I don't expect the arm64 guys will have any interesting in changing the
bitops in this way. So please can you fix this on the Xen side, perhaps
in the way I suggested.

If at some point arm64 does gain 32-bit capable bitops we can always
switch back to using them directly again.

In the meantime we need to get this Xen regression fixed before 3.15. If
you don't have time to work on this please let us know.

Ian.
