To make it easier for module-init-tools and scripts like mkinitrd to
distinguish builtin and missing modules, install a modules.builtin file
listing all builtin modules. This is done by generating an additional
config file (tristate.conf) with tristate options set to uppercase 'Y'
or 'M'. If we source that config file, the builtin modules appear in
obj-Y.

The toplevel Makefile creates the directory if it runs silentoldconfig
automatically, but if run manually, it fails:
$ make mrproper
$ make defconfig && make silentoldconfig
*** Default configuration is based on 'x86_64_defconfig'
#
# configuration written to .config
#
scripts/kconfig/conf -s arch/x86/Kconfig
*** Error during update of the kernel configuration.
...
Move the mkdir command to the silentoldconfig target to make it work.

When the output directory is something other than the kernel source,
the streamline_config script gets confused. This patch passes in the
source directory to the script so that it can find the proper files.

zconf.y includes zconf.hash.c from the initial code section.
zconf.hash.c references the token constants from zconf.y. However,
current bison defines the token constants after the initial code
section, making zconf.hash.c fail to compile. Move the include of
zconf.hash.c later in zconf.y, so bison puts it after the token
constants.

When typeahead find is enabled, using 'y', 'n' and 'm' to change the status
of the configuration items will also start up the search system, making you
jump around the configuration.
Disabling the enable_search property does not mean that search is not
possible, it only disables the typeahead; to execute a search in the
treeview, you can just call it up explicitly (i.e.: on most systems that
will be Ctrl-f).

Sometimes when configuring need to disable some unused item, but the item is
selected by many other items, it's hard to find the real dependency which
selected it, This patch add every symbol's value accompanied to make it
possible to find the real dependency easily.
An example is CONFIG_RFKILL,
---------------------- RF switch subsystem support ----------------------
| CONFIG_RFKILL: |
| |
| Say Y here if you want to have control over RF switches |
| found on many WiFi and Bluetooth cards. |
| |
| To compile this driver as a module, choose M here: the |
| module will be called rfkill. |
| |
| Symbol: RFKILL [=m] |
| Prompt: RF switch subsystem support |
| Defined at net/rfkill/Kconfig:4 |
| Depends on: NET [=y] |
| Location: |
| -> Networking support (NET [=y]) |
| Selected by: IWLCORE [=n] && NETDEVICES [=y] && !S390 [=S390] && PC |

There's a dependency missing.
$ make localyesconfig
HOSTCC scripts/basic/fixdep
HOSTCC scripts/basic/docproc
HOSTCC scripts/basic/hash
using config: '/boot/config-2.6.27.25-78.2.56.fc9.x86_64'
/bin/sh: line 8: scripts/kconfig/conf: No such file or directory
make[1]: *** [localyesconfig] Error 127
make: *** [localyesconfig] Error 2
Thus the script failed to run. But the sed command that converts the '=m'
to '=y' still ran. This gives us a distro config with all modules
converted to built in!
The missing dependency was for conf for localyesconfig. This
dependency was already set for localmodconfig.

If one were to run localmodconfig or localyesconfig without having
a .config already in the file, then the end of the process would give
a warning when it tries to move the old .config to .config.old.
This patch adds a test to check if .config exists and avoid the moves
if it does not.

As Andi Kleen pointed out, most people would expect that the local .config

Instead of using the .config in the local directory. This patch
changes streamline_config.pl to search various locations for a config.
Here's the list and order of search:
/proc/config.gz
/boot/vmlinuz-`uname -r`
vmlinux # local to the directory
/lib/modules/`uname -r`/kernel/kernel/configs.ko
kernel/configs.ko
kernel/configs.o
.config
Once it finds a file that contains a config (it checks if the binary
objects have configs first) it then uses it to create the .config
with minimum modules needed.

Ingo Molnar suggested that the streamline_config.pl should enable
CONFIG_IKCONFIG to keep the current config in the kernel.
Then we can use scripts/extract-ikconfig to find the current
modules.
This patch changes streamline_config.pl to check if CONFIG_IKCONFIG
is not set, and if it is not, it enables it to be a module.

The streamline_config.pl finds all the configs that are needed to
compile the currently loaded modules. After it creates the .config
file, it tests to make sure all the configs that are needed were
set.
It only looks at the configs that are modules, it does not look
at the builtin configs. This causes unnecessary warnings about modules
not being covered.

If a config does not have a prompt, it must be selected.
streamline_config.pl keeps track of all configs that select other configs.
If a config that does not have a prompt needs to be set to enable a
current module, it will include all configs that select it.
Note, streamline_config.pl does not enable modules that are not already
enabled. It only keeps enabled those that were enabled and might be
needed to compile the current modules.
The code to find the selects of a config is after the code that
adds the depends. But if a config needed selects but had no dependencies,
it would not be set. Because the code would stop before getting to
the select.
