-# *DOCUMENTATION*
-# To see a list of typical targets execute "make help"

-# Comments in this file are targeted only to the developer, do not
-# expect to learn how to build the kernel reading this file.
-

-MAKEFLAGS += --no-print-directory
-
-# 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.
-
-# To put more focus on warnings, be less verbose as default
