Hi Jacek,
The question 3 was simply for the location of your code; i.e., creating another 1st-level subdirectory in kernel source tree seemed inappropriate. Like other "tools" such as "get-maintainer", "check-patch", ... , it seems that your code belongs to "tools/abi-checker". For later upstreaming, it seemed tools/* is appropriate.
For "Documentation" entry, you can start push what you already have. You can later make it more concrete.
Cheers,
MyungJoo.

In my last patch on tizen.org I added sample external module to show how to
use tools.
Of course I will add some additional documentation to present more details.

Regarding to your next two questions. My original plan was to use up a lot
of available
functionality/mechanisms from the kernel. Therefore I used Module.symvers
file as basic
source to get information about all exported kernel symbols and their
version (CRC).
I needed simple tool that performs operations like:
- Compare Module.symvers files for two different kernel version
- Compare kernel Module.symvers with similar file for kernel module
- Extract from external module all kernel symbols use be the module and
creates output file in format compatible with Module.symvers file.
I didn't find tool that meet my needs therefore I decided to develop own.
Most of operations performed by the tools are not depend on target
architecture (text Module.symvers files testing).
Regarding to module symbols extraction I use libelf to read ELF files.
I tested the tool on x86 and it works fine.
