Hi,

This patchset removes CPU hotplug's dependence on stop_machine() from the CPU
offline path and provides an alternative (set of APIs) to preempt_disable() to
prevent CPUs from going offline, which can be invoked from atomic context.
The motivation behind the removal of stop_machine() is to avoid its ill-effects
and thus improve the design of CPU hotplug. (More description regarding this
is available in the patches).

If you're doing a v7, please put your benchmark results somewhere!

Oh, I forgot to put them in v6! Thanks for reminding :-)
And yes, I'll have to do a v7 to incorporate changes (if any) to the new code
that went in during this merge window.

The obvious place is in the 44/46.

Ok, will add it there. Thank you!
 
Regards,
Srivatsa S. Bhat
