Merge tag 'stable/for-linus-3.14-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull Xen bugfixes from Konrad Rzeszutek Wilk: "This has an healthy amount of code being removed - which we do not use anymore (the only user of it was ia64 Xen which had been removed already). The other bug-fixes are to make Xen ARM be able to use the new event channel mechanism and proper export of header files to user-space. Summary: - Fix ARM and Xen FIFO not working. - Remove more Xen ia64 vestigates. - Fix UAPI missing Xen files" * tag 'stable/for-linus-3.14-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: ia64/xen: Remove Xen support for ia64 even more xen: install xen/gntdev.h and xen/gntalloc.h xen/events: bind all new interdomain events to VCPU0
