Lorenzo Pieralisi 0d368cb06e unicore32/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks ... The pci_fixup_irqs() function allocates IRQs for all PCI devices present in a system; those PCI devices possibly belong to different PCI bus trees (and possibly rooted at different host bridges) and may well be enabled (ie probed and bound to a driver) by the time pci_fixup_irqs() is called when probing a given host bridge driver. Furthermore, current kernel code relying on pci_fixup_irqs() to assign legacy PCI IRQs to devices does not work at all for hotplugged devices in that the code carrying out the IRQ fixup is called at host bridge driver probe time, which just cannot take into account devices hotplugged after the system has booted. The introduction of map/swizzle function hooks in struct pci_host_bridge allows us to define per-bridge map/swizzle functions that can be used at device probe time in PCI core code to allocate IRQs for a given device (through pci_assign_irq()). Convert PCI host bridge initialization code to the pci_scan_root_bus_bridge() API (that allows to pass a struct pci_host_bridge with initialized map/swizzle pointers) and remove the pci_fixup_irqs() call from arch code.
