Please don't mix updates to linux-headers/ with updates to other files. linux-headers/ should only by updated via the scripts/update-linux-headers.sh script, and then the whole update should be included in the patch, not only selected files. Thanks, Thomas

[I didn't check whether the code is already included in Linux.]
