On non-privileged domain of Xen/IA64, this caused some trobles.
I put this in for now but, in general the SIF_PRIVILEGED flag is only
set for domain0 and not for other driver domains. Your problem is
probably that the guest gives up memory and then cannot reclaim it when
the get-contiguous-region request fails, so it then crashes. I'm fixing
this by adding an atomic memory-exchange hypercall -- when I've added
that you can fix up your create_contiguous_region and I'll remove this
change to the skbuff allocation code.
