Not sure if I'm missing it in the diff, but it looks like there's also a
bunch of "#ifdef __ia64__" and "#ifdef __IA64__" type code spread
throughout the kernel. I didn't look at the actual diff, but it's in
files that aren't showing up in the diffstat.
Just "git grep -i __ia64__" lists a bunch. I didn't look at all of
them, but at least spot checking include/acpi/actypes.h looks like it's
a real Itanium workaround. If the arch goes, it's probbaly worth
removing those too?
There's also some mentions of "Itanium" in Documentation outside that
don't look like they got caught here. Not sure if they'd be worth
getting rid of, though as they could still be useful examples. The
blurb in Documentation/memory-barriers.txt looks pretty port-specific,
though.
