Merge branch 'lookup-permissions-cleanup'

Browse Source 
* lookup-permissions-cleanup:
  jffs2/jfs/xfs: switch over to 'check_acl' rather than 'permission()'
  ext[234]: move over to 'check_acl' permission model
  shmfs: use 'check_acl' instead of 'permission'
  Make 'check_acl()' a first-class filesystem op
  Simplify exec_permission_lite(), part 3
  Simplify exec_permission_lite() further
  Simplify exec_permission_lite() logic
  Do not call 'ima_path_check()' for each path component
