Merge tag 'stable/for-linus-3.17-b-rc4-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
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"
