Refactor cpu_has_work/any_cpu_has_work in cpus.c Avoid duplicate use of the function name cpu_has_work, it's confusing, also their scope. Refactor cpu_has_work to cpu_thread_is_idle and do the same with any_cpu_has_work. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
