  Modified files:
    sys/arm/arm          pmap.c swtch.S 
  Log:
  Write back affected pages in pmap_qremove() as well. This removes the need
  to change the DACR when switching to a kernel thread, thus making
  userland thread => kernel thread => same userland thread switch cheaper by
  totally avoiding data cache and TLB invalidation.
