In 2ac6f42 powerpc/cputable: Fix oprofile_cpu_type on power8 we broke all power8 hw events. This reverts this change and uses oprofile_type instead. Perf now works on POWER8 again and oprofile will revert to using timers on POWER8. Kudos to mpe this fix. Signed-off-by: Michael Neuling <mikey@neuling.org> --- tag: for-3.10 v2: renamed patch
