Yinghai Lu 181380b702 PCI/ACPI: Don't cache _PRT, and don't associate them with bus numbers ... Previously, we cached _PRT (PCI routing table, ACPI 5.0 sec 6.2.12) contents and associated each _PRT entry with a PCI bus number. The bus number association means dependencies on PCI device enumeration and bus number assignment, as well as on the PCI/ACPI binding process. After 4f535093cf ("PCI: Put pci_dev in device tree as early as possible"), these dependencies caused the IRQ issues reported by Peter: pci 0000:00:1e.0: PCI bridge to [bus 09] (subtractive decode) pci 0000:00:1e.0: can't derive routing for PCI INT A snd_ctxfi 0000:09:02.0: PCI INT A: no GSI - using ISA IRQ 5 irq 18: nobody cared (try booting with the "irqpoll" option) This patch removes _PRT caching. Instead, we evaluate _PRT as needed in the pci_enable_device() path. This also removes the dependency on PCI bus numbers: we can simply look at the _PRT associated with each bridge as we walk upstream toward the root.
