It would be ideal to find
some way to handle ia64 and ARM64 similarly.  At the very least, we
have to make sure that this doesn't break ia64.  The ia64 dense/sparse
I/O spaces complicate things; I don't know if ARM64 has something
similar or not.

There's nothing directly similar - it's just regular MMIO.

Just a footnote on the IA64 thing. I'm working on getting access to a
few Itanium systems and running V6 on these (even bought my first
Itanium system today so I can run this at home also). I'm also chatting
with the internal RH QE folks about testing on a few dozen x86 systems.
Will followup when we've any results on that testing.

Jon.
