[PATCH 0/4] KVM: arm64: PMU fixes for 6.13

[Oliver Upton <oliver.upton@linux.dev>]

Small set of fixes for PMU, mostly focused on plugging gaps in nested
support that I'd missed last time around:

 - Don't attempt to enable/disable EL2 counters when PMCR_EL0.E is
   changed. This is already the case since the enable state of a
   counter is re-evaluated in kvm_pmu_create_perf_event(), though the
   handling of PMCR_EL0.E would suggest otherwise.

 - Enable/disable EL2 counters when MDCR_EL2.HPME is changed.

 - Only reset 'guest' counters when PMCR_EL0.P is set, excluding EL2
   counters from being reset.

Applies to 6.13-rc3, tested on the M2 w/ my PMUv3 patches thrown on top.

Oliver Upton (4):
  KVM: arm64: Add unified helper for reprogramming counters by mask
  KVM: arm64: Use KVM_REQ_RELOAD_PMU to handle PMCR_EL0.E change
  KVM: arm64: nv: Reload PMU events upon MDCR_EL2.HPME change
  KVM: arm64: Only apply PMCR_EL0.P to the guest range of counters
