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

Hi all,

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

  arch/x86/include/asm/thread_info.h

between commit:

  e9ea1e7f53b8 ("x86/arch_prctl: Add ARCH_[GET|SET]_CPUID")

from the tip tree and commit:

  afb94c9e0b41 ("livepatch/x86: add TIF_PATCH_PENDING thread flag")

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,
