Subject2.5.58-mjb1 (scalability / NUMA patchset)
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 anyone willing to test on any platform, however large or small.

Since 2.5.55-mjb1

The interrupt distribution on Summit should be fixed now.
I put the new minimal NUMA scheduler in, no node-balance code yet (real soon).
The summit code will break the new bigsmp subarch for now.
