In the previous threads about this the concept of kernel-only and shared
user and kernel headers has been seen as a good solution.
So a split in a kernel-only part, and another kernel+user part seems more
worth-while. And less error-prone.

Maybe something like:
mqueue.h	for kernel-only
mqueue_abi.h	for kernel+user
