This patch series is a rework of an already pushed patch
exposing PMU to the guests. In the second version the vpmu
parameter is common and prework in the form of reporting
availability of vPMU on the hardware is added.

The current status is that the PMU registers are not virtualized
and the physical registers are directly accessible when "vpmu"
parameter is enabled in the guest config file. There is no interrupt
support and Xen will not save/restore the register values on context
switches. This is to be done in the future.

Michal Orzel (3):
  xen+tools: Introduce XEN_SYSCTL_PHYSCAP_vpmu
  xen/arm: Check for PMU platform support
  xen: Expose the PMU to the guests
