Pull up revision 1.77 (requested by wrstuden in ticket #322):
Fix recent bugs seen on Performa 4400 macppc's by
Makoto Fujiwara <makoto%ki.nu@localhost> and Manuel Bouyer <bouyer%netbsd.org@localhost>.
Help from Allen Briggs, Jason Thorpe, and Matt Thomas.
We need to call cpu_cache_probe() early in boot (machdep.c).
Add 603 info for completeness, and use NBPG not PAGESIZE, as the
latter relies on uvm being setup (cpu_subr.c).
Let uvm_page_recolor() be called before uvm has been set up; just
note the page coloring value (uvm_page.c).
