Add support for Intel's Supervisor Mode Access Prevention (SMAP) feature.
When enabled SMAP will generate page faults on the kernel attempting
to read/write user data pages unless an override flag is set.
Instructions that modify the flag are patched into copyin/copyout and
friends on boot if SMAP is enabled.
Those with access to hardware with SMAP can contact me for a test case.
