After taking a second look at the patches, I want to get
these into 4.1. It will be nice to enable cross compile
as well in this release.

The one patch I won't be able to take it through kselftest
tree is kdbus for logistical reasons. kdbus is going through
Greg's tree - one of his many trees :)

Greg!

Will you be able to include this kdbus patch in this series
in your pull request for kdbus. I will reply to the kdbus
patch in this series and cc you on that. If this doesn't
work, could you suggest an alternative.

thanks,
