parisc: Fix kernel crash with reversed copy_from_user()
commit ef72f3110d8b19f4c098a0bff7ed7d11945e70c6 upstream.
The kernel module testcase (lib/test_user_copy.c) exhibited a kernel
crash on parisc if the parameters for copy_from_user were reversed
("illegal reversed copy_to_user" testcase).
Fix this potential crash by checking the fault handler if the faulting
address is in the exception table.
