parisc: LWS fixes for syscall.S
1) Gate immediately and save a branch. 2) Fix off by one error in checking entry number. 3) Use sr7 instead of sr3 in error return path as sr3 might not contain correct value. 4) Enable locking on UP systems to prevent incorrect operation of the cas_action critical region on page faults. Tested on several systems, including UP c3750 with 2.6.33.2 kernel. Signed-off-by: John David Anglin <dave.anglin@nrc-cnrc.gc.ca> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
