Great!!!

One thing I've never been sure about are these definitions in sparsemem.h.

/*
 * 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
 */
#define SECTION_SIZE_BITS       24
#define MAX_PHYSADDR_BITS       38
#define MAX_PHYSMEM_BITS        36

Do you know if these are sufficient for all supported hardware today?

Thanks,
