This would break the current table creation and management scheme, so
some reworking would have to be done anyway.  As for cleaning up struct
device_node, you're preaching to the choir.  How will the tables be
associated with devices in the new case?

User-space DLPAR stuff doesn't care about these tables, or at what point
they're freed, if that's what you mean.  Thanks for looking at the
patch, I'll take reluctant acceptance over nothing :)
