+Subject: kbuild: clear LDFLAGS in the top Makefile
+
+From: Masahiro Yamada <yamada.masahiro@socionext.com>
+
+commit ce99d0bf312daf0178e640da9e3c93b773a67e7d upstream.
+
+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.
