(There is plenty of uint.._t in Linux.)

I assume you're referring specifically to the privcmd structure change,
which is the only Linux-specific part of the patch. The privcmd
structure is shared between userspace and the kernel. Since "u64" is a
kernel type, we need to use "uint64_t", which has meaning in userspace.
