	syssrc/sys/arch/powerpc/include/mpc6xx: pmap.h
	syssrc/sys/arch/powerpc/mpc6xx: mpc6xx_machdep.c pmap.c
	syssrc/sys/arch/powerpc/powerpc: pmap.c trap.c trap_subr.S

Log Message:
Move pte_spill calls from trap_subr to trap().  Count the number of
"evictions" and avoide calling pmap_pte_spill if there are no evictions
for the current pmap.  Make the ISI execption use the default exception
code.  Remove lots of dead stuff from trap_subr.

Make olink use TAILQ instead of LIST and be sorted with evicted entries
first and resident entries last.  Make use of this knowledge to make
pmap_pte_spill do a fast exit.
