All: Remove patch kit headers, and add $Id$ This is mostly to align some more code with NetBSD. cpu.h: Remove the old function vs. include configuration stuff that was ifdefed out when we went to inline functions. Remove the define of resettodr that made it a nop, there is already a function that makes it a nop, no need to #define one. Remove the #defines of processor types, they are now defined in cputypes.h, #include that file. Add struct cpu_nameclass for support of cpu types. frame.h: include sys/signal.h, it will be needed in the future. put the sigframe structure here that was in machdep.c pcb.h: Add multiple inclusion protection. Add pcb_ldt and pcb_ldt_len to pcb structure, this is for the user mode ldt.

* from: @(#)frame.h 5.2 (Berkeley) 1/18/91
From: Jeffrey Hsu <hsu@soda.berkeley.edu> The following patch adds the addr argument to signal handlers. The kernel with the patch is no more and no less in compliance or in violation of POSIX and ANSI C than the kernel before the patch. The added functionality this addr argument provides is quite useful. It enables an entire class of algorithms which use mprotect to trace memory references. Beside garbage collectors, I have heard of this technique being applied to debuggers and profilers. The only benchmarking I've performed is using akcl to compile maxima: without the kernel patch, it takes 7 hours to compile maxima, while with stratified garbage collection, it only takes 50 minutes. Basically, I can't think of a reason not to add the addr argument and there is a compelling need for it. If you find the patch acceptable, please let me know so I can send my FreeBSD akcl config files to wfs for inclusion in the core akcl release. The old 386BSD config files there won't work on either NetBSD or FreeBSD.

Made all header files idempotent and moved incorrect common data from headers into a related source file. Added cons.h as first step towards moving i386/i386/cons.h to machine/cons.h where it belongs.
