SVN rev 215414 on 2010-11-16 22:44:58Z by jkim
Invalidate TLBs explicitly. r1.4 of sys/i386/i386/i686_mem.c removed this
code but probably it only worked by chance because modifying CR4.PGE bit
causes invlidation of entire TLBs. Since these are very rare events, this
micro-optimization seems useless.
