From f949286c668aed5aa24acdb5838be9cfd9513bd3 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Wed, 4 Dec 2019 16:54:32 -0800 Subject: mm: remove __ARCH_HAS_4LEVEL_HACK and include/asm-generic/4level-fixup.h There are no architectures that use include/asm-generic/4level-fixup.h therefore it can be removed along with __ARCH_HAS_4LEVEL_HACK define.
