| Power7 supports over 530 different perf events but only a small
| subset of these can be specified by name, for the remaining
| events, we must specify them by their raw code:
| 
|         perf stat -e r2003c <application>
| 
| This patch makes all the POWER7 events available in sysfs.
| So we can instead specify these as:
| 
|         perf stat -e 'cpu/PM_CMPLU_STALL_DFU/' <application>
| 
| where PM_CMPLU_STALL_DFU is the r2003c in previous example.
| 
| Before this patch is applied, the size of power7-pmu.o is:
| 
| $ size arch/powerpc/perf/power7-pmu.o
|    text	   data	    bss	    dec	    hex	filename
|    3073	   2720	      0	   5793	   16a1	arch/powerpc/perf/power7-pmu.o
| 
| and after the patch is applied, it is:
| 
| $ size arch/powerpc/perf/power7-pmu.o
|    text	   data	    bss	    dec	    hex	filename
|   14451	  31112	      0	  45563	   b1fb	arch/powerpc/perf/power7-pmu.o
