This is the same patch I submitted earlier (see v2 here [1], based on
Palmer's feedback). Palmer stated that the "S" extension should not be
exposed to usermode.

Since two people arrived at the same solution, I wonder if the
supervisor mode should really be hidden from userspace, as it's about
the CPU information, not about the environment the calling code is
running as.
