From 6fee48cd330c68332f9712bc968d934a1a84a32a Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Wed, 10 Mar 2010 15:23:40 -0800 Subject: dma-mapping: arm: use generic pci_set_dma_mask and pci_set_consistent_dma_mask This converts arm to the generic pci_set_dma_mask and pci_set_consistent_dma_mask (removes HAVE_ARCH_PCI_SET_DMA_MASK for dmabounce).
