[PATCH 00/16] cpus: Improvements around BQL locking, improving docstring

["Philippe Mathieu-Daudé" <philmd@oss.qualcomm.com>]

Hi,

While working on the hybrid-accelerator, I had to debug issues
with vCPU scheduling and BQL. This series contains patches I
wrote mostly as note for myself to better understand what was
going on. Please review carefully as I'm way out of my confort
zone...

Thanks,

Phil.

Philippe Mathieu-Daudé (16):
  accel: Label outer / inner vCPU execution loops
  cpus: Improve qemu_cpu_kick_self() docstring
  cpus: Rename cpu_stop_current() -> qemu_cpu_stop_self()
  cpus: Rename qemu_cpu_stop() to qemu_cpu_ack_stop_request()
  cpus: Improve cpu_pause() docstring
  cpus: Improve cpu_exit() docstring
  cpus: Document process_queued_cpu_work*() runs on current vCPU
  cpus: Slightly improve *run_on_cpu() docstrings
  accel/tcg: Use RUN_ON_CPU_NULL for tcg_commit() callbacks
  accel/kvm: Clarify use of @r variable in vcpu thread loop
  accel/kvm: Consistently return CPU halt state from
    process_async_events
  target/arm/hvf: Move flush_cpu_state() into the inner vCPU loop
  target/arm/hvf: Lock BQL outside of the vCPU inner execution loop
  target/i386/hvf: Lock BQL outside of the vCPU inner execution loop
  target/arm/powerctl: Move BQL assertions to async work context
  target/arm/whpx: Fix argument order typo in memory access error
