Some kernel code-of-conduct refinements

Greg Kroah-Hartman has posted a series of
patches making some changes around the newly adopted code of conduct.
In particular, it adds a new
document describing how the code is to be interpreted in the kernel
community. 'I originally sent the first two patches in this series to a lot of
kernel developers privately, to get their review and comments and see if
they wanted to ack them. This is the traditional way we have always
done for policy documents or other 'contentious' issues like the GPLv3
statement or the 'closed kernel modules are bad' statement. Due to the
very unexpected way that the original Code of Conduct file was added to
the tree, a number of developers asked if this series could also be
posted publicly before they were merged, and so, here they are.'
