I'd prefer the trees to be separate for testing purposes: it doens't make much sense to have SMP support as a normal kernel feature when most people won't have SMP anyway" -- Linus Torvalds Only in this case I can't help feeling that the virtualisation work already bypassed C/R, solved the problem space that a lot of people care about and then moved on.
