Subject[PATCHSET sched/core] cpu_stop: implement and use cpu_stop
Date
Hello, all.

cpu_hog has been renamed to cpu_stop and moved into
kernel/stop_machine.c per Peter Zijlstra's suggestion. This patchset
is feature-wise identical to the second take of cpuhog[L]. The only
changes are the rename, relocation and refresh against the current
sched/core.

The following API renames took place.

- hog_one_cpu() -> stop_one_cpu()
- hog_one_cpu_nowait() -> stop_one_cpu_nowait()
- hog_cpus() -> stop_cpus()
- try_hog_cpus() -> try_stop_cpus()
- *_hog() callbacks -> *_cpu_stop()

Internal names have been renamed accordingly. e.g. cpuhog thread
became cpu_stopper thread and so on.

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
(09a40af5240de02d848247ab82440ad75b31ab11) and are available in the
following git tree.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git cpu_stop

I retained the original acked/reviewed-by's as the changes are mostly
cosmetic. If you disagree, please let me know. I'll try to push this
through sched/core again once Peter acks.

diffstat follows.
