You write beneficial for userspace - but don't add <asm/syscall.h> to
include/asm-generic/Kbuild.asm. Fortunately. I doubt there is any good
reason for userspace to know about kernel prototypes. For configurations
where userspace and kernel API differ - think 32-bit code running on a
64-bit kernel or similar - that would be a receipe for disaster.
