Man the liferafts! Here comes the long awaited SMP -> -current merge! There are various options documented in i386/conf/LINT, there is more to come over the next few days. The kernel should run pretty much "as before" without the options to activate SMP mode. There are a handful of known "loose ends" that need to be fixed, but have been put off since the SMP kernel is in a moderately good condition at the moment. This commit is the result of the tinkering and testing over the last 14 months by many people. A special thanks to Steve Passe for implementing the APIC code! 1997-04-26 11:46:25 +00:00			`/*`

Preliminaries for stop_cpus()/restart_cpus(). Both are turned off by default. Added macro for displaying POST codes from kernel. 1997-06-27 23:12:31 +00:00			`* $Id: smptests.h,v 1.1 1997/06/26 18:02:47 smp Exp smp $`

Added a test called 'LATE_START'. This is now the default, it delays most of the MP startup to the function machdep.c:cpu_startup(). It should be possible to move the 2 functions found there (mp_start() & mp_announce()) even further down the path once we know exactly where that should be...
