[PATCH v2 0/4] kvm-arm64: Fix PMU reset values (and more)

[Marc Zyngier <maz@xxxxxxxxxx>]

This is the second version of the series initially posted at [1].

* From v1:
  - Simplified masking in patch #1
  - Added a patch dropping PMSWINC_EL0 as a shadow register, though it
    is still advertised to userspace for the purpose of backward
    compatibility of VM save/restore
  - Collected ABs/RBs, with thanks
