All prerequisites are upstream.  There are still outstanding patches
to improve the atomic16 support, but those are all optimizations.

Patches needing r-b:
  01-target-arm-Add-commentary-for-CPUARMState.exclusi.patch
  03-target-arm-Introduce-finalize_memop_-atom-pair.patch
  04-target-arm-Use-tcg_gen_qemu_ld_i128-for-LDXP.patch
  05-target-arm-Use-tcg_gen_qemu_-st-ld-_i128-for-do_f.patch
  16-target-arm-Relax-ordered-atomic-alignment-checks-.patch
  18-tests-tcg-aarch64-Use-stz2g-in-mte-7.c.patch
