32# We are using a recursive build, so we need to do a little thinking
33# to get the ordering right.
34#
35# Most importantly: sub-Makefiles should only ever modify files in
36# their own directory. If in some directory we have a dependency on
37# a file in another dir (which doesn't happen often, but it's often
38# unavoidable when linking the built-in.o targets which finally
39# turn into vmlinux), we will call a sub make in that other dir, and
40# after that we are sure that everything which is in that other dir
41# is now up to date.
42#
43# The only cases where we need to modify files which have global
44# effects are thus separated out and done before the recursive
45# descending is started. They are now explicitly listed as the
46# prepare rule.
