Subject: [PATCH] perf_counter/powerpc: Fix cache event codes for POWER7

I had the codes for L1 D-cache load accesses and misses swapped around,
and the wrong codes for LL-cache accesses and misses.  This corrects
them.

Ingo, if you have perfcounter fixes that you are going to ask Linus to
pull before .32, please include this.
