Subject: kconfig: split randconfig setup code into set_randconfig_seed()

This code is too big to be placed in the switch statement.

Move the code into a new helper function. I slightly refactor the code
without changing the behavior.

Subject: kconfig: refactor option parse code

The current option parse code is clumsy.

The 's' option is separately handled in an if-conditional due to the
following code:

    input_mode = (enum input_mode)opt;

If 's' is moved to the switch statement, the invalid value 's' would
be assigned to the input_mode.

Another potential problem is that we are mixing 'enum input_mode' and
ASCII characters. They could overwrap if we add more input modes.

To separate them out, set the flag field of long options to a pointer
of input_mode_opt. For mode select options, getopt_long() returns 0,
which never causes overwrap with ASCII characters that represent short
options.

Subject: kconfig: change defconfig_list option to environment variable

"defconfig_list" is a weird option that defines a static symbol that
declares the list of base config files in case the .config does not
exist yet.

This is quite different from other normal symbols; we just abused the
"string" type and the "default" properties to list out the input files.
They must be fixed values since these are searched for and loaded in
the parse stage.

It is an ugly hack, and should not exist in the first place. Providing
this feature as an environment variable is a saner approach.

 scripts/kconfig/Makefile

This is a partial revert of commit 2a86f6612164 ("kbuild: use
KBUILD_DEFCONFIG as the fallback for DEFCONFIG_LIST").

Now that the reference to $(DEFCONFIG_LIST) was removed from
init/Kconfig, the default KBUILD_DEFCONFIG can go back home.

Subject: kconfig: do not use allnoconfig_y option

allnoconfig_y is an ugly hack that sets a symbol to 'y' by allnoconfig.

allnoconfig does not mean a minimal set of CONFIG options because a
bunch of prompts are hidden by 'if EMBEDDED' or 'if EXPERT', but I do
not like to hack Kconfig this way.

Use the pre-existing feature, KCONFIG_ALLCONFIG, to provide a one
liner config fragment. CONFIG_EMBEDDED=y is still forced when
allnoconfig is invoked as a part of tinyconfig.

No change in the .config file produced by 'make tinyconfig'.

The output of 'make allnoconfig' will be changed; we will get
CONFIG_EMBEDDED=n because allnoconfig literally sets all symbols to n.

Subject: kconfig: nconf: fix core dump when searching in empty menu

The following code in get_mext_match():

  index = (index + items_num) % items_num;

... makes the program crash when items_num is zero (that is, the menu
is empty).

A menu can be empty when all the options in it are hidden by unmet
'depends on'.

For example,

  menu "This menu will be empty"

  config FOO
         bool "foo"
         depends on BROKEN

  endmenu

If you visit this menu and press a '/' key and then another key, nconf
crashes with:

  Floating point exception (core dumped)

When the number of items is zero, it does not make sense to search in
the menu. In this case, current_item() returns NULL, and item_index()
ERR, but get_mext_match() does not check it.

Let's make get_mext_match() just return if the menu is empty.

While I am here, change items_num from 'int' to 'unsigned int' because
it should never become negative.

sym_change_count has no good reason to be 'int' type.

sym_set_change_count() compares the old and new values after casting
both of them to (bool). I do not see any practical diffrence between
sym_set_change_count(1) and sym_add_change_count(1).

Use the boolean flag, conf_changed.

Subject: kconfig: use /boot/config-* etc. as DEFCONFIG_LIST only for native
 build

When the .config file is missing, 'make config', 'make menuconfig', etc.
uses a file listed in DEFCONFIG_LIST, if found, as base configuration.

Ususally, /boot/config-$(uname -r) exists, and is used as default.

However, when you are cross-compiling the kernel, it does not make
sense to use /boot/config-* on the build host. It should default to
arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG).

UML previously did not use DEFCONFIG_LIST at all, but it should be
able to use arch/um/configs/$(KBUILD_DEFCONFIG) as a base config file.

Subject: kconfig: mconf,nconf: remove unneeded '\0' termination after
 snprintf()

snprintf() always terminates the destination buffer with '\0' even if
the buffer is not long enough. (In this case, the last element of the
buffer becomes '\0'.)

The explicit termination is unneeded.

Subject: kconfig: nconf: get rid of (void) casts from wattrset() calls

This reverts commit 10175ba65fde ("nconfig: Silence unused return values
from wattrset").

With this patch applied, recent GCC versions can cleanly build nconf
without "value computed is not used" warnings.

The wattrset() used to be implemented as a macro, like this:

  #define wattrset(win,at) \
          (NCURSES_OK_ADDR(win) \
            ? ((win)->_attrs = NCURSES_CAST(attr_t, at), \
               OK) \
            : ERR)

The GCC bugzilla [1] reported a false-positive -Wunused-value warning
in a similar test case. It was fixed by GCC 4.4.1.

Let's revert that commit, and see if somebody will claim the issue.

Subject: kconfig: nconf: remove unneeded default for menu prompt

The rootmenu always has a prompt even if the 'mainmenu' statement is
missing in the top Kconfig file.

conf_parse() calls menu_add_prompt(P_MENU, "Main menu", NULL) in this
case.

So, every 'menu' has a prompt.

is set to values outside the range of the attribute_t enum.

At least,

  attributes_t attributes[ATTR_MAX+1] = {0};

... should be

  int attribute[ATTR_MAX+1] = {0};

Also, there is no need to hard-code the color-pair numbers in
attributes_t.

The current code is messy. Rewrite it.

Subject: kconfig: nconf: refactor in print_in_middle()

This helper is the same as the sample code in the NCURSES HOWTO [1],
but it is over-engineering to be used for nconf.

I do not see any good reason to use the 'float' type just for the
division by 2.

All the call-sites pass a non-NULL pointer to the first argument,
so 'if (win == NULL) win = stdscr;' is dead code.

'if (startx != 0) x = startx;' is dead code because 'x' will be
overridden some lines below, by 'x = startx + (int)temp;'.

All the call-sites pass a non-zero value to the second argument,
so 'if (starty != 0)' is always true.

getyx(win, y, x) is also dead-code because both 'y' and 'x' are
overridden.

All the call-sites pass 0 to the third parameter, so 'startx' can
be removed.

All the call-sites pass a non-zero value to the fourth parameter,
so 'if (width == 0) width = 80;' is dead code.

The window will be refreshed later, so there is no need to call
refresh() in this function.

Change the type of the last parameter from 'chtype' to 'int' to be
aligned with the prototype, 'int wattrset(WINDOW *win, int attrs);'

I also slightly cleaned up the indentation style.

Subject: kconfig: nconf: stop endless search loops

If the user selects the very first entry in a page and performs a
search-up operation, or selects the very last entry in a page and
performs a search-down operation that will not succeed (e.g., via
[/]asdfzzz[Up Arrow]), nconf will never terminate searching the page.

The reason is that in this case, the starting point will be set to -1
or n, which is then translated into (n - 1) (i.e., the last entry of
the page) or 0 (i.e., the first entry of the page) and finally the
search begins. This continues to work fine until the index reaches 0 or
(n - 1), at which point it will be decremented to -1 or incremented to
n, but not checked against the starting point right away. Instead, it's
wrapped around to the bottom or top again, after which the starting
point check occurs... and naturally fails.

My original implementation added another check for -1 before wrapping
the running index variable around, but Masahiro Yamada pointed out that
the actual issue is that the comparison point (starting point) exceeds
bounds (i.e., the [0,n-1] interval) in the first place and that,
instead, the starting point should be fixed.

This has the welcome side-effect of also fixing the case where the
starting point was n while searching down, which also lead to an
infinite loop.

OTOH, this code is now essentially all his work.

Amazingly, nobody seems to have been hit by this for 11 years - or at
the very least nobody bothered to debug and fix this.

Subject: kconfig: highlight gconfig 'comment' lines with '***'

Mark Kconfig "comment" lines with "*** <commentstring> ***"
so that it is clear that these lines are comments and not some
kconfig item that cannot be modified.

This is helpful in some menus to be able to provide a menu
"sub-heading" for groups of similar config items.

This also makes the comments be presented in a way that is
similar to menuconfig and nconfig.

Replace '*conf-cfg' with '[gmnq]conf-cfg' to make it explicit, and
