Subject: [Suggestion] arch: s390: mm: the warnings with allmodconfig and "EXTRA_CFLAGS=-W"

Hello Maintainers:

When allmodconfig for " IBM zSeries model z800 and z900"

It will report the related warnings ("EXTRA_CFLAGS=-W"):
  mm/slub.c:1875:1: warning: ‘deactivate_slab’ uses dynamic stack allocation [enabled by default]
  mm/slub.c:1941:1: warning: ‘unfreeze_partials.isra.32’ uses dynamic stack allocation [enabled by default]
  mm/slub.c:2575:1: warning: ‘__slab_free’ uses dynamic stack allocation [enabled by default]
  mm/slub.c:1582:1: warning: ‘get_partial_node.isra.34’ uses dynamic stack allocation [enabled by default]
  mm/slub.c:2311:1: warning: ‘__slab_alloc.constprop.42’ uses dynamic stack allocation [enabled by default]

Is it OK ?


Thanks.
