* remotes/bonzini/tags/for-upstream-mttcg:
  tcg: move locking for tb_invalidate_phys_page_range up
  *_run_on_cpu: introduce run_on_cpu_data type
  cpus: re-factor out handle_icount_deadline
  tcg: cpus rm tcg_exec_all()
  tcg: move tcg_exec_all and helpers above thread fn
  target-arm/arm-powerctl: wake up sleeping CPUs
  tcg: protect translation related stuff with tb_lock.
  translate-all: Add assert_(memory|tb)_lock annotations
  linux-user/elfload: ensure mmap_lock() held while setting up
  tcg: comment on which functions have to be called with tb_lock held
  cpu-exec: include cpu_index in CPU_LOG_EXEC messages
  translate-all: add DEBUG_LOCKING asserts
  translate_all: DEBUG_FLUSH -> DEBUG_TB_FLUSH
  cpus: make all_vcpus_paused() return bool
