Merge branch 'stable/xen-swiotlb-0.8.6' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
* 'stable/xen-swiotlb-0.8.6' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: x86: Detect whether we should use Xen SWIOTLB. pci-swiotlb-xen: Add glue code to setup dma_ops utilizing xen_swiotlb_* functions. swiotlb-xen: SWIOTLB library for Xen PV guest with PCI passthrough. xen/mmu: inhibit vmap aliases rather than trying to clear them out vmap: add flag to allow lazy unmap to be disabled at runtime xen: Add xen_create_contiguous_region xen: Rename the balloon lock xen: Allow unprivileged Xen domains to create iomap pages xen: use _PAGE_IOMAP in ioremap to do machine mappings Fix up trivial conflicts (adding both xen swiotlb and xen pci platform driver setup close to each other) in drivers/xen/{Kconfig,Makefile} and include/xen/xen-ops.h
