+Subject: [PATCH 1001/1002] Makefile: add prepare target for external modules
+
+We need to ensure that native versions of programs like `objtool` are
+built before trying to build out-of-tree modules, or else the build
+will fail.
+
+Unlike other distributions, we cannot include these programs in our
+kernel-devel archive, because we rely on cross-compilation: these are
+"host" programs and may not match the architecture of the target.
+
+Ideally, out-of-tree builds would run `make prepare` first, so that
+these programs could be compiled in the normal fashion. We ship all
+the files needed for this to work. However, this requirement is
+specific to our use case, and DKMS does not support it.
+
+Adding a minimal prepare target to the dependency graph causes the
+programs to be built automatically and improves compatibility with
+existing solutions.

+ external module builds"
+
+This reverts commit 1bb0b18a06dceee1fdc32161a72e28eab6f011c4 in which
+the targets to build "tools/*" were hidden for external modules, but
+they are required by the kmod kit since the 'tools/*' binaries are not
+distributed as part of the archive.
