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

Hi all,

After merging the block tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

io_uring/memmap.c: In function 'io_region_allocate_pages':
io_uring/memmap.c:173:24: error: implicit declaration of function 'alloc_pages_bulk_array_node'; did you mean 'alloc_pages_bulk_node'? [-Wimplicit-function-declaration]
  173 |         nr_allocated = alloc_pages_bulk_array_node(gfp, NUMA_NO_NODE,
      |                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~
      |                        alloc_pages_bulk_node

Caused by commit

  1e21df691ffa ("io_uring/memmap: implement kernel allocated regions")

interacting with commit

  4f6a90a13f78 ("mm: alloc_pages_bulk: rename API")

from the mm-unstable branch of the mm tree.

I have applied the following merge fix up patch.
