[Suzuki K. Poulose]

From: "Suzuki K. Poulose" <suzuki.poulose at arm.com>

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.

This series hasn't changed since V1, except for better commit messages.

Similar fixes are required in ARM-CCN PMU driver and is not straight forward
as these changes.

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