Part 1: the essential part of this seems to be the trim_bios_range()
change, and that part is not too big. In v4, Yinghai also removed
probe_roms_32.c. That sounds like the right thing to do, but I'd
rather have that in separate patch so it doesn't obfuscate the other
change, and I don't know whether it *has* to be done for .34; maybe
it could be deferred.

Part 2: IMHO, we're putting way too much crap in kernel/resource.c.
A name like "reserve_region_with_split_check_child()" is a pretty
good clue that we've lost our way somewhere. But that's mostly a
cosmetic thing, and the end result does seem to be something that
fixes the current regression.

So I guess that in spite of my issues with the implementation, I'm
still OK with the concept.
