I assume the #1 goal is to add reduced HW support.  So another
option to speed up merging is to just go ahead and duplicate a
bunch of code e.g. in pc_virt.c acpi/reduced.c or in any other
file.
This way it might be easier to see what's common code and what isn't.
And I think offline Igor said he might prefer that way. Right Igor?
