Thanks Laszlo.

I think only the first two patches matter to Xen so I only tested those.
Now I'm able to boot a guest with more than 64GB ram.

Here is what it looks like from a 128 GB guest.

root@debianhvm:~# free -m
             total       used       free     shared    buffers     cached
Mem:         12640        116      12523          0          6         27
-/+ buffers/cache:         82      12558
Swap:        26486          0      26486

Nice work!

Wei.
