Subject: [PATCH] kbuild: warn if always, hostprogs-y, or hostprogs-m is used
Date:   Tue, 28 Apr 2020 01:03:57 +0900
Message-Id: <20200427160357.253085-1-masahiroy@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

always, hostprogs-y, and hostprogs-m are deprecated.

There is no user in upstream code, but I am keeping them for external
modules. I want to remove them entirely someday. Notify the deprecation
to downstream users.
