I think this is a case where the preparatory patch is sufficiently 
self-contained that it is reasonable to have is on master separately from 
others that depend on it.  (This is not a review or approval of the 
details of the specific patch.  And for some patches, even when they are 
reasonable to include on their own, the review of the design of the patch 
may depend on looking at the later patches in the series to see how much 
the design is forced by requirements that aren't obvious from the patch in 
isolation.)
