+
+# We are using a recursive build, so we need to do a little thinking
+# to get the ordering right.
+#
+# Most importantly: sub-Makefiles should only ever modify files in
+# their own directory. If in some directory we have a dependency on
+# a file in another dir (which doesn't happen often, but it's often
+# unavoidable when linking the built-in.o targets which finally
+# turn into vmlinux), we will call a sub make in that other dir, and
+# after that we are sure that everything which is in that other dir
+# is now up to date.
+#
+# The only cases where we need to modify files which have global
+# effects are thus separated out and done before the recursive
+# descending is started. They are now explicitly listed as the
+# prepare rule.
