Subject: [kvm-unit-tests PATCH v9 0/3] ARM PMU tests

Changes from v8:
* Probe PMU version based on ID_DFR0
* pmccntr_read() now returns 64bit and can handle both 32bit and 64bit
  PMCCNTR based on PMU version.
* Add pmccntr_write() support
* Use a common printf format PRId64 to support 64bit variable smoothly in
  test functions
* Add barriers to several PMU write functions
* Verfied on different execution modes

Note:
1) Current KVM code has bugs in handling PMCCFILTR write. A fix (see
below) is required for this unit testing code to work correctly under
KVM mode.
