Section 4.1.2, second paragraph, this sentence:
"These CPU cores were clustered so that each had equal access time to a lock memory bank,"
"These CPU cores were clustered so that each had equal access time to a local memory bank,"
I think you're right, that there's not much point in the 22.214.171.124 section on the /sys filesystem entries. You're right that numctl uses /sys entries to figure out topology but there's probably no reason for us to have a section just on /sys. Maybe we should fold that into the numctl section?
Other than that it looks good.
