Will Deacon d5370f7548 arm64: prefetch: add alternative pattern for CPUs without a prefetcher ... Most CPUs have a hardware prefetcher which generally performs better without explicit prefetch instructions issued by software, however some CPUs (e.g. Cavium ThunderX) rely solely on explicit prefetch instructions. This patch adds an alternative pattern (ARM64_HAS_NO_HW_PREFETCH) to allow our library code to make use of explicit prefetch instructions during things like copy routines only when the CPU does not have the capability to perform the prefetching itself.
