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 Signed-off-by: Oliver Upton <oliver.upton@linux.dev>
