Are you referring to boot-time allocations using get_free_pages()
instead of bootmem? Killing those off would be nice, yes. It limits
the size of some hash tables on larger machines where "proportional
to memory" means "bigger than MAX_ORDER". (Changing the algorithms to
not use gargantuan hash tables might also be an interesting exercise
but one I've not got the bandwidth to take on.)
