Roman Skakun 8983766903 dma-mapping: handle vmalloc addresses in dma_common_{mmap,get_sgtable} ... [ Upstream commit 40ac971eab89330d6153e7721e88acd2d98833f9 ] xen-swiotlb can use vmalloc backed addresses for dma coherent allocations and uses the common helpers. Properly handle them to unbreak Xen on ARM platforms.
