9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros 
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".

too.)

c7c817b91a 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.

3e8850eab2 Enable CR0_AM on 486s. (We already handled the fault.) This would be more 
useful if it applied to the kernel.

level protection fault.

8476bee7b5 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.)

da79b43eae Move the existing frame pointer calculation into a separate helper function.
