I will be making : SP (single processor) patch sets available tonight or tomorrow : morning.

May I request that you don't check in the new MP core until the SP issues have been resolved? I don't care if the MP boxes have major pain after the commit date (that's rather the point of all the new MP work), but have some serious issues if the SP boxes have major pain. It wasn't clear from the orignial message if the major pain and bleeding is for all users, or just MP users. It would be extremely hard to make forward progress on anything while the pain is there. For a few days or even a couple of weeks this would be OK, but for months that is not acceptible to me. I'm trying to get NEWCARD finished, as well as start the cardbus work and those two projects are being done in -current. There's no pain to non-laptop users (in fact, there's currently no pain to laptop users that use the old system). It is extremely desirable to have the current tree buildable and stable for SP machines during this transition. Please note, this isn't an attempt to disparage your work, or to try to get overly in the way of it. I'm merely trying to keep the SP world relatively stable while the MP work is going on. Ther'es a 6 year tradition of having -current be basically usable for developers to develop in that I'd like to continue.
