Merge remote-tracking branch 'stefano/swiotlb-xen-9.1' into stable/for-linus-3.13
* stefano/swiotlb-xen-9.1:
swiotlb-xen: fix error code returned by xen_swiotlb_map_sg_attrs
swiotlb-xen: static inline xen_phys_to_bus, xen_bus_to_phys, xen_virt_to_bus and range_straddles_page_boundary
grant-table: call set_phys_to_machine after mapping grant refs
arm,arm64: do not always merge biovec if we are running on Xen
swiotlb: print a warning when the swiotlb is full
swiotlb-xen: use xen_dma_map/unmap_page, xen_dma_sync_single_for_cpu/device
xen: introduce xen_dma_map/unmap_page and xen_dma_sync_single_for_cpu/device
swiotlb-xen: use xen_alloc/free_coherent_pages
xen: introduce xen_alloc/free_coherent_pages
arm64/xen: get_dma_ops: return xen_dma_ops if we are running as xen_initial_domain
arm/xen: get_dma_ops: return xen_dma_ops if we are running as xen_initial_domain
swiotlb-xen: introduce xen_swiotlb_set_dma_mask
xen/arm,arm64: enable SWIOTLB_XEN
xen: make xen_create_contiguous_region return the dma address
xen/x86: allow __set_phys_to_machine for autotranslate guests
arm/xen,arm64/xen: introduce p2m
arm64: define DMA_ERROR_CODE
arm: make SWIOTLB available

Conflicts:
arch/arm/include/asm/dma-mapping.h
drivers/xen/swiotlb-xen.c
[Conflicts arose b/c "arm: make SWIOTLB available" v8 was in Stefano's
branch, while I had v9 + Ack from Russel. I also fixed up white-space
issues]
