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
