└─> NVIDIA Carmel CNP: CNP on Carmel semantically different than ARM cores

In linux kernel since version 5.2 (release Date: 2019-07-07)  

If CNP is enabled on Carmel cores, non-sharable TLBIs on a core will not
invalidate shared TLB entries installed by a different core, as it would
on standard ARM cores.

If unsure, say Y.
