From b42f7a1b305d370c71e4f358de942df97d6347df Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Thu, 22 Aug 2024 11:45:16 +0200 Subject: [PATCH] generic: 5.15, 6.1: enable CNP support Ever since CONFIG_ARM64_PAN was enabled Common Not Private (CNP) is now visible and kernel builds will stop as they are not set in kernel config for 5.15 and 6.1. So, lets enable Common Not Private (CNP) which is ARMv8.2 feature and will be NOP of CPU-s that dont support it.
