+Subject: [PATCHv2 7/7] Kbuild: Use HOST*FLAGS options from the command line
+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: Robin Jarry <robin.jarry@6wind.com>
+Cc: Jonathan Corbet <corbet@lwn.net>
+Cc: linux-doc@vger.kernel.org
+
+
+Now that we have the rename in place, reuse the HOST*FLAGS options as
+something that can be set from the command line and included with the
+rest of the flags.
