The change to move the pagealloc logic broke the slab allocator check when it's disabled at compile time: mm/slab.c: In function 'is_debug_pagealloc_cache': mm/slab.c:1608:29: error: implicit declaration of function 'debug_pagealloc_enabled' [-Werror=implicit-function-declaration] This adds an inline helper to get it to work again.
