[Oleg Nesterov]

Ingo, please pull from

  git://git.kernel.org/pub/scm/linux/kernel/git/oleg/misc uprobes/core

This fixes the serious bug, a forked process crashes if it returns
from the probed function called by its parent, this cc's stable.

Also the minor fix from Ralf.

Oleg Nesterov (6):
      uprobes: Change the callsite of uprobe_copy_process()
      uprobes: Introduce __create_xol_area()
      uprobes: Teach __create_xol_area() to accept the predefined vaddr
      uprobes: Change uprobe_copy_process() to dup return_instances
      uprobes: Change uprobe_copy_process() to dup xol_area
      uprobes: Teach uprobe_copy_process() to handle CLONE_VFORK

Ralf Baechle (1):
      uprobes: Remove the wrong __weak attribute
