Subject: linux-next: manual merge of the kbuild tree with the origin tree

Hi all,

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

  scripts/Makefile.modfinal

between commit:

  dc1f85a9637cc ("kallsyms: extend lineinfo to loadable modules")

from the origin tree and commit:

  7abef41afad05 ("kbuild/btf: Remove broken module relinking exclusion")

from the kbuild 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.
