IOW, something like the attached patch.

It's not extensively tested, but hey, the diffstat looks nice:

  arch/arm64/include/asm/syscall_wrapper.h |  4 ---
  arch/riscv/include/asm/syscall_wrapper.h |  5 ----
  arch/s390/include/asm/syscall_wrapper.h  | 13 +--------
  arch/x86/include/asm/syscall_wrapper.h   | 34 +++---------------------
  kernel/sys_ni.c                          | 14 ++++++++++
  kernel/time/posix-stubs.c                | 45 --------------------------------
  6 files changed, 19 insertions(+), 96 deletions(-)

and it builds in at least a *couple* of configurations, including with
CONFIG_POSIX_TIMERS disabled.

I did *not* check whether it might fix the warning, since I doubt my
user space would even boot without that posix timer support (actually,
honestly, because I'm just lazy and "it _looks_ fine to me" was the
main real thing).

But that SYS_NI() thing really does deserve to die, as it was purely
used as a hack for some random timer system calls.

Comments?
