May as well rename the function mmu_node_end(). I was worried if it
was used anywhere else, but it turned out it's only used when defining
the interval tree.

I would also suggest moving this function (as well as mmu_node_first)
right before its use, rather than just after, which would allow you to
also remove the function prototype a few lines earlier.

Looks good to me otherwise.
