The list Ok, guys, I've pulled this and pushed out. There were some conflicts with both the VM changes and with the scheduler tree, but they were pretty small and looked simple, so I fixed them up and hope they all work. Has anybody tested the impact on single-node systems? If distros enable this by default (and it does have 'default y', which is a big no-no for new features - I undid that part) then there will be tons of people running this without actually having multiple sockets. Does it gracefully avoid pointless overheads for this case? Anyway, hopefully we'll have a more real numa balancing for 3.9, and this is still considered a reasonable base for that work. Linus
