  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.
