Christophe Leroy de1cd07906 powerpc/32s: Use SPRN_SPRG_SCRATCH2 in DSI prolog ... Use SPRN_SPRG_SCRATCH2 as an alternative scratch register in the early part of DSI prolog in order to avoid clobbering SPRN_SPRG_SCRATCH0/1 used by other prologs. The 603 doesn't like a jump from DataLoadTLBMiss to the 10 nops that are now in the beginning of DSI exception as a result of the feature section. To workaround this, add a jump as alternative. It also avoids fetching 10 nops for nothing.
