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.

NOTE - you will have to apply -bk3 before applying this release.



Since 2.5.64-mjb1 (~ = changed, + = added, - = dropped)
