Something is wonky.  That symbol is (/ really ought to be) in the
hypercall page and most definitely not inline.

Which tree is that changeset from?  I can't find the SHA.

I hate to open a separate can of worms, but why are they tagged GPL? 
The Xen hypercall ABI, like the Linux syscall ABI, are specifically not
GPL.  Xen has as something very similar to (and probably derived from)
the Linux-syscall-note exception.
