It would save me a lot code n my boot stub because i have to initialize
paging in assembly and i need to put all the tables in a contiguous block of memory.
currently i have a presreserved area in bss and i map only the first 4 M
just to start VM. Then i look for the the first unused memory to place
the rest of the paging structures in.
