Subject: [PATCH] perf: Power7: Make CPI stack events available in sysfs
A set of Power7 events are often used for Cycles Per Instruction (CPI) stack
analysis. Make these events available in sysfs (/sys/devices/cpu/events/) so
they can be identified using their symbolic names:
perf stat -e 'cpu/PM_CMPLU_STALL_DCACHE_MISS/' /bin/ls

Should we take these two via the powerpc tree? Or do you want to take
them Arnaldo?

I think it can go through powerpc tree since it is all arch-specific.

perf: Power7: Make CPI stack events available in sysfs
A set of Power7 events are often used for Cycles Per Instruction (CPI) stack
analysis. Make these events available in sysfs (/sys/devices/cpu/events/) so
they can be identified using their symbolic names:
perf stat -e 'cpu/PM_CMPLU_STALL_DCACHE_MISS/' /bin/ls
