Same question here - will this need to be visible outside of the
file defining the variable? In the other patch as well as here,
if the answer is yes, the next question would be whether it needs
to be visible outside of xen/arch/x86/guest/hyperv/ (i.e. whether
it shouldn't live in a private header).
