From b219545e9646e9d4089a74029c82ae59645e12ae Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Mon, 9 Nov 2015 09:55:45 +0100 Subject: [PATCH] arm64: fix STRICT_MM_TYPECHECKS issue in PTE_CONT manipulation The new page table code that manipulates the PTE_CONT flags does so in a way that is inconsistent with STRICT_MM_TYPECHECKS. Fix it by using the correct combination of __pgprot() and pgprot_val().
