Apart from the final set of architecture reviewed-by's the following patches have had minor tweaks: tcg: handle EXCP_ATOMIC exception for system emulation Fixed to handle yet another corner case of tb-flush being triggered during an EXCP_ATOMIC exceptions. Also the mmap_lock is now correctly taken (as EXCP_ATOMIC can be taken for linux-user). tcg: remove global exit_request In the single threaded round robin we also check for cpu->queued_work_first and bail the loop if needed. Otherwise we run into strangeness when the "target-arm: ensure all cross vCPUs TLB flushes complete" runs in single-threaded mode. The tail end of the commit message has been tweaked to explain this. tcg: enable thread-per-vCPU Pranith found a regression running linux-user tests/atomic_bench which was due to the fact we previously removed a setting of cpu->exit_request to 0 in cpu_handle_interrupt. Because the linux-user loop doesn't have the outer loop of system emulation this caused it to hang - always exiting the TB. There was a knock on effect w.r.t to safe work for single-threaded execution but this was fixed in commit above. So if you are happy are you going to be able to submit the pull request before the soft-freeze kicks in? Regards, Alex.
