Richard already picked up this patch:
  tcg: consistently access cpu->tb_jmp_cache atomically
  https://patchwork.kernel.org/patch/9787697/

The patch you're sending (i.e. 1/7) is a subset of that one,
so the easiest solution probably is to drop it, making sure that:
- patch 4/7 is updated to call cpu_tb_jmp_cache_clear instead of
  tb_flush_jmp_cache_all
- This series is merged after that other patch is merged. If
  Richard also queues then we'll be guaranteed to avoid a merge
  conflict.
