* pci_map_sg() -> dma_map_sg() in ide_build_sglist(). * pci_unmap_sg() -> dma_unmap_sg() in ide_destroy_dmatable(). There should be no functionality changes caused by this patch except for blackfin arch whose dma_[un]map_sg() implementation differs from pci_[un]map_sg() one (on s390 arch there is no PCI, on avr32 and h8300 archs PCI is currently unsupported, on m32r arch PCI support depends on BROKEN, on m68k arch PCI support depends on HADES which in turn depends on BROKEN, on all other archs dma_[un]map_sg() functionality matches with pci_[un]map_sg() one). Cc: Bryan Wu <bryan.wu@xxxxxxxxxx> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx> --- It seems like blackfin arch should be using <asm-generic/pci-dma-compat.h> in <asm-blackfin/pci.h> or drivers still using PCI DMA-mapping API instead of the generic one won't work but I'll leave this to blackfin gurus...
