    jump_label: move 'asm goto' support test to Kconfig · e9666d10
    Masahiro Yamada authored
    Currently, CONFIG_JUMP_LABEL just means "I _want_ to use jump label".
    
    The jump label is controlled by HAVE_JUMP_LABEL, which is defined
    like this:
    
      #if defined(CC_HAVE_ASM_GOTO) && defined(CONFIG_JUMP_LABEL)
      # define HAVE_JUMP_LABEL
      #endif
    
    We can improve this by testing 'asm goto' support in Kconfig, then
    make JUMP_LABEL depend on CC_HAS_ASM_GOTO.
    
    Ugly #ifdef HAVE_JUMP_LABEL will go away, and CONFIG_JUMP_LABEL will
    match to the real kernel capability.
