Have you tried just running "make menuconfig" and looking around? That's typically what you do when someone has added optional functionality to a kernel.

Edit: Yep. A quick search shows that UKSM is there. See Processor type and features / Enable KSM for page merging / Choose UKSM/KSM strategy. Finding BFS is left as an exercise to the OP.

By the way, have you intentionally emerged the less-than-latest version? There's a later version than you cite in Portage.
