Merge branch 'pci/header-cleanup-immutable'
- Remove pci_get_legacy_ide_irq(); use ATA_PRIMARY_IRQ() and ATA_SECONDARY_IRQ() instead (Stafford Horne) - Remove isa_dma_bridge_buggy, except for x86_32, the only place it's used (Stafford Horne) - Define ARCH_GENERIC_PCI_MMAP_RESOURCE for csky (Stafford Horne) - Move common PCI definitions that arches sometimes override to asm-generic/pci.h (Stafford Horne) - Include <linux/isa-dma.h> for 'isa_dma_bridge_buggy' when needed (bisection hole here) (Randy Dunlap) * pci/header-cleanup-immutable: PCI: Stub __pci_ioport_map() for arches that don't support it at all x86/cyrix: include header linux/isa-dma.h asm-generic: Add new pci.h and use it csky: PCI: Define ARCH_GENERIC_PCI_MMAP_RESOURCE PCI: Move isa_dma_bridge_buggy out of asm/dma.h PCI: Remove pci_get_legacy_ide_irq() and asm-generic/pci.h
