And now you've just broken every non-blackfin nommu platform, as you've
only defined MAP_SPLIT_PAGES in asm-blackfin/mman.h.

And what is this? It only shows up in the blackfin defconfig. This is not

No real objections to the approach, but it would be nice if these sorts
of things were test compiled for at least one platform that isn't yours,
so the obviously broken stuff is fixed before it's posted and someone
else has to find out about it later.
