I'm speaking specifically in terms of 64-bit platforms here. Shouldn't
we unconditionally drop outb_p doing extra port I/O on 64-bit
architectures? Especially considering they don't even have an ISA bus
where the decode timing could even matter?
Why should the bitsize of the CPU matter for this? It seems one of the
less meaningful keys for this.
Second, as I have mentioned, I don't believe this is really the case,
especially not for the PIT, which is still present -- the PIT
*semantics* has explicit timing constraints.
Third, you still have ISA devices, they're just called LPC or PC104
devices these days.
