This patch enables SSE2 memset for AMD's upcoming Orochi processor. This patch also fixes the following bug: For misaligned blocks larger than > 144 Bytes, memset branches into the integer code path depending on the value of misalignment even if the startup code chooses the SSE2 code path upfront, when multiarch is enabled.
