Three existing callbacks are: kmemcheck, mmiotrace, notifier. Two

so can't be unified with others. (And kmemcheck also has two different
call site BTW)
We want mmiotrace to be generic distro capable so the overhead when the
hook is not used is of concern.
Maybe we should generalize paravirt-ops patching in case if (x) f() is
deemed too expensive.
