cachestat is a new syscall that was previously wired in for most
architectures:

However, those patches miss arm64, which has its own syscall table in arch/arm64.
This patch wires cachestat in for arm64.

You may want to clarify that this is for compat support on arm64,
otherwise native support uses the generic syscall numbers already.

Thanks, I updated the changelog thusly.  Note that this patch is
transitory - it will be squashed into "cachestat: wire up cachestat for
other architectures".

It's my expectation too - it makes sense to squash it to the other patch.
Thanks, Andrew!
