You definitely need this function in xen_hypervisor.c, but I still
wonder if the for loop across callbacks in xen_driver.c is appropriate,
given that we are trying to get rid of the secondary callback structure,
or if we should just inline direct calls to the appropriate helper (I
brought up this same point in my review of 2/8). After all, not all
possible xen helpers implement the callback (for example, xen_inotify.c
does not).

That is, either we use the callback structure, and this function could
be private, or we declare this function and call it directly, then we
don't need an extra row in the secondary callback structure.

Spacing looks awkward here (space vs. tab).
You'll have tweaks to fold in a flag parameter, but overall this patch
looked sane.
ACK.
