Merge branch 'linux-linaro-lsk-v4.4' into linux-linaro-lsk-v4.4-android
Conflicts:
in fs/proc/task_mmu.c:
looks like vma_get_anon_name() want have a name for anonymous
vma when there is no name used in vma. commit: 586278d78bf
The name show is after any other names, so it maybe covered.
but anyway, it just a show here.
