Hi,
this is the patch for error reporting on ia64 that has a special 
handling in comparison with i386/x86_64 platforms. This is pretty 
straight-forward just to fail on "cannot map mfn page" message instead 
of continue since the memory is not being correctly mapped using the 
xc_map_foreign_range() function.

This patch has been originally done for RHEL-5 version of Xen, tested 
and working fine on RHEL-5 but when I had a look at Xen-unstable I saw 
that is *may* be the issue there as well. Unfortunately I'm not having 
any ia64 machine where I can install Xen-unstable so could somebody 
please test this patch on Xen-unstable ? Nevertheless, since the code is 
pretty similar for both RHEL-5 Xen and Xen-unstable it should work the 
same, i.e. it should be working but unfortunately I can't test it :(

Thanks a lot,
Michal
