Poulose" This is a collection of fixes which denies grouping hardware events from different PMUs. They also fix crashes triggered by perf_fuzzer on Linux-4.0-rc2. Pawel, Similar fix is required in ARM CCN PMU driver. I didn't find it straight forward to fix it there. Could you please take a look into it ? Suzuki K.
