Progress: * UM-2 [QEMU upstream maintainership] - Noticed that if the guest uses the HVC insn at EL3 we incorrectly take the exception to EL2, not EL3; sent a patch to fix this - looking into an issue with FEAT_MOPS copies going backwards across page boundaries * QEMU-292 [ARMv8.3 FEAT_NV, Nested Virtualization] - realised we need to do some cleanup of how we handle the FEAT_VHE register aliases, as the way we currently do them makes the FEAT_NV register trapping a little awkward. Wrote the necessary patches; they'll go into the FEAT_NV patchset when it's eventually ready to send out.
