        src/sys/arch/i386/i386 [netbsd-2-0]: pmap.c

Log Message:
Pull up revision 1.172 (requested by yamt in ticket #138):
- keep cr3 register and its copy in TSS synchronized.
  otherwise an interrupt vector using a task gate (ie. ddbipi) messes it up.
- defer LDTR loading as well as cr3.
- tweak comments to make three copies of switching code more synchronized.
