This patch significantly accelerates IDE PIO on HVM/IA64:
* reduces the installation time of Windows 2003 Server
from 10 hours(!) to 50min.
* accelerates Windows CrashDumping speed from 40KB/sec
(It takes over three hours for 512MB guest) to 850KB/sec.
All reason for above slowness is the
Allocate frame table/mpt table at mfn=0 even when memory isn't assigned at
mfn=0 as work around of transate_domain_pte().
It returns mfn=0 when the machine page isn't present as a work around
for memory mapped I/O where no device is assigned.
Xen might access page_info of mfn=0, so it must be

A question:
Since IA32 has used gpfn, why these code still in populate_physmap()?

Don't forget IA64 code!
Thanks

linux-2.6.16.33-xen/.config automatically.
See attachment defbuild.patch.
Pae_new_config is used to build x86_32 with PAE enabled.
