| # *DOCUMENTATION* |
| # To see a list of typical targets execute "make help" |
| # More info can be located in ./README |
| # Comments in this file are targeted only to the developer, do not |
| # expect to learn how to build the kernel reading this file. |
| |
| # Do not print "Entering directory ..." |
| 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 of |
| # 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. |
