This is not necessarily to help you, specifically. It's to remove the curb for people wanting to beat on the SMP kernel and provide feedback information to the SMP coders without requiring a lot of hand-holding in trade for the (needed) feedback. One effect this should have is that an SMP kernel should be built for the snap's (whech gets it on the CDROM). This won't happen without an "SMP GENERIC config" of some kind. > What was a lot harder was figuring what the options do.

The SMP options also need to be runtime instead of compile time configurable, based on flags values which can be modified at boot configuration time. This would let a single SMP kernel work on all hardware, regardless of which options must be twiddled to get it to go. The alternative is multiple "SMP GENERIC" configurations -- not a likely event. My suggestion was aimed at main-streaming the code so that there would be more feedback, while at the same time offloading some of the issues requring hand-holding to the standard UP kernel channels.
