Thanks applying into fixes.

I've dropped this last line as that's pretty obvious from the commit alone.
You can put extra comments like that could between some "---" lines:
---
This is based on -rc4...
---
So they get ignored when the patch gets applied. What is important,
is what it was tested on, so saying "Tested on ams delta" would be
more meaningful, although I guess that too is pretty obvious in this
case :)

Regards,

Tony
