As the person who introduced the gef_* PPC defconfigs to the kernel (I
understood this to be best practice), I'm happy to go along with
whatever - as long as I can build a bootable kernel from the mainline
kernel. 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
