Oliver Upton 74158a8cad KVM: arm64: Skip instruction after emulating write to TCR_EL1 ... Whelp, this is embarrassing. Since commit 082fdfd138 ("KVM: arm64: Prevent guests from enabling HA/HD on Ampere1") KVM traps writes to TCR_EL1 on AmpereOne to work around an erratum in the unadvertised HAFDBS implementation, preventing the guest from enabling the feature. Unfortunately, I failed virtualization 101 when working on that change, and forgot to advance PC after instruction emulation. Do the right thing and skip the MSR instruction after emulating the write.
