Subject: kernel floating point simulation crash, postscript printer Makefile update
Index:	sys/pdp/mch_fpsim.s,local/mp/Makefile 2.11BSD

Description:
	The in kernel floating point emulator, used when no hardware FP unit
	is present, would panic the system on the first FP instruction
	executed by a user program.

Repeat-By:
	Try to run a program using FP on a system w/o hardware FP
Fix:
	Apply the patch below and rebuild the kernel.

	Also included in the patch is an update to the 'mp' Makefile.  This
	had been completed several years ago but never posted.
