Why?

Considering this:

+#ifdef CONFIG_SPARSEMEM
+ /*
+ * SECTION_SIZE_BITS            2^N: how big each section will be
+ * MAX_PHYSADDR_BITS            2^N: how much physical address space we have
+ * MAX_PHYSMEM_BITS             2^N: how much memory we can have in that space
+ */

The virtual mem-map seems like a much nicer solution to me.
