* remotes/rth-gitlab/tags/pull-tcg-20210205: (46 commits)
  accel: introduce AccelCPUClass extending CPUClass
  accel: replace struct CpusAccel with AccelOpsClass

  cpu: Move tlb_fill to tcg_ops
  cpu: Move cpu_exec_* to tcg_ops
  cpu: Move synchronize_from_tb() to tcg_ops
  accel/tcg: split TCG-only code from cpu_exec_realizefn
