I had it there originally, I guess I should have left it there ;-)
When I changed it, I was considering to do the same for additional
syscalls that have very small differences now (timer_create,
rt_sigqueueinfo, rt_sigpending, recvmsg, sendmsg) and use
in_compat_syscall() there, but then I decided against that.
In the end, I did like the split, as I found the smaller three
patches that contain the real change easier to review, and
it turns the larger patch at the end into a more obvious
transformation.
