Merge branch 'drivers-net-warning-clean'

Jesse Brandeburg says:

====================
make drivers/net/ethernet W=1 clean

The Goal: move to W=1 being default for drivers/net/ethernet, and
then use automation to catch more code issues (warnings) being
introduced.
The status: Getting much closer but not quite done for all
architectures.

After applying the patches below, the drivers/net/ethernet
directory can be built as modules with W=1 with no warnings (so
far on x64_64 arch only!). As Jakub pointed out, there is much
more work to do to clean up C=1, but that will be another series
of changes.

This series removes 1,247 warnings and hopefully allows the
ethernet directory to move forward from here without more
warnings being added. There is only one objtool warning now.

This version drops one of the Intel patches, as I couldn't
reproduce the original issue to document the warning.

Some of these patches are already sent and tested on Intel Wired
Lan, but the rest of the series titled drivers/net/ethernet
affects other drivers. The changes are all pretty
straightforward.
