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

Hi all,

After merging the mm-hotfixes tree, today's linux-next build (arm
allmodconfig) failed like this:

mm/vmscan.c:4090:9: error: implicit declaration of function ‘pmd_young’; did you mean ‘pte_young’? [-Werror=implicit-function-declaration]

Caused by commit

  3f85e711d5af ("mm: introduce arch_has_hw_nonleaf_pmd_young()")

This error was found by the kernel.ci bot and so is still int today's
tree.
