Noah Goldstein 46b5e98ef6 x86: Add seperate non-temporal tunable for memset ... The tuning for non-temporal stores for memset vs memcpy is not always the same. This includes both the exact value and whether non-temporal stores are profitable at all for a given arch. This patch add `x86_memset_non_temporal_threshold`. Currently we disable non-temporal stores for non Intel vendors as the only benchmarks showing its benefit have been on Intel hardware. Reviewed-by: H.J.
