ok - it's useful to point this out in the changelog. You can use the
"Impact:" header we started using recently:

Impact: cleanup, no functionality changed

See for example this upstream commit:

| commit 07454bfff151d2465ada809bbaddf3548cc1097c
| Author: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
| Date: Sat Oct 4 10:51:07 2008 +0200
|
| clockevents: check broadcast tick device not the clock events device
|
| Impact: jiffies increment too fast.

Mathieu, any objections against the patch?
