Remove PSL_USERCLR, and add a PSL_USERSTATIC. Change the bit descriptions to
...
more closely match the 386 manual. (Probably the mnemonics should be changed,
too.)

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.

Enable CR0_AM on 486s. (We already handled the fault.) This would be more
...
useful if it applied to the kernel.
Avoid btrl when checking AST flag.
Add hooks to recover from errors during any INTRFASTEXIT and simulate a user-
level protection fault.

Do the eflags security check in a cheaper way. Just check that the privilege

level of the return cs is correct; don't check the other selectors. (Will
fault later if they are invalid.)

Move the existing frame pointer calculation into a separate helper function.

Eventually this should cause the child to be swapped in if necessary.

faster and usually false.
