From: "Ben Dooks (Codethink)" <ben.dooks@xxxxxxxxxxxxxxx> Subject: mm/init-mm.c: include <linux/mman.h> for vm_committed_as_batch mm_init.c needs to include <linux/mman.h> for the definition of vm_committed_as_batch. Fixes the following sparse warning: mm/mm_init.c:141:5: warning: symbol 'vm_committed_as_batch' was not declared. Should it be static?
