    kbuild: rename prepare to archprepare to fix dependency chain · 5bb78269
    Sam Ravnborg authored
    When introducing the generic asm-offsets.h support the dependency
    chain for the prepare targets was changed. All build scripts expecting
    include/asm/asm-offsets.h to be made when using the prepare target would broke.
    With the limited number of prepare targets left in arch Makefiles
    the trivial solution was to introduce a new arch specific target: archprepare
    The dependency chain looks like this now:
      +--> prepare0
             +--> archprepare
    		+--> scripts_basic
                    +--> prepare1
                           +---> prepare2
                                   +--> prepare3
    So prepare 3 is processed before prepare2 etc.
    This guaantees that the asm symlink, version.h, scripts_basic
    are all updated before archprepare is processed.
    prepare0 which build the asm-offsets.h file will need the
    actions performed by archprepare.
    The head target is now named prepare, because users scripts will most
    likely use that target, but prepare-all has been kept for compatibility.
    Updated Documentation/kbuild/makefiles.txt.
