I think this series is useful and we should merge it. Are there any
remaining dependencies or conflicts with Christoph Hellwig's recent
__ioremap rework? If there are, I would prioritize his work and maybe
delay this one by another merge window, otherwise please add
my Reviewed-by to all patches and resend them for Greg to pick
up (provided he has no objections).
