  Log:
  MFC revision 1.38
    The sparc64/sparc64/pmap.c implementations of pmap_remove(),
    pmap_protect(), and pmap_copy() have optimizations for regions
    larger than PMAP_TSB_THRESH (which works out to 16MB).  This
    caused a panic in tsb_foreach for kernel mappings, since
    pm->pm_tsb is NULL in that case.  This fix teaches tsb_foreach
    to use the kernel's tsb in that case.
