OK, thanks (at least for me, it is a good news).

But when I choose allmodconfig, then "COMPILE_TEST=y". this may allow a
module to compile under the architectures which no related HW support.

When cause compiling issue (HW not support), it is not module's issue,
we can not 'fix' module by force, and it is not architecture's issue,
either.

So we have to look for who has duty for this issue. At least now, it
seems only 'asm-generic' can be qualified to play this unlucky role.


Thanks.
