From: Randy Dunlap <rdunlap@infradead.org>
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);
