With this removal, should those be updated as well? Right, but may-sync-config and need-compiler are not interchangeable due to the following code. ifneq ($(KBUILD_EXTMOD),) may-sync-config := endif I will keep both.

Now that vdso_install does not depend on any in-tree build artifact, it no longer invokes a compiler, making no-compiler-targets the same as no-sync-config-targets. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> --- Makefile | 13 +------------ 1 file changed, 1 insertion(+), 12 deletions(-)
