Pull Xen ARM bugfix from Stefano Stabellini: "The patches fix the "xen_add_mach_to_phys_entry: cannot add" bug that has been affecting xen on arm and arm64 guests since 3.16. They require a few hypervisor side changes that just went in xen-unstable. A couple of days ago David sent out a pull request with a few other Xen fixes (it is already in master). Sorry we didn't synchronized better among us" * tag 'stable/for-linus-3.17-b-rc4-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/arm: remove mach_to_phys rbtree xen/arm: reimplement xen_dma_unmap_page & friends xen/arm: introduce XENFEAT_grant_map_identity
