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.


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 ?

arm/pmu: Reject groups spanning multiple hardware PMUs
arm64/pmu: Reject groups spanning multiple HW PMUs
arm-cci: Reject groups spanning multiple HW PMUs
