sigreturn() and ptrace() security violations will now trap. Deal with those
...
traps by looking at the instruction stream and the stack to see if it looks
like we're returning to user mode, and if so pop to the hooks in locore.s.
This will fail in the case where a pop %ds or pop %es faults when returning
from a fast interrupt, but this should not be possible.

useful if it applied to the kernel.

level protection fault.
