Basically MIPS is currently without an active maintainer, so
people submitting patches need to keep pinging them until
one of the core maintainers (usually Blue Swirl) applies them.
For this purpose the usual approach is to follow up to the patch
mail saying "Ping" and giving a url to the patch in patchwork,
like this one:
http://patchwork.ozlabs.org/patch/163705/

Eventually somebody will take pity on it and apply it, but
it does require a bit more persistence than for more actively
maintained areas of the codebase.
