Is a page fault across NUMA nodes "major" or "minor"?

I understand that on a single-socket Linux system, a command such as sudo ps -eo min_flt,maj_flt,cmd will generally count a page fault as "minor" if it blocks on a memory-to-memory copy, or on the zeroing of a deallocated page, or for some reason doesn't touch persistent storage. But is this true on NUMA systems as well, even when the fault requires a data transfer from one NUMA node to another? Or does that cross the line into "major"?
