Instead of having a pre-filled array xen_irq_ops for Xen PV paravirt
functions, drop the array and assign each element individually.
Same comment for the next few patches; this changelog is a little light
on *why*. I mean, I don't mind the change, but supposedly we should
justify things at least a little, right? :-)
Would you be fine with the following addition:
This is in preparation of reducing the paravirt include hell by
splitting paravirt.h into multiple more fine grained header files,
which will in turn require to split up the pv_ops vector as well.
Dropping the pre-filled array makes life easier for objtool to
detect missing initializers in multiple pv_ops_ arrays.
