Merge tag 'stable/for-linus-3.8-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb
Pull swiotlb update from Konrad Rzeszutek Wilk: "Feature: - Use dma addresses instead of the virt_to_phys and vice versa functions. Remove the multitude of phys_to_virt/virt_to_phys calls and instead operate on the physical addresses instead of virtual in many of the internal functions. This does provide a speed up in interrupt handlers that do DMA operations and use SWIOTLB." * tag 'stable/for-linus-3.8-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb: swiotlb: Do not export swiotlb_bounce since there are no external consumers swiotlb: Use physical addresses instead of virtual in swiotlb_tbl_sync_single swiotlb: Use physical addresses for swiotlb_tbl_unmap_single swiotlb: Return physical addresses when calling swiotlb_tbl_map_single swiotlb: Make io_tlb_overflow_buffer a physical address swiotlb: Make io_tlb_start a physical address instead of a virtual one swiotlb: Make io_tlb_end a physical address instead of a virtual one
