      kbuild: Split Makefile into needs / needs not .config · 77c83c75
      Kai Germaschewski authored
      The current top-level Makefile has a fundamental problem which
      makes "make oldconfig vmlinux" impossible:
      
      It includes .config, which is changed by "oldconfig". So after "oldconfig"
      .config has changed and the .config the Makefile had read is obsolete.
      make provides a mechanism to cope with this, it'll restart automatically 
      if any of the files it included changed, if you let it know that you
      changed it, just using a normal rule which has .config as its target.
      
      However, once you tell make that "make oldconfig" changes .config, you
      have another problem: oldconfig always uses .config to be remade, there's
      no mechanism to tell if it's up to date. So makes notices that .config
      has changed, restarts, makes oldconfig again, notices that .config has
      changed, restarts, ... you get the picture.
      
      The way to solve this is to do a proper two-stage approach: If you just
      say "make oldconfig", there's no need for the Makefile to even read the
      .config. If it does not, it won't restart and recurse infintely.
      So we divide the Makefile into two sections: One for targets which don't
      need the variables from .config, like *config, clean, mrproper and
      one section which does the actual build, which needs to know the
      CONFIG_ options.
      
      If one of the "noconfig" targets is given, we handle those, without
      reading .config. From there, we call make again, filtering out the already
      handled targets, to do the main work.
      
      The fact that this actually works correctly can be seen by trying
      "make vmlinux oldconfig" which will execute things in the right
      order - and this is not just nitpicking, it means that "-j" will
      get this case right, too.
      
      The $(CONFIGURATION) hack used to start "make config" automatically
      can go away now, too. Since we don't know which of make *config the
      user prefers, we'll just ask him call "make whatever-config" himself,
      instead of forcing "make config" on him.

      kbuild: Use consistently FORCE instead of dummy · cc4749dc
      Kai Germaschewski authored
      FORCE is the de-facto standard name for a prequisite to force
      recompilation, so instead of using a mix of 'dummy','FORCE' and
      'FORCE_RECOMPILE' use 'FORCE' everywhere.
      
      Also, move figuring out the path relative to the top level dir
      into Rules.make, instead of calling an external script.
