[PATCH v2 1/9] cpus: Export queue work related fields to cpu.h |
Date: |
Fri, 23 Jul 2021 15:34:36 -0400 |
This patch has no functional change, but prepares for moving the function
do_run_on_cpu() into softmmu/cpus.c. It does:
1. Move qemu_work_item into hw/core/cpu.h.
2. Export queue_work_on_cpu()/qemu_work_cond.
All of them will be used by softmmu/cpus.c later.
