The confusion is that we have PPC_FEATURE_HAS_ALTIVEC, but that doesn't mean we have *these* VMX instructions. This is actually an arch/powerpc patch, so I'll merge it unless Herbert objects. cheers -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH] crypto: crc32c-vpmsum - Convert to CPU feature based module autoloading
From: Anton BlanchardThis patch utilises the GENERIC_CPU_AUTOPROBE infrastructure to automatically load the crc32c-vpmsum module if the CPU supports it.
