  "message": "mm: convert mm-\u003ecpu_vm_cpumask into cpumask_var_t\n\ncpumask_t is very big struct and cpu_vm_mask is placed wrong position.\nIt might lead to reduce cache hit ratio.\n\nThis patch has two change.\n1) Move the place of cpumask into last of mm_struct. Because usually cpumask\n   is accessed only front bits when the system has cpu-hotplug capability\n2) Convert cpu_vm_mask into cpumask_var_t. It may help to reduce memory\n   footprint if cpumask_size() will use nr_cpumask_bits properly in future.\n\nIn addition, this patch change the name of cpu_vm_mask with cpu_vm_mask_var.\nIt may help to detect out of tree cpu_vm_mask users.\n\nThis patch has no functional change.\n\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Koichi Yasutake \u003cyasutake.koichi@jp.panasonic.com\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
