Ok, well, I wasn't expecting to take on a big rename like that as it
would create a patch touching a bunch of arches and mm files... But if
we can come to some agreement on a better name and someone is willing to
take that patch without significant delay then I'd be happy to create
the patch and add it to the start of my series.

Some ideas for new names:

mark_memory_present() / mark_memblocks_present()
set_memory_present() / set_memblocks_present()
memory_register() / memblocks_register()
register_memory() / register_memblocks()
