[VIRT-294 # ARMv8.3-PAuth, Pointer Authentication ]

Finished up the linux-user emulation, and posted. Reviewed a patch set from Huawei also touching PAuth.

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

Reviewed riscv decodetree v4 patchset.

Partial review of new target/rx patchset. It is confusing enough to make me want to tackle the variable-length decodetree problem.

Reviewed softtlb resize v7 patchset; ported that to the remaining tcg backends.

Part way through reviewing Peter's MPS2 patch set.
