The below build failure when !CONFIG_MEMORY_FAILURE was reported for
v5.16 merge window:

The commit d389a4a81155 ("mm: Add folio flag manipulation functions")
changed the definition of PAGEFLAG macros, this caused the build failure
for HasHWPoisoned flag. The new flag was introduced by commit
eac96c3efdb5 ("mm: filemap: check if THP has hwpoisoned subpage for PMD
page fault") in v5.15-rc7. But the folio series pull request was
prepared before v5.15, so this new flag was missed.

Should probbaly cc Linus, and also note that Stephen noticed & fixed
this problem already.

I didn't know about it at the time I sent the pull request because it
hadn't been merged at that point.

Oh, yes, I forgot that fix. Anyway picking either one is fine to me.

It is fine. I really don't mean blame to you.

Oops. And both my "small" and "large" config have MEMORY_FAILURE and
TRANSPARENT_HUGEPAGE enabled, which seems to be why my build tests
didn't trigger the failure case.
Will fix up.
