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
