 - checkpatch

 - autofs

 - ipc

 - a ton of misc other things

* emailed patches from Andrew Morton <akpm@linux-foundation.org>: (100 commits)
  mm: split gfp_mask and mapping flags into separate fields
  fs: use mapping_set_error instead of opencoded set_bit
  treewide: remove redundant #include <linux/kconfig.h>
  hung_task: allow hung_task_panic when hung_task_warnings is 0
  kthread: add kerneldoc for kthread_create()
  kthread: better support freezable kthread workers
  kthread: allow to modify delayed kthread work
  kthread: allow to cancel kthread work
  kthread: initial support for delayed kthread work
  kthread: detect when a kthread work is used by more workers
  kthread: add kthread_destroy_worker()
  kthread: add kthread_create_worker*()
  kthread: allow to call __kthread_create_on_node() with va_list args
  kthread/smpboot: do not park in kthread_create_on_cpu()
  kthread: kthread worker API cleanup
  kthread: rename probe_kthread_data() to kthread_probe_data()
  scripts/tags.sh: enable code completion in VIM
  mm: kmemleak: avoid using __va() on addresses that don't have a lowmem mapping
  kdump, vmcoreinfo: report memory sections virtual addresses
  ipc/sem.c: add cond_resched in exit_sme
