Fix sparc64 niagara optimized RAID xor asm
patch d060db63 in mainline. [SPARC64]: Fix register usage in xor_raid_4(). Some typos led to using %i6/%i7 instead of %l6/%l7 in loads which is really really bad because those are the frame pointer and return PC. Based upon a raid5 crash report by Bertrand Joel.
