Hi,
I've digged more, and I could successfully use two AVAIL bits in PTEs,
Actually xen doesn't use AVAIL bits, and Linux doesn't use (all of) them, either. Good so far, but still some issues still remains, but I'm working on it but I think I can handle it. 
Anyway, thanks, Mike. :)

Hmm, I'm not so familiar with PV guests in 3.2.x.  Let me try and take
a look and see if I can get back to you.

Mike
