5e115a7e04 - Define and use MAXCPU like the alpha and i386 instead of NCPUS. 
- Sort the sys/mutex.h include in mp_machdep.c into a closer to correct
  location.

c794ceb56a Implement write combining for crashdumps. This is useful when 
write caching is disabled on both SCSI and IDE disks where large
memory dumps could take up to an hour to complete.

Taking an i386 scsi based system with 512MB of ram and timing (in
seconds) how long it took to complete a dump, the following results
were obtained:

Before:				After:
	WCE           TIME		WCE           TIME

ec222a71d9 Cleanup comment in machine/param.h regarding mbuf-related sizes, and get rid 
of MCLOFSET, which does not appear to be used anywhere anymore, and if it is,
it probably shouldn't be.

1ebcad5720 This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will 
not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.
