Not really, no. IOAPIC_VERSION, as said, should go away.
Meanwhile I already have a patch for that (at once dropping
IOAPIC_BASE_ADDRESS too), albeit that conflicts with what
you're doing.
And the two PCI_ISA_ ones seem to belong together solely
because of their name. The IRQ mask is a simple number,
unrelated to any specific PCI device.
