Merge branch 'pci/header-cleanup-immutable'

Browse Source 
- 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
