Looking closer ioapic_renumber_irq does not appear to be an irq
compress thing. Rather it appears to be a work around for a weird
acpi implementation where gsi 0 - 15 are not the ISA irqs.

Natalie is my reading of the code there correct?

If so keeping ioapic_renumber_irq makes sense. Although giving
it a name that suggests it is working around weird implementation
details would be good.
