Not sure who "we" is in this context. Especially dropping easy support for all smbus devices (which are often like this) would seem quite wrong to me. And for real ISA devices there tends to be a surprisingly large user base left for those. The config option Ingo proposed is a good idea though. Or they can just use 64bit which never defines CONFIG_ISA, but of course still has to support all the similar smbus drivers. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
