This change does not "fix a problem that causes a build error
(but not for things marked CONFIG_BROKEN), an oops, a hang, data
corruption, a real security issue, or some “oh, that’s not good” issue.
In short, something critical.". Only the first patch meets this criteria
and only that patch should be Cc:ed to stable@ .

Please remove from this patch.

Looks like you should remove the tags from pr_err and use pr_fmt(fmt) to
put tags on the messages:

#define pr_fmt(fmt) "kgdboc: " fmt
