Log Message:
Integration of many changes done by Matthias Pfaller with a few by me.

clock.c		* Removed definition of DELAY.

intr.c		* Removed an unneeded $Id:....$

locore.s	* Moved some of the low level initialization
		  code to machdep.c.
		* Defined proc_trampoline.
		* Changed sigcode to pass scp to SYS_sigreturn.
		* Changed copyin/copyout/fu*/su* to take advantage
		  of the ns32532's dual address instructions.
		* Recoded copyinstr/copyoutstr/copystr in assembler.
		* Added a new and faster version of bzero.
		  This makes bzero.s unnecessary.
		* Defined suswintr to make profiling work.
		* Recoded cpu_switch modelled after the i386
		  version of cpu_switch.
		* Added support for lazy fpu state restore to
		  cpu_switch.
		* Recoded trap handling code to be more readable.
		* Added experimental code for single cacheline
		  invalidation.

machdep.c	* Copied over cpu_startup from i386/i386/machdep.c.
		* Changed sys_sigreturn to take advantage of the
		  argument passed by the trampoline code.
		* Changed boot to call doshutdownhooks and to store
		  machine state in case of a panic.
		* Changed setregs to clear the fpu registers.
		* Recoded low_level_init. It's now called init532.
		* cpu_reset: New function, resets the machine.

trap.c		* Pulled over from i386/i386/trap.c.
		* Added support for lazy saved/restored fpu state.

vm_machdep.c	* Removed kstack double mapping by pulling over alot
		  of code from i386/i386/vm_machdep.c.
		* Added support for lazy saved/restored fpu state.
		* Moved freeing of process resources from cpu_wait
		  to cpu_exit.
		* Pulled over cpu_coredump, pagemove, vmapbuf and
		  vunmapbuf from i386/i386/vm_machdep.c.

pmap.c		* Pulled over from i386/i386/pmap.c.

genassym.c	* Removed old and unused definitions, added new ones.

sys_machdep.c	* Moved sys_sysarch from machdep.c to sys_machdep.c.

process_machdep.c	* Changed to work without ktack double mapping.
			* Changed to work with lazy saved/restored fpu state.
