Thanks a lot for picking this up again and including my two patches!

I've done a private review yesterday, but will have another look either
today or tomorrow to see if I missed anything. I've also applied the
series to my randconfig build tree and will see if that finds any new
bugs. The builder has already found a bug in one of my two patches,
so there might be more.
