From 766ffb69803943c2b580a44ac14a189b875d21f6 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 28 Jul 2015 16:14:03 +0100 Subject: [PATCH] arm64: pgtable: fix definition of pte_valid pte_valid should check if the PTE_VALID bit (1 << 0) is set in the pte, so fix the macro definition to use bitwise & instead of logical &&.
