This no longer applied cleanly. Mostly there was fuzz near .of_match_table
changes as probe_new (and remove_new?) changes have been recently merged.
There were other issues as well, I marked a few patches in the set "not
applicable" as other patches had already done equivalent changes earlier.

There were substance-changing changes in the 20th patch, replied to the
disuccsion there.

I've pushed the result here and intend to send PR to Mauro soon if there
are no issues:
