Subject: [PATCH 1/4] kbuild: remove ARCH_POSTLINK from module builds
Date:   Tue, 17 Oct 2023 19:37:39 +0900
Message-Id: <20231017103742.130927-1-masahiroy@kernel.org>

Precedence: bulk

The '%.ko' rule in arch/*/Makefile.postlink does nothing but call the
'true' command.

Remove the meaningless code.
