From e4f7a7260737a040d43c64c0eb1421daeb83f583 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 31 May 2020 17:47:06 +0900 Subject: [PATCH] kbuild: force to build vmlinux if CONFIG_MODVERSION=y commit 4b50c8c4eaf06a825d1c005c0b1b4a8307087b83 upstream. This code does not work as stated in the comment. $(CONFIG_MODVERSIONS) is always empty because it is expanded before include/config/auto.conf is included. Hence, 'make modules' with CONFIG_MODVERSION=y cannot record the version CRCs. This has been broken since 2003, commit ("kbuild: Enable modules to be build using the "make dir/" syntax").
