[Xen-devel] Max gfn?

I have a 12GB 64-bit Linux HVM guest (CentOS 5.5). When I look at the
e820 map in the guest, I see the following:

BIOS-provided physical RAM map:
 BIOS-e820: 0000000000010000 - 000000000009e000 (usable)
 BIOS-e820: 000000000009e000 - 00000000000a0000 (reserved)
 BIOS-e820: 00000000000e0000 - 0000000000100000 (reserved)
 BIOS-e820: 0000000000100000 - 00000000f0000000 (usable)
 BIOS-e820: 00000000fc000000 - 0000000100000000 (reserved)
 BIOS-e820: 0000000100000000 - 000000030f000000 (usable)

I see that the highest usable gpa is over 12GB due to the reserved
slots and the max gfn is 30f000.  If I use xc_domain_getinfolist() and
look at max_pages, it returns 300100 which correctly reflects 12GB.
But is there a way for me to find out the max gfn that is reflected in
the guest using libxc?
