  Modified files:
    sys/vm               vm_pageout.c 
  Log:
      Be less conservative with a recently added KASSERT.  Certain edge
      cases with file fragments and read-write mmap's can lead to a situation
      where a VM page has odd dirty bits, e.g. 0xFC - due to being dirtied by
      an mmap and only the fragment (representing a non-page-aligned end of
      file) synced via a filesystem buffer.  A correct solution that
      guarentees consistent m->dirty for the file EOF case is being
      worked on.  In the mean time we can't be so conservative in the
      KASSERT.
