The HMAT messages printed at boot, beyond being noisy, can also print details for nodes that are not yet enabled. The primary method to consume HMAT details is via sysfs, and the sysfs interface gates what is emitted by whether the node is online or not. Hide the messages by default by moving them from "info" to "debug" log level. Otherwise, these prints are just a pretty-print way to dump the ACPI HMAT table. It has always been the case that post-analysis was required for these messages to map proximity-domains to Linux NUMA nodes, and as Priya points out that analysis also needs to consider whether the proximity domain is marked "enabled" in the SRAT.
