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
