[PATCH 7] kdb-cmd-mempolicy-extend

Change kdb mempolicy command to recognize local preferred policy.

Minor change to MPOL_PREFERRED policy output in kdbm_mpol():

  If the MPOL_F_LOCAL flag is set, then just output 'local'
  since the v.preferred_node field is not initialized/valid
  in this case, and this flag means to allocate memory on
  the local/current node, where ever that may be at the
  time of the fault.
