Subject: [PATCH 27/27] lib: packing: remove MODULE_LICENSE in non-modules

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

Is this a bug fix? Does it need a Fixes: tag? How is it supposed to be
merged? lib/packing.c is maintained by netdev, and I believe that netdev
maintainers would prefer netdev patches to be submitted separately.

Note that I was copied only on this patch, I haven't read the cover
letter if that exists.

As Vladimir said, if you repost just patches 13 and 27 of this series
to netdev - we can take them in right away.
