Switch them to use the static_call() mechanism instead of pvops, as
this allows quite some simplification of the pvops implementation.
Due to include hell this requires to split out the time interfaces
into a new header file.
I guess you can add Peter's patch to your set, no?

With a slight modification, yes. :-)
