Subject: linux-next: manual merge of the livepatching tree with the security
 tree

Hi Jiri,

Today's linux-next merge of the livepatching tree got conflicts in:

  include/linux/init_task.h
  include/linux/sched.h

between commit:

  e4e55b47ed9a ("LSM: Revive security_task_alloc() hook and per "struct task_struct" security blob.")

from the security tree and commit:

  d83a7cb375ee ("livepatch: change to a per-task consistency model")

from the livepatching tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
