I think your approach could work (reverse map by having separate address

Note that since we count page->index in PAGE_SIZE unit we
have PAGE_SIZE times as much space as a process can take,
so we definately have enough address space to come up with
a creative allocation scheme.

What happens when you have more than PAGE_SIZE processes running?
