Merge branch kvm-arm64/6.6/pmu-fixes into kvmarm-master/next
* kvm-arm64/6.6/pmu-fixes:
: .
: Another set of PMU fixes, coutrtesy of Reiji Watanabe.
: From the cover letter:
:
: "This series fixes a couple of PMUver related handling of
: vPMU support.
:
: On systems where the PMUVer is not uniform across all PEs,
: KVM currently does not advertise PMUv3 to the guest,
: even if userspace successfully runs KVM_ARM_VCPU_INIT with
: KVM_ARM_VCPU_PMU_V3."
:
: Additionally, a fix for an obscure counter oversubscription
: issue happening when the hsot profines the guest's EL0.
: .
KVM: arm64: pmu: Guard PMU emulation definitions with CONFIG_KVM
KVM: arm64: pmu: Resync EL0 state on counter rotation
KVM: arm64: PMU: Don't advertise STALL_SLOT_{FRONTEND,BACKEND}
KVM: arm64: PMU: Don't advertise the STALL_SLOT event
KVM: arm64: PMU: Avoid inappropriate use of host's PMUVer
KVM: arm64: PMU: Disallow vPMU on non-uniform PMUVer
