Bjorn Helgaas fe537670ea PCI: Consolidate PCI DMA constants and interfaces in linux/pci-dma-compat.h 
Christoph added a generic include/linux/pci-dma-compat.h, so now there's
one place with most of the PCI DMA interfaces.  Move more PCI DMA-related
things there:

  - The PCI_DMA_* direction constants from linux/pci.h
  - The pci_set_dma_max_seg_size() and pci_set_dma_seg_boundary()
    CONFIG_PCI implementations from drivers/pci/pci.c
  - The pci_set_dma_max_seg_size() and pci_set_dma_seg_boundary()
    !CONFIG_PCI stubs from linux/pci.h
  - The pci_set_dma_mask() and pci_set_consistent_dma_mask()
    !CONFIG_PCI stubs from linux/pci.h

Christoph Hellwig bc4b024a8b PCI: Move pci_dma_* helpers to common code 
For a long time all architectures implement the pci_dma_* functions using
the generic DMA API, and they all use the same header to do so.

Move this header, pci-dma-compat.h, to include/linux and include it from
the generic pci.h instead of having each arch duplicate this include.
