Oliver Upton e0b5a7967d KVM: arm64: nv: Use FGT write trap of MDSCR_EL1 when available ... Marc reports that the performance of running an L3 guest has regressed by 60% as a result of setting MDCR_EL2.TDA to hide bad architecture. That's of course terrible for the single user of recursive NV ;-) While there's nothing to be done on non-FGT systems, take advantage of the precise write trap of MDSCR_EL1 and leave the rest of the debug registers untrapped.
