Subject2.5.59-mjb6 (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 2.5.59-mjb5 (~ = changed, + = added, - = dropped)

Notes:
Fixed bug between NFS and dcache, and some oprofile bug on UP.
4K stacks are back and crash dump support has arrived (thanks to Suparna
for help merging and bufixing)
