Maybe yet another vsprintf extension?

Maybe %pH<vartype> where vartype is one of [hh, h, u, ul, ull]
with something like
	u64 t1 = (u64)*(appropriate cast)vartype;
	u64 t2 = t1;
	int index = 0;
	while ((t1 >>= 10)) {
		index++;
		t2 >>= 10;
	}
	
to output the equivalent of
	%llu%s, t2, "bkmgtpezy"[index]
ala dump_pagetables
