2.5.50-mjb1 (scalability / NUMA patchset)

From: Martin J. Bligh (mbligh@aracnet.com)

The patchset contains mainly scalability and NUMA stuff, and
anything else that stops things from irritating me. It's meant
to be pretty stable, not so much a testing ground for new stuff.
I'd be very interested in feedback from other people running
large SMP or NUMA boxes.


Since 2.5.47-mjb3:

merged by Linus:
- noearlyirq Martin Bligh et al.

all screwed up at the moment:
