From 6a60f9e7d8bb3e81fa8bd6752f1473e216424ec4 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Tue, 4 Jun 2013 19:38:54 +0000 Subject: powerpc/power8: Fix oprofile and perf 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.
