    dma-mapping.h: add the dma_unmap state API · 0acedc12
    FUJITA Tomonori authored
    Adds the following macros:
    dma_unmap_addr(PTR, ADDR_NAME)
    dma_unmap_addr_set(PTR, ADDR_NAME, VAL)
    dma_unmap_len(PTR, LEN_NAME)
    dma_unmap_len_set(PTR, LEN_NAME, VAL)
    The API corresponds to the pci_unmap state API.  We'll move to this new
    generic API from the PCI specific API in the long term.  As
    include/asm-generic/pci-dma-compat.h does, the pci_unmap API simply calls
    the new generic API for some time.
