Maybe I'm missing something here.
I couldn't find leul_to_cpu(), so have defined it in bswap.h.

I have previously posted a variant of part 6, to address the problem
of the host returning mmap results that are not page aligned for the

Use TARGET_PHYS_ADDR_SPACE_BITS for the physical memory map based off
of l1_phys_map. This rewrites page_phys_find_alloc and
phys_page_for_each.
The addr < end comparison prevents the last page from being
iterated; an iteration based on length avoids this problem.

This isn't a problem with qemu as such, but it may affect you if you
