Thanks, Dan. I appreciate the clarify on what you are looking for.

Sounds like if I go that route it's going to take some time.  I'm
thinking that if I do this I should deal with one ioctl cleanup per
series instead of aiming for the goal of getting compat to work.

What's your opinion of building the compat_ioctl function on top of the
existing code?  Using the internal compat functions to build a 64 bit
version of the data on the user mode stack? With that approach none of
the existing code would need to be touched although the end result
wouldn't be as nice or maintainable.
