- removes unused (and unnecessary) hooks in swiotlb. - adds dma_capable() and converts swiotlb to use it. It can be used to know if a memory area is dma capable or not. I added is_buffer_dma_capable() for the same purpose long ago but it turned out that the function doesn't work on POWERPC.
This can be applied cleanly to linux-next, -mm, and mainline. This patchset touches multiple architectures (ia64, powerpc, x86) so I guess that -mm is appropriate for this patchset (I don't care much what tree would merge this though). This is tested on x86 but only compile tested on POWERPC and IA64.
