64# We are using a recursive build, so we need to do a little thinking
65# to get the ordering right.
66#
67# Most importantly: sub-Makefiles should only ever modify files in
68# their own directory. If in some directory we have a dependency on
69# a file in another dir (which doesn't happen often, but it's often
70# unavoidable when linking the built-in.o targets which finally
71# turn into vmlinux), we will call a sub make in that other dir, and
72# after that we are sure that everything which is in that other dir
73# is now up to date.
74#
75# The only cases where we need to modify files which have global
76# effects are thus separated out and done before the recursive
77# descending is started. They are now explicitly listed as the
78# prepare rule.
