From a8874e7e8a8896f2b6c641f4b8e2473eafd35204 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Wed, 31 Oct 2018 12:11:48 +0100 Subject: mm: make the __PAGETABLE_PxD_FOLDED defines non-empty Change the currently empty defines for __PAGETABLE_PMD_FOLDED, __PAGETABLE_PUD_FOLDED and __PAGETABLE_P4D_FOLDED to return 1. This makes it possible to use __is_defined() to test if the preprocessor define exists. Acked-by: Kirill A.
