Idan Horowitz 25e82fb769 softmmu/cpus: Check if the cpu work list is empty atomically ... Instead of taking the lock of the cpu work list in order to check if it's empty, we can just read the head pointer atomically. This decreases cpu_work_list_empty's share from 5% to 1.3% in a profile of icount-enabled aarch64-softmmu.
