I see your argument, but I was just going on the side of consistency because we're continuing to expose other features as HWCAPs when the capability is just a proxy for the cpuid field. I was in favour of stopping the addition of such HWCAPs years ago, but I couldn't convince Catalin ;)quoted

The way I see it, we'll soon run out of HWCAP2 bits and then we'll have our hand forced.quoted
I don't have a strong opinion either way.Me either, or at least not enough to object to doing it - Will? Catalin?
Until the ifunc resolver can work with CPUID, I think we should keep adding HWCAPn bits. We can revisit this with the toolchain people before introducing HWCAP3. -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
