[Qemu-devel] [PATCH for-4.2 00/24] target/arm: Implement ARMv8.1-VHE

[Richard Henderson]

About half of this patch set is cleanup of the qemu tlb handling
leading up to the actual implementation of VHE, and the biggest
piece of that: The EL2&0 translation regime.

Testing so far has been limited to booting a debian 9 system with
a 4.9 kernel, and a fedora 30 system with a 5.1 kernel.  Both have
KVM enabled, and both report enabling VHE is successful.
