I think you meant to use `modifiers` and `count` here :P
If you really want to leave them out (because they're not used yet?),
you might want to add a note in the commit message.
(I know, you replace this code in the next patch, but I think commits
should also make sense on their own. Otherwise, why have two commits?)
Aside from this and my other nit-picks, the series is
Reviewed-by: Eric Engestrom <eric.engest...@imgtec.com>
up to patch #11 (the rest is too intel-specific for me, I'm afraid).
Cheers,
