I am extremely interested in big pages (64K, etc), and the sooner the better. If there is anything not considered OK for immediate inclusion in the Linux MIPS git tree, I would love to have a copy anyway. Large pages will be necessary for some high-priority work I'm doing, although stability at this point seems to be an optional extra. (Hence why the patches are much more important than whether they're actually finished yet.)
