When steal_context is used on SMP systems, it can steal a context in

prevent this as suggested by BenH.
Can we be more descriptive in the problem/bug symptom in the
description.
otherwise this looks ok to me. I'd like BenH to ack as well since
he's been look at this code recently.

The previous version of this patch had some unnecessary code which
has been
removed in this version.
Note: This is a proof-of-concept patch. This isn't my area of
expertise,
so I'd greatly appreciate any guidance I can get. I'm considering the
use of for_each_online_cpu() instead of for_each_possible_cpu() and
possibly putting the changes under a CONFIG_SMP switch to prevent
unnecessary
overhead in the non-SMP case.
for_each_online_cpu() is probably better. I'm guessing this optimizes
pretty well in the !CONFIG_SMP case.
