I already said *no* to this.

If you want to log errors, implement a PMU or RAS driver that reports
errors on a per ITS basis, in a way that is collectable by existing
tooling.

The kernel log is not the place for your sorry debug hacks, which is
in general not readable by normal users. And I'd rather remove the
other instances as a matter of consistency.
