Any idea what this is ^ ? I don't know if this is caused by me or you,
but I only seem to see it on subthreads you've replied to.
Dave,
Sorry about that, should have trimmed that. It looks like the mail server is unhappy
about email received via kvmarm list and I don't know why.

We have something local in cpufeature.c, sys_caps_initialised. May be we could
reuse it here ? With or without that change, FWIW.
I'll take a look at that. Inventing that here seemed a little ugly, and
this is all driven from the cpufreatures code anyway now which ensures a
certain ordering.
If I can reuse sys_caps_initialised for this, I will -- seems pointless
to reinvent it.
