Based on mm-new.

Align some APIs with recent cleanups [0][1], and hide more mm-internal APIs
from public headers.

Part of this was also proposed by Vlastimil right as I was writing it:
https://lore.kernel.org/all/ed4572f4-0074-45c5-993d-7b6533eddc31@kernel.org/

And just like with my other recent patches, this has the ulterior motive
of enabling later incoming patches to add alloc_flags arguments to these
internal functions. (But, I do think these are justified as cleanups in
their own right).
