Update of /home/smp/sys/i386/include
In directory freefall.freebsd.org:/tmp/cvs-serv4705/i386/include

Modified Files:
	mpasm.h smp.h 
Added Files:
	apic.h 
Log Message:
Round #1 of some cleanups I've been tinkering with for a while but never
got around to finishing.  Also made it compile and link again after the
recent -current update.  I'd bet money that this does not yet boot, I've not
even tested it yet, this is just a checkpoint in case I fall asleep and
Poul-Henning wants to have a go.. :-)

Notable changes:
 - locore.s is now very close to -current, with only minor #ifdef SMP
   parts.
 - the APIC is no longer mapped Virtual == Physical, because this required
   tweaking of the PTD's and other nightmares.  It now is dereferenced
   via a pointer (unsigned int *apic_base;)
 - the APIC register defines redone to cope with this.  Now are offsets
   instead of absolute addresses.  This means that the boot code needs to
   manually compensate when it's making a physical reference before paging
   is set up.  It also means that _get_mplock cannot be used before paging
   is enabled.
 - pmap.c sets up the apic mapping in rather than locore.  A lot of the other
   apic initialisation could be done in C too rather than mpcore.s/locore.s

I resisted the temptation to hack out the serial_putc() stuff, as I've a
feeling I'm going to need it... :-(

I'll say it again: THIS HAS NOT EVEN BEEN TESTED! IT PROBABLY DOES NOT YET
WORK.. :-)
