The impact is limited only to the modules which would otherwise
potentially load on a HP system which advertizes as "HPE ", "Server ".

You're the only user of ghes_edac. So please state which drivers you
want blocked from loading on those platforms and where ghes_edac should
load instead.

it is 4 drivers.

The owner thing should not be touched now - it can be a cleanup ontop if
you - Justin - feel like doing it afterwards.

Thx.
