Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace

Pull namespace updates from Eric Biederman:
 "This is a set of small fixes that were mostly stumbled over during
  more significant development. This proc fix and the fix to
  posix-timers are the most significant of the lot.

  There is a lot of good development going on but unfortunately it
  didn't quite make the merge window"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
  proc: Fix unbalanced hard link numbers
  signal: Make kill_proc_info static
  rlimit: Properly call security_task_setrlimit
  signal: Remove unused definition of sig_user_definied
  ia64: Remove unused IA64_TASK_SIGHAND_OFFSET and IA64_SIGHAND_SIGLOCK_OFFSET
  ipc: Remove unused declaration of recompute_msgmni
  posix-timers: Correct sanity check in posix_cpu_nsleep
  sysctl: Remove dead register_sysctl_root
