Eric B Munson ad5d5292f1 powerpc/oprofile: Handle events that raise an exception without overflowing ... Commit 0837e3242c fixes a situation on POWER7 where events can roll back if a specualtive event doesn't actually complete. This can raise a performance monitor exception. We need to catch this to ensure that we reset the PMC. In all cases the PMC will be less than 256 cycles from overflow. This patch lifts Anton's fix for the problem in perf and applies it to oprofile as well.
