2005-07-28[ARM SMP] Fix another ARMv6 bitop problemRussell King
We sometimes forgot to check whether the exclusive store succeeded. Ensure that we always check. Also ensure that we always use the out of line versions, since the inline versions are not SMP safe. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
