This patch reworks the way IRQs are fixed up on PCI for arch powerpc. It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.
