From d151e9719f184f00d0bb2af864d0aef9beaee7ab Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 17 Jan 2019 09:10:04 +0900 Subject: kbuild: merge KBUILD_VMLINUX_{INIT,MAIN} into KBUILD_VMLINUX_OBJS The top Makefile does not need to export KBUILD_VMLINUX_INIT and KBUILD_VMLINUX_MAIN separately. Put every built-in.a into KBUILD_VMLINUX_OBJS. The order of $(head-y), $(init-y), $(core-y), ... is still retained.
