Suzuki K Poulose 5b50468a2d KVM: arm64: Disable guest access to trace filter controls ... [ Upstream commit a354a64d91 ] Disable guest access to the Trace Filter control registers. We do not advertise the Trace filter feature to the guest (ID_AA64DFR0_EL1: TRACE_FILT is cleared) already, but the guest can still access the TRFCR_EL1 unless we trap it. This will also make sure that the guest cannot fiddle with the filtering controls set by a nvhe host.
