I've gone through the ACPI-related patches in this series (other than [2/20]
that I've commented directly) and while I haven't found anything horrible in
them, I don't quite feel confident enough to ACK them.

What I'm really missing in this series is a design document describing all that
from a high-level perspective and making it clear where all of the pieces go
and what their respective roles are.  Also reordering the series to introduce
the nd subsystem to start with and then its users might help here.
