+Subject: [PATCHv2 5/7] treewide: Rename HOSTLDFLAGS to KBUILD_HOSTLDFLAGS
+To: Masahiro Yamada <yamada.masahiro@socionext.com>
+To: Josh Poimboeuf <jpoimboe@redhat.com>
+To: Jiri Olsa <jolsa@kernel.org>
+Cc: linux-kbuild@vger.kernel.org
+Cc: linux-kernel@vger.kernel.org
+Cc: Robin Jarry <robin.jarry@6wind.com>
+
+In preparation for enabling command line LDFLAGS, re-name HOSTLDFLAGS to
+KBUILD_HOSTLDFLAGS as the internal use only flags. This should not have any
+visible effects.
