Hi all, After merging the mm-hotfixes tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: mm/ksm.c: In function 'ksm_might_need_to_copy': mm/ksm.c:2605:21: error: implicit declaration of function 'copy_mc_user_highpage'; did you mean 'copy_user_highpage'? [-Werror=implicit-function-declaration] 2605 | if (copy_mc_user_highpage(new_page, page, address, vma)) { | ^~~~~~~~~~~~~~~~~~~~~ | copy_user_highpage Caused by commit b7edf4b1cdb1 ("mm: hwpoison: support recovery from ksm_might_need_to_copy()") I have reverted that commit for today. -- Cheers, Stephen Rothwell
