As far as I can see related patches found in linux-next tree were not 
sent to linuxppc-dev at lists.ozlabs.org.

Could you resend them, and split out the introduction of 
CONFIG_ARCH_SUPPORTS_INT128 from other parts of patch "crypto: 
powerpc/poly1305 - Add SIMD fallback" and add the lib/tishift.S in the 
patch which adds CONFIG_ARCH_SUPPORTS_INT128 ?

Thanks
