[PATCH] ARM: Move copy/clear user_page locking into implementation Move the locking for copy_user_page() and clear_user_page() into the implementations which require locking. For simple memcpy/ memset based implementations, the locking is extra overhead which is not necessary, and prevents preemption occuring. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
