I think I understand Linus' wish not to see all the defconfig churn (I get fed up diffing defconfigs, just to read through loads of additions and removals of undef'ed entires from just the few configs I'm interested in). I assume I'm not alone among those attempting to add board support to the mainline kernel in not being able to keep up with the LKML mailing list and therefore have missed most of this discussion (think I've managed to read some of it now). I would very much appreciate some documentation / guidance on how to use this script - preferably provided as a comment in the head of the script or/and some pointers in "Documentation/".
