Subject: mm/mempolicy.c: fix mempolicy printing in numa_maps
From: David Rientjes <rientjes@xxxxxxxxxx>
commit 8790c71a18e5d2d93532ae250bcf5eddbba729cd upstream.
As a result of commit 5606e3877ad8 ("mm: numa: Migrate on reference
policy"), /proc/<pid>/numa_maps prints the mempolicy for any <pid> as
"prefer:N" for the local node, N, of the process reading the file.
This should only be printed when the mempolicy of <pid> is
MPOL_PREFERRED for node N.
If the process is actually only using the default mempolicy for local
node allocation, make sure "default" is printed as expected.
