Merge branch kvm-arm64/pmevtyper-filter into kvmarm/next
* kvm-arm64/pmevtyper-filter:
: Fixes to KVM's handling of the PMUv3 exception level filtering bits
:
: - NSH (count at EL2) and M (count at EL3) should be stateful when the
: respective EL is advertised in the ID registers but have no effect on
: event counting.
:
: - NSU and NSK modify the event filtering of EL0 and EL1, respectively.
: Though the kernel may not use these bits, other KVM guests might.
: Implement these bits exactly as written in the pseudocode if EL3 is
: advertised.
KVM: arm64: Add PMU event filter bits required if EL3 is implemented
KVM: arm64: Make PMEVTYPER<n>_EL0.NSH RES0 if EL2 isn't advertised
