alldefconfig create a configuration with all values set
to their default value (form the Kconfig files).
This may be useful when we try to use more sensible default
values and may also be used in combination with
the minimal defconfigs.

Consider following kconfig file:
config TEST1
bool "test 1"
depends on TEST2
config TEST2
bool "test 2"
depends on TEST1
Previously kconfig would report:
foo:6:error: found recursive dependency: TEST2 -> TEST1 -> TEST2
With the following patch kconfig reports:
foo:5:error: recursive dependency detected!
foo:5: symbol TEST2 depends on TEST1
foo:1: symbol TEST1 depends on TEST2
Note that we now report where the offending symbols are defined.
This can be a great help for complex situations involving
several files.
Patch is originally from Roman Zippel with a few adjustments by Sam.

When we add a new config symbol save the file/line
so we later can refer to their location.
The information is saved as a property to a config symbol
because we may have multiple definitions of the same symbol.
This has the side-effect that a symbol always has
at least one property.

Rename to a name that better match the other kconfig targets.
listnewconfig shall read as:
- list new options compared to current configuration
New options are now written to stdout so one can redirect the output.
Do not exit with an error code if there is new options.
These are feature changes compared to the original
nonint_oldconfig - but as this feature has not yet been in a
released kernel it should not matter.
It is still possible to do:
make listnewconfig
lookup new config options in Kconfig*
edit .config

The list of options supported by conf is growing
and their abbreviation did not resemble anything usefull.
So drop the single letter options in favour of long options.
The long options are named equal to what we know from
the make target.
The internal implmentation was changed to match this,
resulting in much more readable code.
Support for short options is dropped - no one is supposed
to call this program direct anyway.

There seems to be a kconfig bug due to MODULES not always being
evaluated if no .config is found. Take the following Kconfig as an
example:
config MODULES
def_bool y
config FOO
def_tristate m
With no .config, the following configuration is generated:
CONFIG_MODULES=y
CONFIG_FOO=y
With an empty .config, the following:
CONFIG_MODULES=y
CONFIG_FOO=m
Tristate choice statements can also exhibit the problem, due to having an
implicit rev_dep (select) containing "m".
The problem is that MODULES is never evaluted in conf_read_simple() unless
there's a .config. The following patch fixes this.

This makes it so "make oldconfig" really prompts for any choice where

The "select" statement in Kconfig files allows the enabling of options
even if they have unmet direct dependencies (i.e. "depends on" expands
to "no"). Currently, the "depends on" clauses are used in calculating
the visibility but they do not affect the reverse dependencies in any
way.
The patch introduces additional tracking of the "depends on" statements
and prints a warning on selecting an option if its direct dependencies
are not met.

Run:
make ARCH=arm menuconfig
And then select "System Type" -> "ARM system type". The kconfig
"choice" menu at this point looks empty.
It's because config ARCH_S3C2410 has a long prompt:
config ARCH_S3C2410
bool "Samsung S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443, S3C2450"
...
menuconfig centers the checklist according to this prompt without
considering the width of the list, and then things get wrong.

Those configs are not new:
$ cat .config
...
CONFIG_NAMESPACES=y
...
CONFIG_BLOCK=y
...
But are tagged as NEW:
$ yes "" | make config > myconf
$ cat myconf | grep '(NEW)'
Namespaces support (NAMESPACES) [Y/?] (NEW) y
...
Enable the block layer (BLOCK) [Y/?] (NEW) y
...
You can also notice this bug when using gconfig/xconfig.
It's because the SYMBOL_DEF_USER bit of an invisible symbol is cleared
when the config file is read:
int conf_read(const char *name)
{
...
for_all_symbols(i, sym) {
if (sym_has_value(sym) && !sym_is_choice_value(sym)) {
/* Reset values of generates values, so they'll appear
* as new, if they should become visible, but that
* doesn't quite work if the Kconfig and the saved
* configuration disagree.
*/
if (sym->visible == no && !conf_unsaved)
sym->flags &= ~SYMBOL_DEF_USER;
...
}
But a menu item which represents an invisible symbol is still
visible, if it's sub-menu is visible, so its SYMBOL_DEF_USER
bit should be set to indicate it's not NEW.

This patch has been around for a long time in Fedora and Red Hat Enterprise
Linux kernels and it may be useful for others. The nonint_oldconfig target
will fail and print the unset config options while loose_nonint_oldconfig will
simply let the config option unset. They're useful in distro kernel packages
where the config files are built using a combination of smaller config files.
Arjan van de Ven wrote the initial nonint_config and Roland McGrath added the
loose_nonint_oldconfig.

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.

A symbol's value won't be recalc-ed until we save config file or
enter the menu where the symbol sits.
So If I enable OPTIMIZE_FOR_SIZE, and search FUNCTION_GRAPH_TRACER:
Symbol: FUNCTION_GRAPH_TRACER [=y]
Prompt: Kernel Function Graph Tracer
Defined at kernel/trace/Kconfig:140
Depends on: ... [=y] && (!X86_32 [=y] || !CC_OPTIMIZE_FOR_SIZE [=y])

From the dependency it should result in FUNCTION_GRAPH_TRACER=n,
but it still shows FUNCTION_GRAPH_TRACER=y.

Minor perlcritic warning:
headerdep.pl: "return" statement with explicit "undef" at line 84, column 2. See page 199 of PBP. (Severity: 5)
The rationale according to PBP is that an explicit return of undef
(contrary to most people's expectations) doesn't
always evaluate as false. It has to with the fact that perl return value
depends on context the function is called. If function is used in
list context, the appropriate return value for false is an empty list;
whereas in scalar context the return value for false is undefined.
By just using a "return" both cases are handled.
In the context of a trivial script this doesn't matter. But one script
may be cut-paste into later code (most people like me only know 50%
of perl), that is why perlcritic always complains

Currently looking up a structure definition in TAGS / tags takes one to
one of multiple "static struct X" definitions in arch sources, which makes
it for many structs practically impossible to get to the required header.
This patch changes the order of sources being tagged to first scan
architecture includes, then the top-level include/ directory, and only
then the rest. It also takes into account, that many architectures have
more than one include directory, i.e., not only arch/$ARCH/include, but
also arch/$ARCH/mach-X/include etc.

2. -m MODULE_DIRNAME Specify the module directory name.
3. Change hex function to Math::BigInt->from_hex.
