We're not quite to the point of bringing up networking
yet but in digging through the mailing list archive,
I was reminded of a problem that we will soon run into:
Xenlinux/x86 utilizes the PG_arch_1 bit to represent
a "foreign" page.  Linux/ia64 (and I think Linux/ppc)
use the PG_arch_1 bit for arch-dep purposes.

It this conflict is not resolved before Xenlinux/ia64
supports networking, there will likely be some very
interesting bugs...


What is the actual issue here? Where is the code dealing with PG_arch_1?
