└─>Debug arch page table for semantics compliance
In linux kernel since version 5.1 (release Date: 2019-05-05)  
This option provides a debug method which can be used to test
architecture page table helper functions on various platforms in
verifying if they comply with expected generic MM semantics. This
will help architecture code in making sure that any changes or
new additions of these helpers still conform to expected
semantics of the generic MM. Platforms will have to opt in for

If unsure, say N.
