I applied all of this, it's a really nice patch set.  If there are any
problems we can deal with it using follow-on fixups.

I noticed something, in patch #3 where you remove the spurious wrap
bit setting in startup_gfar().  It looks like that was not only
spurious but it was doing it wrong too.

It's writing garbage into the status word, because it's not using the
BD_LFLAG() macro to shift the value up 16 bits.
