Subject: mm: memory-failure: add stub for page_handle_poison()
Fix a build error when no HWPOISON kconfig symbols are set/enabled
by providing a stub function for 'page_handle_poison()'.
../mm/memory-failure.c: In function `__soft_offline_page':
../mm/memory-failure.c:1827:3: error: implicit declaration of function `page_handle_poison'; did you mean `page_init_poison'? [-Werror=implicit-function-declaration]
page_handle_poison(page, false, true);
