If people building universe can't spare an extra 10% of the build time for sun4v (or whatever it is), then we should presumably delete sun4v now, because if it's not in the universe build it will no longer build within weeks, and be quite difficult to get to build within months. > I haven't removed any support for building sun4v.

I think you should consider backing out the change -- the point of "make universe" is to build as much as we possibly can of the tree, including all variations on architectures, as many obscure kernel configurations as we can find, etc. People run make universe to confirm that their changes haven't broken the build for as many cases as possible, and sun4v remains a valid case to detect. If you think we should write off sun4v at this point, which may well be a valid proposal, we should have the larger discussion about that before we remove it from make universe unless we have a pretty practical reason otherwise (i.e., dtrace and sun4v are fundamentally incompatible).
