Merge branch 'akpm' (Andrew's patch-bomb)

Merge misc patches from Andrew Morton:
 "The MM tree is rather stuck while I wait to find out what the heck is
  happening with sched/numa.  Probably I'll need to route around all the
  code which was added to -next, sigh.

  So this is "everything else", or at least most of it - other small
  bits are still awaiting resolutions of various kinds."

* emailed patches from Andrew Morton <akpm@linux-foundation.org>: (180 commits)
  lib/decompress.c add __init to decompress_method and data
  kernel/resource.c: fix stack overflow in __reserve_region_with_split()
  omfs: convert to use beXX_add_cpu()
  taskstats: cgroupstats_user_cmd() may leak on error
  aoe: update aoe-internal version number to 50
  aoe: update documentation to better reflect aoe-plus-udev usage
  aoe: remove unused code
  aoe: make dynamic block minor numbers the default
  aoe: update and specify AoE address guards and error messages
  aoe: retain static block device numbers for backwards compatibility
  aoe: support more AoE addresses with dynamic block device minor numbers
  aoe: update documentation with new URL and VM settings reference
  aoe: update copyright year in touched files
  aoe: update internal version number to 49
  aoe: remove unused code and add cosmetic improvements
  aoe: increase net_device reference count while using it
  aoe: associate frames with the AoE storage target
  aoe: disallow unsupported AoE minor addresses
  aoe: do revalidation steps in order
  aoe: failover remote interface based on aoe_deadsecs parameter
