Fwiw the manual I have on hand is just for the kernel API, so I couldn't
say.  On a quick flip-through, the sections appear to have been
rearranged (.e.g Section I describes datatypes used by syscalls) and in
none of the sections did I spot anything particularly resembling
userland applications, although I think the API documentation includes
non-syscall entrypoints implying parts of a userland C library.
