Bug Description
On AARCH64, setting HCR.TVM to 1 is supposed to trap all writes to CTLR_EL1, TTBR0_EL1, TTBR1_EL1, TCR_EL1, ESR_EL1, FAR_EL1, AFSR0_EL1, AFSR1_EL1, MAIR_EL1, AMAIR_EL1, and CONTEXTIDR_EL1. However, it currently has no effect (QEMU emulator version 4.1.1).
It is also likely that TRVM will not trap, but, I didn't verify this.
