[PATCH] ARM: Fix ARM fault handler for get_user_pages() fixes.
The ARM fault handler is optimised to make the fast path, err, fast. The renumbering of the VM_FAULT_* codes broke this because numbers were used instead of the definitions. Fix this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
