kfraser@localhost.localdomain 28f7888d7f hvm: Do not save/restore shared_info gpfn location. 
Instead of kludging a max_gpfn estimate in shared_info, add a new
XENMEM command to discover the actual maximum gpfn value as known by
the shadow code.

This needs to be more robust when we support HVM ballooning in future
anyway. One interesting point is that max_gpfn may be close to 4GB
even for small-memory HVM guests since for example SVGA LFB is mapped
into the I/O hole. We may need to special case the I/O hole somehow,
or provide some finer-grained way to find out which parts of the GPFN
space are actually used (e.g., get Xen to fill in a bitmap with 1 bit
per 1024 pages, or similar).

kfraser@localhost.localdomain 4d42d7146c dump-core: store .xen_p2m or .xen_pfn section in pfn ascending order. 
So far the order isn't specified and may be random in theory.
But sorted array is requested by crash utility for efficient search.

Fortunately it is the case except ia64 full virtualized domain.
Update document such that those array must be sorted and fix the ia64
full virtualized domain case.
