Ok

A prefix should really be the name of a company or institution, so it could
be "arm" or "linux", but not "numa". Would could use "numa-associativity"
with a dash instead of a comma, but that would still be somewhat imprecise
because the associativity property is about system topology inside of
a NUMA domain as well, such as cores, core clusters or SMT threads that
only share caches but not physical memory addresses.
