    Subject[PATCH 0/6] kconfig: add support to show hidden options which have prompts
    (in menuconfig)
    Press <Z> to show all config symbols which have prompts.

    Quote Tim Bird (

    | I've been bitten by this numerous times. I most often
    | use ftrace on ARM, but when I go back to x86, I almost
    | always go through a sequence of searching for the
    | function graph tracer in the menus, then realizing it's
    | completely missing until I disable CC_OPTIMIZE_FOR_SIZE.
    | Is there any way to have the menu item appear, but be
    | unsettable unless the SIZE option is disabled? I'm
    | not a Kconfig guru...

    I myself found this useful too. For example, I need to test
    ftrace/tracing and want to be sure all the tracing features are
    enabled, so I enter the "Tracers" menu, and press <Z> to
    see if there is any config hidden.

    I noticed gconfig and xconfig have a button "Show all options",
    but that's a bit too much, and I think normally what we are not
    interested in those configs which have no prompt thus can't be
    changed by users.


    --- Tracers
    -*- Kernel Function Tracer
    - - Kernel Function Graph Tracer
    [*] Interrupts-off Latency Tracer
    - - Preemption-off Latency Tracer
    [*] Sysprof Tracer

    Here you can see 2 tracers are not selectable, and then can find
    out how to make them selectable.

    I also add this support for gconfig, but haven't done for xconfig.

    btw: are there many users using gconfig/xconfig today ?
