From: Jason Gunthorpe <jgg@xxxxxxxxxxxx>
The DECLARE_CMD macros can construct the proper wrapper structures using
the output from the preprocessing script to include the exact struct
content from the kernel headers as an anonymous tagless embedded struct.
This gives us one cannonical source of data for the kernel structures.
Some mild code edits are required due to needless differences between the
two headers.
