Currently LDFLAGS is not cleared, so same flags are accumulated in LDFLAGS when the top Makefile is recursively invoked. I found unneeded rebuild for ARCH=arm64 when CONFIG_TRIM_UNUSED_KSYMS is enabled. If include/generated/autoksyms.h is updated, the top Makefile is recursively invoked, then arch/arm64/Makefile adds one more '-maarch64linux'. Due to the command line change, modules are rebuilt needlessly. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> --- Makefile | 1 + 1 file changed, 1 insertion(+)
