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.

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.

Implement SA_SIGINFO for i386. Thanks to Bruce Evans for much more than a review, this was a nice puzzle. This is supposed to be binary and source compatible with older applications that access the old FreeBSD-style three arguments to a signal handler. Except those applications that access hidden signal handler arguments bejond the documented third one. If you have applications that do, please let me know so that we take the opportunity to provide the functionality they need in a documented manner. Also except application that use 'struct sigframe' directly. You need to recompile gdb and doscmd. `make world` is recommended. Example program that demonstrates how SA_SIGINFO and old-style FreeBSD handlers (with their three args) may be used in the same process is at http://www3.cons.org/tmp/fbsd-siginfo.c Programs that use the old FreeBSD-style three arguments are easy to change to SA_SIGINFO (although they don't need to, since the old style will still work): Old args to signal handler: void handler_sn(int sig, int code, struct sigcontext *scp) New args: void handler_si(int sig, siginfo_t *si, void *third) where: old:code == new:second->si_code old:scp == &(new:si->si_scp) /* Passed by value! */ The latter is also pointed to by new:third, but accessing via si->si_scp is preferred because it is type-save. FreeBSD implementation notes: - This is just the framework to make the interface POSIX compatible. For now, no additional functionality is provided. This is supposed to happen now, starting with floating point values. - We don't use 'sigcontext_t.si_value' for now (POSIX meant it for realtime-related values). - Documentation will be updated when new functionality is added and the exact arguments passed are determined. The comments in sys/signal.h are meant to be useful. Reviewed by: BDE
