Well, patch 1 & 2 are really unrelated fixes (I've only stumbled
across them when trying to install via CDROM from OVMF/DUET),
so it'd be fine with those.
Patch for is really only for debugging, so it's more a cleanup than
fixing a real issue.
Patch 5 is something I'm relying on for the later patches, so I'd
need to rework the patchset.
Nothing major, though; the later patches should work even with patch
5 pulled.

Cheers,

Hannes
