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"
