[PATCH] x86_64 irq: Refactor setup_IO_APIC_irq
Currently we have two routines that do practically the same thing setup_IO_APIC_irq and io_apic_set_pci_routing. This patch makes setup_IO_APIC_irq the common factor of these two previous routines. For setup_IO_APIC_irq all that was needed was to pass the trigger and polarity to make the code a proper subset of io_apic_set_pci_routing. Hopefully consolidating these two routines will improve maintenance there were several differences that simply appear to be one routine or the other getting it wrong. Signed-off-by: Eric W.
