From ed7588d5dc6f5e7202fb9bbeb14d94706ba225d7 Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Fri, 18 May 2018 13:35:24 +0300 Subject: x86/mm: Stop pretending pgtable_l5_enabled is a variable pgtable_l5_enabled is defined using cpu_feature_enabled() but we refer to it as a variable. This is misleading. Make pgtable_l5_enabled() a function. We cannot literally define it as a function due to circular dependencies between header files. Function-alike macros is close enough.
