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.
