I'd be very happy to see the resulting tool in the kernel tree, as it
needs to be kept in sync with any significant changes done to the kernel
layout in the future.
It's not important if the result is based off libabigail or kabi-dw
code, I'm sure both can be adjusted to serve the needs. kabi-dw tends to
be smaller and still rather proof-of-concept, libabigail is definitely
more mature. The only real difference is C vs. C++ code.

Sounds great!
Thank you!
