I've checked the docs once again, and, indeed, they don't mention Armv8.2, so I'll remove the reference. However, judging from cursory read of https://patchwork.kernel.org/patch/9275721/ , it appears only Armv8.2 kernels would set EXECUTE_ONLY bits on the pages, kernels for Armv8.[01] would set READ permissions on EXEC pages as well.
