Cc'ing ppc/s390x maintainers -- I'm not sure they've seen this series. Link to this thread (v3): https://lists.gnu.org/archive/html/qemu-devel/2018-10/msg00598.html I'm eager to get this merged, particularly for i386 where it is fixing unnecessary exits via exec_atomic for cmpxchg16 emulation. Thanks, Emilio
