("[PATCH v25 00/20] i386 cleanup PART 2")

This started out to address a fixme in Claudio's patch set, then
wandered a bit, with cleanups and bug fixes in the code that I was
touching.  I stopped when I reached my original goal of removing

There are a lot of patches, but hopefully they're all small
enough to be obvious.
