Hi, This doesn't change much from v2 earlier this week:
https://lists.nongnu.org/archive/html/qemu-devel/2017-04/msg00661.html There was a minor improvement to the cpu_update_icount to not use a potentially expensive atomic_add (which is CST) when you can get away with weaker semantics with a single writer. I've also fixed a compile error on 32bit guests. It only falls back to non-atomic code if CONFIG_ATOMIC64 is not set which isn't the case for ARMv7 as it can use load/store-exclusive pair to do the operation. This does require using the __no_check atomic variants though. I still plan to roll a pull-request on Monday and get it sent to Peter in good time for cutting -rc4.
