[PATCH] alpha spinlock code and bogus constraints
"=m" (lock->lock) / "1" (lock->lock) makes gcc4 unhappy; fixed by s/1/m/, same as in case of i386 rwsem.h where such variant had been accepted by both Linus and rth. Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
