Some kernel code-of-conduct refinements

Greg Kroah-Hartman has posted a series ofpatches making some changes around the newly adopted code of conduct.In particular, it adds a newdocument describing how the code is to be interpreted in the kernelcommunity. "I originally sent the first two patches in this series to a lot ofkernel developers privately, to get their review and comments and see ifthey wanted to ack them. This is the traditional way we have alwaysdone for policy documents or other 'contentious' issues like the GPLv3statement or the 'closed kernel modules are bad' statement. Due to thevery unexpected way that the original Code of Conduct file was added tothe tree, a number of developers asked if this series could also beposted publicly before they were merged, and so, here they are."
