Janosch Frank 3afdfca698 s390/mm: Clear skeys for newly mapped huge guest pmds 
Similarly to the pte skey handling, where we set the storage key to
the default key for each newly mapped pte, we have to also do that for
huge pmds.

With the PG_arch_1 flag we keep track if the area has already been
cleared of its skeys.
