2.6.0-test9-mjb2

2.6.0-test9-mjb2

[Martin J. Bligh]

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.

Yeah, I think the code in there is pretty ugly ... I think that one
only works as a module right now - sorry.

"copyin" and "copyout" aren't good names for non-static functions:
