Chris Metcalf ab306cae66 arch/tile: use atomic exchange in arch_write_unlock() ... This idiom is used elsewhere when we do an unlock by writing a zero, but I missed it here. Using an atomic operation avoids waiting on the write buffer for the unlocking write to be sent to the home cache. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>		2012-04-02 12:13:49 -04:00
