Hardware with MCA bus is limited to 386 and 486 class machines
that are now 20+ years old and typically with less than 32MB
of memory.  A quick search on the internet, and you see that
even the MCA hobbyist/enthusiast community has lost interest
in the early 2000 era and never really even moved ahead from
the 2.4 kernels to the 2.6 series.

This deletes anything remaining related to CONFIG_MCA from core
kernel code and from the x86 architecture.  There is no point in
carrying this any further into the future.

One complication to watch for is inadvertently scooping up
stuff relating to machine check, since there is overlap in
the TLA name space (e.g. arch/x86/boot/mca.c).

    menuconfig: let make not report error when not save configuration

Pressing ESC should cancel the yes/no dialog and return back to

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.

This patch was inspired by the kernel projects page, where an ncurses
replacement for menuconfig was mentioned (by Sam Ravnborg).

Building on menuconfig, this patch implements a more modern look
interface using ncurses and ncurses' satellite libraries (menu, panel,
form). The implementation does not depend on lxdialog, which is
currently distributed with the kernel.

Help text for certain config options is very extensive (the text
includes the names of all  other options the option in question depends
on). Long lines are not wrapped, making it impossible to see the list
without scrolling horizontally.

This patch adds some logic which wraps help screen lines at word
boundaries to prevent truncating.

Tested by running

  ARCH=powerpc make menuconfig O=/tmp/build

which shows that the long lines are now wrapped, and

 ARCH=powerpc make xconfig O=/tmp/build

to demonstrate that it still compiles and operates as expected.

Kconfig is powerfull tool. So powerfull that more and more software
projects are using it for configuration. So instead of fixing some of
them one by one, lets fix it in kernel and wait for sync.

This work was originaly done for PTXdist - GPL licensed build system for
userlands and cross-compilers, but it will not hurt kernel kconfig
either. PTXdist menuconfig now works on Windows linked with PDCurses and
compiled using MinGW - there is no termios and signals.

* Do not include <sys/wait.h> and <signal.h> (comes from times when
  lxdialog was separate process)
* Do not mess with termios directly and let curses tell screen size.
  Comment to commit c8dc68ad says
  check for screen size could be removed later, but because it didn't
  happen for more than year I left it here as well.

menuconfig currently represents options implied by another option ('select'
directive in Kconfig) by prefixing them with '---'.  Unfortunately the same
notation is used for comments.  If the implied option is module capable,
user can still switch between Y and M, all without any feedback until she
visits option's help.  (try saying M to MAC80211 and then toggling
CFG80211)

This patch changes notation of selected-by-another items by introducing 2
new representations for implied options: {*} or {M} for options selected by
another modularized one, thus builtin or module capable, -*- or -M- for
options that cannot be at the moment changed by user.

The idea is to represent actual capability of the option by braces (dashes)
around and to always report actual state by * or M inside.

Run "make xconfig" on a freshly untarred kernel-tree.  Look at the floppy disk
icon of the qt application, that has just started: Its in a normal, active
state.

Mouse click on it: .config is being saved.

This patch series changes things so taht
after the mouse click on the floppy disk icon, the icon is greyed out.
If you mouse click on it now, nothing happens.

If you change some CONFIG_*, the floppy disk icon returns to "active state",
that is, if you mouse click it now, .config is written.

This patch:

Returns sym_change_count to reflect the .config's change state.
All read only accesses of
	sym_change_count
are replaced by calls to
	conf_get_changed()
.
mconfig.c is manipulated to ask for saving only when
conf_get_changed() returned true.

<ESC><ESC> is used to step one back in the dialogs.
When lxdialog became built-in pressing <ESC> once would cause one step back
and pressing <ESC><ESC> would cause two steps back.
This patch - based on concept from Roman Zippel <zippel@linux-m68k.org> -
makes one <ESC> a noop and pressing <ESC><ESC> will cause one step backward.

In addition the final yes/no dialog now has the option to go back to the
the kernel configuration. So if you get too far out you can now go back
to configuring the kernel without saving and starting all over again.

It is loosly based om previous work by:  Petr Baudis <pasky@ucw.cz>

Following is a list of changes:
o Moved build of dialog routings to kconfig Makefile
o menubox + checklist uses a new item list to hold all menu items
o in util.c implmented helper function to deal with item list
o menubox now uses parameters to save scroll state (avoids temp file)
o textbox now get text to be displayed as parameter and not a file
o make sure to properly delete subwin's before main windows
o killed unused files: lxdialog.c msgbox.c
o modified return value for ESC to match direct calling
o in a few places the code has been adjusted to 80 char wide
o in textbox a small refactoring was made to make code remotely readable
o in mconf removed all unused stuff (functions/variables)

Following is a list of know short comings:
a) pressing ESC twice will be interpreted as two ESC presses
b) resize does not work. menuconfig needs to be restarted to be adjusted
