[VIRT-263 # ARMv8.1-VHE Virtual Host Extensions ]

Picked up my partial patch set and started on it again. It is improved by having done the pauth/bti/mte work. But still a work in progress.

[VIRT-327 # Richard's upstream QEMU work ]

Version 3 of tcg/ppc vector instructions. Reviewed target/rx v4.

Fixed thread=single expansion of casp after Alex did all the hard work tracking down the kernel failure, and writing me a test case.

Looking into the size of the softmmu tlb expansion. Current thinking is to move tlb out of CPUArchState into a new struct that precedes env, so that the tlb is at small negative offsets from env, so that {mask, table} is loadable with LDP/LDRD.
