Andrew, I'm wondering if "make clean" would help...

I'm not lying, it works here. :-/

I've done these steps, 1:1, copy-pasted, assuming that
git26 is Linus' tree.

So, I have:

No, previously I did "make", i.e. "all" target. It's should be exactly
vmlinux and modules.. But now, I just copy-pasted your steps, and done
exactly what you've done. No errors.

No no. There is no "battery" branch, only "master" and "linus".
Default is "master", and "linus" is just clean Linus' tree. So
everything is correct.

Nice, thanks!
