The mm-sources were based on vanilla-sources and contained Andrew Morton's patch set. They included the experimental and bleeding-edge features that were going to be included in the official kernel (or were going to be rejected because they set systems on fire!). They were known to be always moving at a fast pace and could change radically from one week to the other; kernel hackers often used mm-sources as a testing ground for highly experimental stuff. They have since been removed from the Portage tree.
