menuconfig: add support to show hidden options which have prompts
Usage: 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 also 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. Exmaple: --- 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.
