From: Samuel Thibault <samuel.thibault@xxxxxxxxxxxx>

commit fad4dab5e44e10acf6b0235e469cb8e773b58e31 upstream.

Commit 1292500b replaced

"=m" (*field) : "1" (*field)


"=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.
