Subject[PATCH -mm 00/12] adds include/asm-generic/pci-dma-common.h
Date
This patchset adds include/asm-generic/pci-dma-common.h that defines
the pci_unmap state API:

DECLARE_PCI_UNMAP_ADDR(ADDR_NAME)
DECLARE_PCI_UNMAP_LEN(LEN_NAME)
pci_unmap_addr(PTR, ADDR_NAME)
pci_unmap_addr_set(PTR, ADDR_NAME, VAL)
pci_unmap_len(PTR, LEN_NAME)
pci_unmap_len_set(PTR, LEN_NAME, VAL)

This enables us to remove lots of the duplication in architecture
implementations since there are only two ways to define the API.

If architectures define HAVE_ARCH_PCI_UNMAP, they get the real
definition of pci_unmap state API. If not, they get the noop
definition.

In the long term, it's better to replace the API with the generic
device model API such as DECLARE_DMA_UNMAP_ADDR. We can map the API to
the generic one (like dma-mapping-compat.h does). This patch also
makes the migration process easier.
