cf83d9e090 lip service to making ISA support machine-independent. This is the first 
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.

3a7bbb1acd lip service to making ISA support machine-independent. This is the first 
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.  eventually (when other ports with ISA
busses really start using this code), more 'high-level' ISA support will
live here.

1da06c0ed6 Machine dependant stuff has been moved to <machine/cdefs.h>. 1995-01-19 01:54:52 +00:00
jtc
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".

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.
