Hi all,

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

Caused by commit

  d389a4a81155 ("mm: Add folio flag manipulation functions")

interacting with commit

  eac96c3efdb5 ("mm: filemap: check if THP has hwpoisoned subpage for PMD page fault")

from Linus' tree.

I have applied the following merge fix patch taken from Andrew's patch
series.

From: Andrew Morton <[email-masked]>
Subject: mm-filemap-check-if-thp-has-hwpoisoned-subpage-for-pmd-page-fault-vs-folios

fix
mm-filemap-check-if-thp-has-hwpoisoned-subpage-for-pmd-page-fault.patch
for folio tree PAGEFLAG_FALSE() change.
