Subject: linux-next: build failure after merge of the mm tree

Hi all,

After merging the mm tree, today's linux-next build (powerpc allnoconfig)
failed like this:

In file included from include/linux/suspend.h:5,
                 from arch/powerpc/mm/mem.c:17:
include/linux/swap.h:581:12: error: 'folio_alloc_swap' defined but not used [-Werror=unused-function]
  581 | static int folio_alloc_swap(struct folio *folio, gfp_t gfp_mask)
      |            ^~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

(and many, many more - some just warnings)

Caused by commit

  436a263c3c8e ("mm, swap: simplify folio swap allocation")

from the mm-unstable branch of the mm tree.

I have applied the following patch for today.
