Fine with me, however the list is getting long. It would be better if
we could depend on a functional symbol rather than a negated list of
architectures. Would it make sense to have CONFIG_CPU_LITTLE_ENDIAN
defined on all little-endian architectures, so that driver can depend
on that if needed?

Yes, that idea pops up once in a while.

BTW, these days little endian PPC is also supported by Linux...

Alternatively, it might make more sense to list the architectures where
these drivers are actually used in practice. I guess that's X86, maybe
ARM and IA64, and that's all?

|| COMPILE_TEST ....

OK, thanks, what all of you said sounds reasonable to me.

Hello Geert:

Could you help send the related patch for it?


Thanks.
