[PATCH 0/3] cpus: Avoid re-initializing fields cleared in cpu_common_reset_hold()

[Philippe Mathieu-Daudé]

Having this call tree:

  cpu_reset()
  -> device_cold_reset()
     -> DeviceClass::reset()
        -> target_cpu_reset()
           -> ResettablePhases::hold()
              -> CPUClass::phases::hold()
                 -> cpu_common_reset_hold()

If we call cpu_reset(), common fields will be reset in
cpu_common_reset_hold(), we don't need to manually do it.

Remove the pointless re-assignments on CPUState.

Based-on: <20241230152519.86291-1-philmd@linaro.org>

Philippe Mathieu-Daudé (3):
  accel/tcg: Remove pointless initialization of cflags_next_tb
  target/cpus: Remove pointless re-assignment of
    CPUState::exception_index
  target/cpus: Remove pointless re-assignment of CPUState::halted
