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.
