Pull up following revision(s) (requested by tsutsui in ticket #869):
sys/arch/pmax/pmax/machdep.c: revision 1.233
Fix an #ifdef botch in rev 1.214 that causes
[ Kernel symbol table invalid! ] message at boot,
which means no ksyms(4) support even on GENERIC kernel.
Should be pulled up to netbsd-4 and netbsd-5.
