HVM_PARAM_CONSOLE_PFN is used to retrieved the console PFN for HVM
guest. It returns a PFN (aka GFN) and not a MFN.
Furthermore, use directly virt_to_gfn for both PV and HVM domain rather
than doing a special case for each of the them.

Hi all,
This patch series aims to use the memory terminologies described in
include/linux/mm.h [1] for Linux xen code.
I mistakenly wrote the wrong include here. It should be include/xen/mm.h
from the Xen tree:
http://xenbits.xen.org/gitweb/?p=xen.git
I'd suggest ...replace any reference to mfn with gfn...
[...]
Thanks for telling me the typoes. I will fix it in the next version of
this series.
