There have been only two minor changes from the last take[L]. * work_buf initialization in stop_one_cpu_nowait() simplified. * Comment to clarify active_balance_work synchronization added. Peter, if you ack the series, I'll add refresh the patches w/ your ACK and request pull into sched/core to Ingo. This patchset contains the following four patches. 0001-cpu_stop-implement-stop_cpu-s.patch 0002-stop_machine-reimplement-using-cpu_stop.patch 0003-scheduler-replace-migration_thread-with-cpu_stop.patch 0004-scheduler-kill-paranoia-check-in-synchronize_sched_e.patch The patches are against the current linux-2.6-tip/sched/core (99bd5e2f245d8cd17d040c82d40becdb3efd9b69) and are available in the following git tree. git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git cpu_stop diffstat follows.
