Modified files:
sys/i386/i386 pmap.c
Log:
Disabled the optimization of not doing an invltlb_1pg() when changing
pte's from zero. The TLB is supposed to be invalidated when pte's are
changed _to_ zero, but this doesn't occur in all cases for global pages
(PG_G stops invltlb() from working, and invltlb_1pg() is not used
enough).
