This is a fix^3 for the mempool poisoning patch, which introduces a compile-time error on some ARM randconfig builds:
mm/mempool.c: In function 'check_element': mm/mempool.c:65:16: error: implicit declaration of function 'kmap_atomic' [-Werror=implicit-function-declaration] void *addr = kmap_atomic((struct page *)element); The problem is clearly the missing declaration, and including linux/highmem.h fixes it.
