And is present on arm/powerpc/mips/arc and possibly others. So what are we talking about again? If you care about the non-DT case, why don't you make a patch about how you could support Guenter's use case on the x86. His use case is not uncommon, believe it or not, and x86 would benefit from something this flexible. >> >> Guenter > > Sebastian Regards -- Pantelis-- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
