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.
