There are arm64 cell phones; I suspect the workload on a cellphone is
different enough from a server workload that it should be tested as well.
The end results may indicate 64k pages are a win everywhere or they
may indicate a need for two arm64 flavours when we eventually target
Sorry, I can't recommend any benchmarks that would simulate the cellphone
