I've cut the compiler output. Removing the asm-generic doesn't show this
problem, but so far I fail to see the reason...
Thanks for trying this.
Do you have the kernel config file, I can try to reproduce on my local
machine. And by the way, it could be fixed with below patch, not very
sure. Earlier, Arnd suggested this to fix a similar case.
already tried it, but it doesn't fix the issue. I've attached the
config.
I had attempted a similar approach before as Baoquan did, but met the
same build issue as Thomas that was not immediately clear to me why it
popped up. I would be curious to see how this can be resolved.
