The default AllocatePrefetchDistance is 3 * the dcache line size.
http://hg.openjdk.java.net/jdk/jdk11/file/tip/src/hotspot/cpu/aarch64/vm_version_aarch64.cpp#l132
If the cache line size is 256, we trip over an error at
http://hg.openjdk.java.net/jdk/jdk11/file/tip/src/hotspot/share/runtime/flags/jvmFlagConstraintsCompiler.cpp#l93
This is because the prefetch distance is limited to 512.
