Seems to do what it is missing from the tin :)

Fill the commit message and sprinkle more on the ioctl_wrappers.c?

Hmm, gcc doesn't allow pointer conversion between unsigned long long and
uint64_t?

Testing the waters. Looks sane but gcc doesn't like

igt_typecheck(unsigned long long, size);

and the kernel is using typedef unsigned long long __u64 not uint64_t.
A little bit of a conundrum.
