2.6.0-test11-mjb2

["Martin J. Bligh" <mbligh@aracnet.com>]

The patchset contains mainly performance, 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 anyone willing to test on any 
platform, however large or small.
