[PATCH 0/6] kconfig: add support to show hidden options which haveprompts

From: Li Zefan

Usage:
(in menuconfig)
Press <Z> to show all config symbols which have prompts.

Quote Tim Bird (http://lkml.org/lkml/2010/3/19/319):

| 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.

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.

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

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