The folio conversion patch only changed one of the two implementations,
the empty stub one still needs the corresponding change:

mm/memory-failure.c: In function '__get_hwpoison_page':
mm/memory-failure.c:1335:15: error: implicit declaration of function 'get_hwpoison_hugetlb_folio'; did you mean 'get_hwpoison_huge_page'? [-Werror=implicit-function-declaration]
 1335 |         ret = get_hwpoison_hugetlb_folio(folio, &hugetlb, false);
      |               ^~~~~~~~~~~~~~~~~~~~~~~~~~
      |               get_hwpoison_huge_page

Fixes: 92e109a2c5a7 ("mm/hugetlb: convert get_hwpoison_huge_page() to folios")

Hello,

I also posted a v3 of this patch with the build fix here: 
https://lore.kernel.org/linux-mm/20230119011057.91349-1-sidhartha.kumar@oracle.com/T/#u

I'm fine with either picking up this patch as a fix or picking up v3.

Thanks,
Sidhartha Kumar
