Hello Rusty,

I'have just started to read the code (and I'm not an expert kernel
programmer), but is this condition ok ?


(function setup_pagetables(), on file Documentation/lguest.c )

   /* Ideally we map all physical memory starting at page_offset.
    * However, if page_offset is 0xC0000000 we can only map 1G of physical
    * (0xC0000000 + 1G overflows). */

   if (mem > -page_offset)
       mapped_pages = mem/getpagesize();
   else
       mapped_pages = -page_offset/getpagesize();



Cheers

Matias
