Checkpatch sometimes has false positives. This makes it less useful for automatic usage: tools like b4 [0] can run checkpatch on all of your patches and give you a quick overview. When iterating on a branch, it's tiresome to manually re-check that any errors are known false positives. This patch adds a feature to record in the patch "graveyard" (after the "---" that a patch might produce a certain checkpatch error, and that this is an expected false positive. Note, for Git users this will require some configuration changes to adopt (see documentation patch), and not all tools that wrap Checkpatch will automatically be able to take advantage. Changes are required for `b4 prep --check` to work [0], I'll send that separately if this patch is accepted.
