If CONFIG_TRIM_UNUSED_KSYMS is enabled and the kernel is built from a pristine state, the vmlinux is linked twice. Commit 3fdc7d3fe4c0 ("kbuild: link vmlinux only once for CONFIG_TRIM_UNUSED_KSYMS") explains why this happens, but it did not fix the issue at all. Now I realized I had applied a wrong patch. In v1 patch [1], the autoksyms_recursive target correctly recurses to "$(MAKE) -f $(srctree)/Makefile autoksyms_recursive". In v2 patch [2], I accidentally dropped the diff line, and it recurses to "$(MAKE) -f $(srctree)/Makefile vmlinux". Restore the code I intended in v1.
