0da1d4a0b9 x86: Add "make tinyconfig" to configure the tiniest possible kernel
Since commit 5d2acfc7b9 ("kconfig: make
allnoconfig disable options behind EMBEDDED and EXPERT") in 3.15-rc1,
"make allnoconfig" disables every possible config option.

However, a few configuration options (CC_OPTIMIZE_FOR_SIZE,
OPTIMIZE_INLINING) produce a smaller kernel when turned on, and a few
choices exist (compression, highmem, allocator) for which a non-default
option produces a smaller kernel.

Add a "tinyconfig" option, which starts from allnoconfig and then sets
these options to configure the tiniest possible kernel.  This provides a
better baseline for embedded systems or efforts to reduce kernel size.

3aaefce103 x86, platform, kconfig: move kvmconfig functionality to a helper
The new mergeconfig helper makes it easier to add other partial
configurations similar to kvmconfig.  Architecture-independent portions
of those partial configurations should go in
kernel/configs/${name}.config, and architecture-dependent portions
should go in arch/${arch}/configs/${name}.config.

Based on a patch by Luis R. Rodriguez <mcgrof@suse.com>.
Originally-Signed-off-by: Luis R. Rodriguez <mcgrof@suse.com>

Modified to make the helper name more general than just virtualization,
support architecture-dependent and architecture-independent partial
configurations, move the helper and kvmconfig to
scripts/kconfig/Makefile, and factor out more of the common file path.

5d2acfc7b9 kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT
"make allnoconfig" exists to ease testing of minimal configurations.
Documentation/SubmitChecklist includes a note to test with allnoconfig.
This helps catch missing dependencies on common-but-not-required
functionality, which might otherwise go unnoticed.

However, allnoconfig still leaves many symbols enabled, because they're
hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT.  For instance, allnoconfig
still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't
typically get build-tested with those disabled.

To address this, introduce a new Kconfig option "allnoconfig_y", used on
symbols which only exist to hide other symbols.  Set it on CONFIG_EMBEDDED
(which then selects CONFIG_EXPERT).  allnoconfig will then disable all the
symbols hidden behind those.

95edca5c52 localmodconfig: Add config depends by default settings
Currently localmodconfig will miss dependencies from the default option.
For example:

config FOO
	default y if BAR || ZOO

If FOO is needed for a module and is set to '=m', and so are BAR or ZOO,
localmodconfig will not see that BOO or ZOO are also needed for the foo
module, and will incorrectly disable them.

00d4f8fc2c xconfig: Fix the filename for GUI settings
Currently the qconf program invoked by 'make xconfig' stores GUI
settings in the file ~/.config/Unknown\ Organization.conf.  This name
is apparently generated by the QSettings class when no organisation
or application name are specified.

This is obviously not a sensible filename (nor does it seem sensible
that these QSettings parameters are optional!).  Pass the names
'kernel.org' and 'qconf', resuling in the filename
~/.config/kernel.org/qconf.conf.

503c823048 kconfig: fix bug in search results string: use strlen(gstr->s), not gstr->len
The struct gstr has a capacity that may differ from the actual string length.

However, a string manipulation in the function search_conf made the assumption
that it is the same, which led to messing up some search results, especially
when the content of the gstr in use had not yet reached at least 63 chars.

57540f1dea kconfig: adjust warning message for conflicting types
Each symbol must have exactly one type assigned. However, if a symbol happens
to have two different types assigned at runtime, a warning is printed and the
first type is preserved while the second type is being ignored.

The warning message says

type of <symbol name> redefined from <first type> to <second type>

which may be misleading as it may create the impression that the second type
replaces the first type.

This patch clarifies this by changing the warning to

ignoring type redefinition of <symbol name> from <first type> to <second type>

And it updates the layout of the example search result, i. e. moves down the
"Defined at" and "Depends on" lines and adds a symbol state ([=n]) to the
symbol in the "Selected by" line.

Furthermore, the help texts now should fit in 80 columns again when viewed
in mconf.

e062781397 kconfig: do not allow more than one symbol to have 'option modules'
Previously, it was possible to have more than one symbol with the
'option modules' attached to them, although only the last one would
in fact control tristates.

Since this does not make much sense, only allow at most one symbol to
control tristates.

Note: it is still possible to have more than one symbol that control
tristates, but indirectly:

    config MOD1
        bool "mod1"
        select MODULES
    config MOD2
        bool "mod2"
        select MODULES
    config MODULES
        bool
        option modules

6902dccfda kconfig: do not special-case 'MODULES' symbol
Currently, the 'MODULES' symbol is hard-coded to be the default symbol
that enables/disables tristates, if no other symbol was declared with
'option modules'.

While this used to be needed for the Linux kernel, we now have an
explicit 'option modules' attached to the 'MODULES' symbol (since
cset 11097a036), so we no longer need to special-case it in the
kconfig code.

Furthermore, kconfig is extensively used out of the Linux kernel, and
other projects may have another meaning for a symbol named 'MODULES'.

This patch changes the way we enable/disable tristates: if a symbol was
found with 'option modules' attached to it, then that symbol controls
enabling tristates. Otherwise, tristates are disabled, even if a symbol
named 'MODULES' exists.

04b19b773a kconfig: silence warning when parsing auto.conf when a symbol has changed type
When a symbol changes type from tristate to bool, and was previously set to
'm', a subsequent silentoldconfig would warn about inconsistency, such as:

    include/config/auto.conf:3014:warning: symbol value 'm' invalid for
    HOTPLUG_PCI_PCIE

Seen by Linus with the merge in aa8032b (sequence to reproduce by Michal):
    git checkout 1fe0135
    make mrproper
    make allmodconfig
    make silentoldconfig
    git checkout aa8032b
    make allmodconfig
    make silentoldconfig

Since HOTPLUG_PCI_PCIE changed from tristate to bool in aa8032b, it was
previously set to 'm' in auto.conf by the first allmodconfig+silentoldconfig,
but then was set to 'y' by the second allmodconfig. Then the second
silentoldconfig prints the warning.

The warning in this case is a spurious warning, which happens at the time
kconfig tries to detect symbols that have changed, to touch the empty
header files in include/config used for dependency-tracking by make.

Silence the warning when we read the old auto.conf file, since it is
perfectly legit that a symbol changed type since the previous call.

8357b48549 kconfig: fix randomising choice entries in presence of KCONFIG_ALLCONFIG
Currently, randconfig does randomise choice entries, unless KCONFIG_ALLCONFIG
is specified.

For example, given those two files (Thomas' test-case):

    ---8<--- Config.test.in
    config OPTIONA
        bool "Option A"

    choice
        prompt "This is a choice"

    config CHOICE_OPTIONA
        bool "Choice Option A"

    config CHOICE_OPTIONB
        bool "Choice Option B"

    endchoice

    config OPTIONB
        bool "Option B"
    ---8<--- Config.test.in

    ---8<--- config.defaults
    CONFIG_OPTIONA=y
    ---8<--- config.defaults

And running:
    ./scripts/kconfig/conf --randconfig Config.test.in

does properly randomise the two choice symbols (and the two booleans).

However, running:
    KCONFIG_ALLCONFIG=config.defaults \
    ./scripts/kconfig/conf --randconfig Config.test.in

does *not* reandomise the two choice entries, and only CHOICE_OPTIONA
will ever be selected. (OPTIONA will always be set (expected), and
OPTIONB will be be properly randomised (expected).)

This patch defers setting that a choice has a value until a symbol for
that choice is indeed set, so that choices are properly randomised when
KCONFIG_ALLCONFIG is set, but not if a symbol for that choice is set.

Changes v3 -> v4
  - fix previous issue where some choices would not be set, which would
    cause silentoldconfig to ask for them and was then breaking this
    workflow (as reported by Arnd and Sedat):
        KCONFIG_ALLCONFIG=foo.defconfig make randconfig
        make silentoldconfig </dev/nullo
    which I have tested (3h28min!) with:
        touch defconfig
        for(( i=0; i<10000; i++ )); do
            KCONFIG_ALLCONFIG=$(pwd)/defconfig make randconfig >/dev/null 2>&1
            make silentoldconfig </dev/null >/dev/null 2>&1 || break
        done
    which did not break at all.
  - change done in v3 (below) is already fixed by a previous patch

Changes v2 -> v3
  - ensure only one symbol is set in a choice

Changes v1 -> v2:
  - further postpone setting that a choice has a value until
    one is indeed set
  - do not print symbols that are part of an invisible choice

3b9a19e089 kconfig: loop as long as we changed some symbols in randconfig
Because of choice-in-a-choice constructs, it can happen that not all
symbols are assigned a value during randconfig, leading in rare cases
to this situation:

    ---8<--- choice-in-choice.in
    choice
        bool "A/B/C"
    config A
        bool "A"

    config B
        bool "B"
    if B
    choice
        bool "E/F"
    config E
        bool "E"
    config F
        bool "F"
    endchoice
    endif # B

    config C
        bool "C"
    endchoice
    ---8<---

    $ ./scripts/kconfig/conf --randconfig choice-in-choice.in
    [--SNIP--]
    $ ./scripts/kconfig/conf --silentoldconfig choice-in-choice.in </dev/null
    [--SNIP--]
    A/B/C
      1. A (A)
    > 2. B (B)
      3. C (C)
    choice[1-3]: 2
      E/F
      > 1. E (E) (NEW)
        2. F (F) (NEW)
      choice[1-2]: aborted!

    Console input/output is redirected. Run 'make oldconfig' to update
    configuration.

Fix this by looping in randconfig for as long as some symbol gets assigned
a value.

Note: this was spotted with the USB EHCI Debug Device Gadget (USB_G_DBGP),
which uses this choice-in-a-choice construct, and exhibits this problem.
The example above is just a stripped-down minimalist test-case.

193b40aeb5 kconfig: sort found symbols by relevance
When searching for symbols, return the symbols sorted by relevance.

Sorting is done as thus:
  - first, symbols that match exactly
  - then, alphabetical sort

Since the search can be a regexp, it is possible that more than one symbol
matches exactly. In this case, we can't decide which to sort first, so we
fallback to alphabeticall sort.

Explain this (new!) sorting heuristic in the documentation.

e6abf12a77 kconfig/conf: fix randconfig setting multiple symbols in a choice
Currently, randconfig may set more than one symbol in a given choice.
Given this config file:
    config A
        bool "A"
    if A
    choice
        bool "B/C/D"
    config B
        bool "B"
    config C
        bool "C"
    config D
        bool "D"
    endchoice
    endif # A

Then randconfig generates such .config files (case where A is not set is not
shown below for brevity), and where only the right-most .config is valid:
  CONFIG_A=y                  CONFIG_A=y                  CONFIG_A=y
  CONFIG_B=y                  CONFIG_B=y                  CONFIG_B=y
  CONFIG_C=y                  # CONFIG_C is not set       # CONFIG_C is not set
  # CONFIG_D is not set       CONFIG_D=y                  # CONFIG_D is not set

That is, in a randomised choice, the first symbol is always selected,
and at most one other symbol may be selected.

This is due to symbol randomised in a choice not being properly flagged
as having a value.

Fix that by flagging those symbols adequately: have a user-defined value,
and be not valid (to force recalculation of the symbol).

Note: if the choice is not conditional, then the randomisation is properly
done.

1278ebdbc3 mconf/nconf: mark empty menus/menuconfigs different from non-empty ones
Submenus are sometimes empty and it would be nice if there is
something that notifies us that we should not expect any content
_before_ we enter a submenu.

A new function menu_is_empty() was introduced and empty menus and

are marked by "--->".

Do not rely on the current implementation of ncurses that updates

Yann had some more ideas on improvements:

"What would be nice is an improvement that scales the choice window to
the number of entries in the choice. If there are a lot of choice
entries, then the choice popup grows in height (but does not overflow
the screen of course). So, instead of seeing only 6 entries, we'd see
as much as possible in the current screen.

Ditto for the width: the popup adapts to the longest prompt (but does
not overflow the screen either, of course), so prompts are not
truncated."

NOTE: This patch requires [1].

e983b7b17a kconfig/menu.c: fix multiple references to expressions in menu_add_prop()
menu_add_prop() applies upper menus' visibilities to actual prompts
by AND-ing the prompts visibilities with the upper menus ones.

This creates a further reference to the menu's visibilities and when
the expression reduction functions do their work, they may remove or
modify expressions that have multiple references, thus causing
unpredictable side-effects.

The following example Kconfig constructs a case where this causes
problems: a menu and a prompt which's visibilities depend on the same
symbol.  When invoking mconf with this Kconfig and pressing "Z" we
see a problem caused by a free'd expression still referenced by the
menu's visibility:

------------------------------------------------------------------------
mainmenu "Kconfig Testing Configuration"

config VISIBLE
	def_bool n

config Placeholder
	bool "Place holder"

menu "Invisible"
	visible if VISIBLE

config TEST_VAR
	bool "Test option" if VISIBLE

endmenu
------------------------------------------------------------------------

This patch fixes this problem by creating copies of the menu's
visibility expressions before AND-ing them with the prompt's one.

because get_symbol_prop() returns NULL.

this symbol when it parses sound/soc/fsl/Kconfig:

ced9cb1af1 localmodconfig: Process source kconfig files as they are found
A bug was reported that caused localmodconfig to not keep all the
dependencies of ATH9K. This was caused by the kconfig file:

In drivers/net/wireless/ath/Kconfig:

---
if ATH_CARDS

config ATH_DEBUG
        bool "Atheros wireless debugging"
        ---help---
          Say Y, if you want to debug atheros wireless drivers.
          Right now only ath9k makes use of this.

source "drivers/net/wireless/ath/ath5k/Kconfig"
source "drivers/net/wireless/ath/ath9k/Kconfig"
source "drivers/net/wireless/ath/carl9170/Kconfig"
source "drivers/net/wireless/ath/ath6kl/Kconfig"
source "drivers/net/wireless/ath/ar5523/Kconfig"
source "drivers/net/wireless/ath/wil6210/Kconfig"

endif
---

The current way kconfig works, it processes new source files after the
first file is completed. It creates an array of new source config files
and when the one file is finished, it continues with the next file.

Unfortunately, this means that it loses the fact that the source file is
within an "if" statement, and this means that each of these source file's
configs will not have the proper dependencies set.

As ATH9K requires ATH_CARDS set, the localmodconfig did not see that
dependency, and did not enable ATH_CARDS. When the oldconfig was run, it
forced ATH9K to be disabled.

0d8024c6eb kconfig: allow specifying the seed for randconfig
For reproducibility, it can be useful to be able to specify the
seed to use to seed the RNG.

Add a new KCONFIG_SEED environment variable which can be set to
the seed to use:
    $ make KCONFIG_SEED=42 randconfig
    $ sha1sum .config
    70a128c8dcc61303069e1be352cce64114dfcbca  .config
    $ make KCONFIG_SEED=42 randconfig
    $ sha1sum .config
    70a128c8dcc61303069e1be352cce64114dfcbca  .config

It's very usefull for eg. debugging the kconfig parser.

422c809f03 kconfig: fix randomising choice entries in presence of KCONFIG_ALLCONFIG
Currently, randconfig does randomise choice entries, unless KCONFIG_ALLCONFIG
is specified.

For example, given those two files (Thomas' test-case):

    ---8<--- Config.test.in
    config OPTIONA
        bool "Option A"

    choice
        prompt "This is a choice"

    config CHOICE_OPTIONA
        bool "Choice Option A"

    config CHOICE_OPTIONB
        bool "Choice Option B"

    endchoice

    config OPTIONB
        bool "Option B"
    ---8<--- Config.test.in

    ---8<--- config.defaults
    CONFIG_OPTIONA=y
    ---8<--- config.defaults

And running:
    ./scripts/kconfig/conf --randconfig Config.test.in

does properly randomise the two choice symbols (and the two booleans).

However, running:
    KCONFIG_ALLCONFIG=config.defaults \
    ./scripts/kconfig/conf --randconfig Config.test.in

does *not* reandomise the two choice entries, and only CHOICE_OPTIONA
will ever be selected. (OPTIONA will always be set (expected), and
OPTIONB will be be properly randomised (expected).)

This patch defers setting that a choice has a value until a symbol for
that choice is indeed set, so that choices are properly randomised when
KCONFIG_ALLCONFIG is set, but not if a symbol for that choice is set.

Also, as a side-efect, this patch fixes the following case:

    ---8<---
    choice
    config OPTION_A
        bool "Option A"
    config OPTION_B
        bool "Option B"
    config OPTION_C
        bool "Option C"
    endchoice
    ---8<---

which could previously generate such .config files:

    ---8<---                            ---8<---
    CONFIG_OPTION_A=y                   CONFIG_OPTION_A=y
    CONFIG_OPTION_B=y                   # CONFIG_OPTION_B is not set
    # CONFIG_OPTION_C is not set        CONFIG_OPTION_C=y
    ---8<---                            ---8<---

Ie., the first entry in a choice is always set, plus zero or one of
the other options may be set.

This patch ensures that only one option may be set for a choice.

61fa0e17f9 kconfig: fix randconfig tristate detection
Because the modules' symbole (CONFIG_MODULES) may not yet be set when
we check a symbol's tristate capabilty, we'll always find that tristate
symbols are booleans, even if we randomly decided that to enable modules:
sym_get_type(sym) always return boolean for tristates when modules_sym
has not been previously set to 'y' *and* its value calculated *and* its
visibility calculated, both of which only occur after we randomly assign
values to symbols.

Fix that by looking at the raw type of symbols. Tristate set to 'm' will
be promoted to 'y' when their values will be later calculated.

cdf0c2cfd7 kconfig/lxdialog: rationalise the include paths where to find {.n}curses{,w}.h
The current code does this:

    if [ -f /usr/include/ncursesw/curses.h ]; then
        echo '-I/usr/include/ncursesw -DCURSES_LOC="<ncursesw/curses.h>"'
    elif [ -f /usr/include/ncurses/ncurses.h ]; then
        echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses.h>"'
    elif [ -f /usr/include/ncurses/curses.h ]; then
        echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses/curses.h>"'
    [...]

This is merely inconsistent:
  - adding the full path to the directory in the -I directive,
  - especially since that path is already a sub-path of the system
    include path,
  - and then repeating the sub-path in the #include directive.

Rationalise each include directive:
  - only use the filename in the #include directive,
  - keep the -I directives: they are always searched for before the
    system include path; this ensures the correct header is used.

Using the -I directives and the filename-only in #include is more in
line with how pkg-config behaves, eg.:
    $ pkg-config --cflags ncursesw
    -I/usr/include/ncursesw

This paves the way for using pkg-config for CFLAGS, too, now we use it
to find the libraries.

a45c7dfb94 merge_config.sh: Avoid creating unnessary source softlinks
Viresh noticed when using merge_config.sh that a source softlink
was being created even when he didn't specify the -O option.

The problem arises due to the previous commit 409f117e2d
which added the -O option. Basically if -O is not specified,
we still pass '-O=.' to the make command, which then generates
a source softlink to ./

This patch adds an extra check so if there is no -O specified
to merge_config.sh, we don't pass one on to make.

     •  on plain menu entry
     •  in radiolist window
     •  in input windows for text, decimal or hexadecimal values
     •  in filename selection windows <F6> <F7>
     •  SymSearch specific help called by <F8> followed by <F1>
(3)  More reasonable window titles:
     Rename window title            s/README/Global help/
     Rename variable    s/nconf_readme/nconf_global_help/
     Rename window title       s/Instructions/Short help/

7d5bb96629 menuconfig: fix extended colors ncurses support
The ncurses library allows for extended colors. The support for extended
colors support depends on wide-character support. ncurses headers
enable extended colors (NCURSES_EXT_COLORS) only when wide-character
support is enabled (NCURSES_WIDECHAR).

The "make menuconfig" uses wide-character ncursesw library, which can be
compiled with wide-character support, but does not define NCURSES_WIDECHAR
and it's using headers without wide-character (and extended colors) support.

This fixes problems with colors on systems with enabled extended colors
(like PLD Linux). Without this patch "make menuconfig" is hard to use.

 "Here are two fixes I intended to send after v3.6-rc7, but failed to do
  so.  So please pull them for v3.7-rc1 and they will be picked up by
  stable.

  The first one fixes gcc -x <language> syntax in various build-time
  tests, which icecream and possible other gcc wrappers did not
  understand (and yes, icecream is going to be fixed as well).

  The second one fixes make tar-pkg so that unpacking the tarball does
  not replace the /lib -> /usr/lib symlink on recent Fedora releases."

b1e0d8b70f kbuild: Fix gcc -x syntax
The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.

This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.

Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

4eae518d4b localmodconfig: Fix localyesconfig to set to 'y' not 'm'
The kbuild target 'localyesconfig' has been same as 'localmodconfig'
since the commit 50bce3e "kconfig/streamline_config.pl: merge
local{mod,yes}config". The commit expects this script generates
different configure depending on target, but it was not yet implemented.

So I added code that sets to 'yes' when target is 'localyesconfig'.

67d34a6a39 kconfig: Document oldnoconfig to what it really does
The make target 'oldnoconfig' is a misnomer. It doesn't set new symbols
to 'n', but instead sets it to their default values.

Unfortunately, assuming that it actually did this, broke ktest in some
of its tests. For example, the tests to create a minimum config and even
a config bisect, depends on removing various configs and using
oldnoconfig to get rid of other configs that may have depended on it.

But because some configs that it was trying to disable, were in fact
default enabled, this caused those configs to re-enable and corrupt the
test.

I thought about fixing oldnoconfig, but I'm afraid that people are
already dependent on its current behavior. Instead, I'm just updating
the documentation to state that it sets the new symbols to their default
values and not to 'n'.

Ideally, this would be called, 'olddefconfig' and we have an
'oldnoconfig' that actually disables the new symbols. But it's useless
for me now. If it changed, ktest would need to be consistent between
each version, and that would be to difficult to detect. I'll handle this
issue with ktest with other means.

d4bb58b5cb localmodconfig: Check if configs are already set for selects
There are some cases that a required module does not have a prompt
and needs to have another module enabled that selects it to be set.
As localmodconfig is conservative and tries to make the minimum config
without breaking the user's kernel, or keeping the user from using
devices that were loaded when the lsmod was done, all modules that
select this module will also be enabled.

If you needed module A, but module A did not have a prompt but needed
module B to be selected, localmodconfig would make sure B was still
enabled. If not only B selected A, but C, D, E, F, and G also
selected A, then all of those would also be included, as well as the
modules they depend on. This ballooned the number of configs that
localmodconfig would keep.

The fix here is to process the depends first, and then record those
configs that did not have a prompt and needed to be selected.
After the depends are done, check what configs are needed to select
the configs in the list, and if a config that selects it is already
set, then we don't need to do anything else.

If no config that selects the config is set, then just pick one and
try again.

This change brought down the number of selected modules from 290
to 67! Both before and after were run against a config that had 3095
modules enabled.

Read in the entire config file. If there's a config that we depend on
that happens to be in the core set (not a module) then we do not need
to process it as a module.

Currently, we follow the entire depend and selects even if they
are enabled as core and not modules. By checking to make sure that we
only look at modules we can drop the count a little.

From one of my tests, localmodconfig went from taking 3095 set modules
down to 356 before this patch, and down to 290 modules after the change.

bb8187d35f MCA: delete all remaining traces of microchannel bus support.
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).

Prevent subtle surprises to both people working on the kconfig code
and people using make allnoconfig allyesconfig allmoconfig and
randconfig by only attempting to read a config file if
KCONFIG_ALLCONFIG is set.

Common sense suggests attempting to read the extra config files does
not make sense unless requested.  The documentation says the code
won't attempt to read the extra config files unless requested.
Current usage does not appear to include people depending on the code
reading the config files without the variable being set So do the
simple thing and stop reading config files when passed
all{no,yes,mod,def,rand}config unless KCONFIG_ALLCONFIG environment
variable is set.

5d09598d48 kconfig: fix new choices being skipped upon config update
Running `oldconfig' after any of the following configuration change:

either trivial addition, such as:

config A
	bool "A"

choice
	prompt "Choice ?"
	depends on A

	config CHOICE_B
		bool "Choice B"

	config CHOICE_C
		bool "Choice C"
endchoice

or more tricky change:

OLD KCONFIG                      |  NEW KCONFIG
                                 |

                                 |          bool "A"

                                 |
        config CHOICE_D          |          config CHOICE_D
                bool "Choice D"  |                  bool "Choice D"
endchoice                        |
                                 |          config CHOICE_E
                                 |                  bool "Choice E"
                                 |                  depends on A
                                 |  endchoice

will not cause the choice to be considered as NEW, and thus not be
asked. The cause of this behavior is that choice's novelty are computed
statically right after the saved configuration has been read. At this
point, the new dependency's value is still unknown and asserted to be
`no'. Moreover, no update to this decision is made afterward.

Correct this by dynamically evaluating a choice's novelty, and removing the
static evaluation.

37ae2d5998 kbuild: Fix compiler warning with assertion when calling 'fwrite'
Reinhard Tartler discovered a corner case of calling xfwrite() where the
length of the string is zero.

Arnaud Lacombe suggested to use assertion for the corner case, as
fwrite(3) is currently used:

 1) in comment printers. Empty comment are not allowed.
 2) in a callback passed to expr_print(), where the string printed is
    either NULL OR non-empty.
 3) in the lexer, auto-generated, and unused.

I feel using assertion is a good solution:

 1) It cleanly takes care of the above-mentioned corner case.
 2) It can be easily disabled by defining NDEBUG.
 3) It asserts xfwrite() is simply a wrapper for fwrite().

320d41bb15 merge_config.sh: fix bug in final check
Arnaud Lacombe pointed out the final checking that the requested configs
were included in the final .config was broken.

The example was that if you had a fragment that disabled
CONFIG_DECOMPRESS_GZIP applied to a normal defconfig, there would be no
final warning that CONFIG_DECOMPRESS_GZIP was acutally set in the final
.config.

This bug was introduced by me in v3 of the original patch, and the
following patch reverts the invalid change.

4b5f72145e kconfig: add merge_config.sh script
After noticing almost every distro has their own method of managing config
fragments, I went looking at some best practices, and wanted to try to
consolidate some of the different approaches so this fairly simple
infrastructure can be shared (and new distros/build systems don't have to
implement yet another config fragment merge script).

This script is most influenced by the Windriver tools used in the Yocto
Project, reusing some portions found there.

This script merges multiple config fragments, warning on any overridden
values.  It then sets any unspecified values to their default, then
finally checks to make sure no specified value was dropped due to
unsatisfied dependencies.

I'm sure this implementation won't work for everyone, and I expect it will
need to evolve to adapt for various use cases.  But I think its a
reasonable starting point.

364212fdda kconfig/streamline-config.pl: Fix parsing Makefile with variables
Thomas Lange reported that when he did a 'make localmodconfig', his
config was missing the brcmsmac driver, even though he had the module
loaded.

Looking into this, I found the file:
drivers/net/wireless/brcm80211/brcmsmac/Makefile
had the following in the Makefile:

MODULEPFX := brcmsmac

obj-$(CONFIG_BRCMSMAC)  += $(MODULEPFX).o

The way streamline-config.pl works, is parsing all the
 obj-$(CONFIG_FOO) += foo.o
lines to find that CONFIG_FOO belongs to the module foo.ko.

But in this case, the brcmsmac.o was not used, but a variable in its place.

By changing streamline-config.pl to remember defined variables in Makefiles
and substituting them when they are used in the obj-X lines, allows
Thomas (and others) to have their brcmsmac module stay configured
when it is loaded and running "make localmodconfig".

fa0ad6575f kconfig: adapt update-po-config to new UML layout
Commit 5c48b108 ("um: take arch/um/sys-x86 to arch/x86/um") broke the
make target update-po-config, as its symlink trick (again) fails.
(Previous breakage was fixed with commit bdc69ca4 ("kconfig: change
update-po-config to reflect new layout of arch/um").)

The new UML layout allows to drop the symlick trick entirely. And if,
one day, another architecture supports UML too, that should now work
without again breaking this make target.

3f198dfee4 kbuild: Fix help text not displayed in choice option.
Help text under choice menu is never displayed because it does not have
symbol name associated with it, however many kconfigs have help text
under choice, assuming that it will be displayed when user selects help.
for example in Kconfig if we have:
choice
        prompt "Choice"
        ---help---
           HELP TEXT ...

config A
        bool "A"

config B
        bool "B"

endchoice

Without this patch "HELP TEXT" is not displayed when user selects help
option when "Choice" is highlighted from menuconfig or xconfig or
gconfig.

This patch changes the logic in menu_get_ext_help to display help for
cases which dont have symbol names like choice.

2a11c8ea20 kconfig: Introduce IS_ENABLED(), IS_BUILTIN() and IS_MODULE()
Replace the config_is_*() macros with a variant that allows for grepping
for usage of CONFIG_* options in the code. Usage:

  if (IS_ENABLED(CONFIG_NUMA))

or

  #if IS_ENABLED(CONFIG_NUMA)

The IS_ENABLED() macro evaluates to 1 if the argument is set (to either 'y'
or 'm'), IS_BUILTIN() tests if the option is 'y' and IS_MODULE() test if
the option is 'm'. Only boolean and tristate options are supported.

eb4cf5a642 kconfig: fix missing "0x" prefix from S_HEX symbol in autoconf.h
The specialized printer for headers (espectially autoconf.h) is missing
fixup code for S_HEX symbol's "0x" prefix. As long as kconfig does not
warn for such missing prefix, this code is needed. Fix this.

In the same time, fix some nits in `header_print_symbol()'.

f98ee76955 kconfig/nconf: prevent segfault on empty menu
nconf does not check the validity of the current menu when help is
requested (with either <F2>, '?' or 'h'). This leads to a NULL pointer
dereference when an empty menu is encountered.

The following reduced testcase exposes the problem:

config DEP
        bool

menu "FOO"

config BAR
        bool "BAR"
        depends on DEP

endmenu

Issue will happen when entering menu "FOO" and requesting help.

nconf is the only front-end which do not filter the validity of the
current menu. Such filter can not really happen beforehand as other key
which does not deals with the current menu might be entered by the user,
so just bails out earlier if we encounter an invalid menu.

5416857867 kconfig/nconf: use the generic menu_get_ext_help()
nconf is the only front-end which does not use this helper, but prefer
to copy/paste the code. The test wrt. menu validity added in this
version of the code is bogus anyway as an invalid menu will get
dereferenced a few line below by calling menu_get_prompt().

For now, convert nconf to use menu_get_ext_help(), as do every other
front-end. We will deals with menu validity checks properly in a
separate commit.

This variable is not used outside of main() so there is not much reason keeping
it global. Ensure it is initialized as gcc has no way to know that normal
execution path expect only one option switch to be given on the command line
(except when we request help). As a result, we always initialize
`defconfig_file' before using it.

ec6452a5ec kconfig: do not overwrite symbol direct dependency in assignment
Considering the following configuration:

config F
    bool "F"

choice AB
    bool "AB"
config A
    bool "A"
config B
    bool "B"
endchoice

if A
config D
    bool
    default y if F
    select E
config E
    bool "E"
endif

if B
config D
    bool
    default y if F
    select E
config E
    bool "E"
endif

The following configuration:

 CONFIG_F=y
 CONFIG_A=y
 # CONFIG_B is not set
 CONFIG_D=y
 CONFIG_E=y

emits a spurious warning:

(D) selects E which has unmet direct dependencies (B)

If a symbol appears in two different branch of the tree, it should inherit the
dependency of both parent, not just the last one.

466de91835 kconfig: Avoid buffer underrun in choice input
commit 40aee729b3 ('kconfig: fix default
value for choice input') fixed some cases where kconfig would select
the wrong option from a choice with a single valid option and thus
enter an infinite loop.

However, this broke the test for user input of the form 'N?', because
when kconfig selects the single valid option the input is zero-length
and the test will read the byte before the input buffer.  If this
happens to contain '?' (as it will in a mips build on Debian unstable
today) then kconfig again enters an infinite loop.

7ad1227818 kconfig: fix undesirable side effect of adding "visible" menu attribute
This lead to non-selected, non-user-selectable options to be written
out to .config. This is not only pointless, but also preventing the
user to be prompted should any of those options eventually become
visible (e.g. by de-selecting the *_AUTO options the "visible"
attribute was added for.

Furthermore it is quite logical for the "visible" attribute of a menu
to control the visibility of all contained prompts, which is what the
patch does.

1137c56b74 kconfig: simplify select-with-unmet-direct-dependency warning
This is an attempt to simplify the expressing printed by kconfig when a
symbol is selected but still has direct unmet dependency.

First, the symbol reverse dependency is split in sub-expression. Then,
each sub-expression is checked to ensure that it does not contains the
unmet dependency. This removes the false-positive symbols and fixed symbol
which already have the correct dependency. Finally, only the symbol
responsible of the "select" is printed, instead of its full dependency tree.

8ef17fa2ef kconfig: Have streamline_config process menuconfigs too
Some menuconfigs in the Kconfig files have prompts and dependencies.
Currently, streamline_config misses these, and this can cause
streamline_config to keep modules enabled that should not be, and
even worse, not enable those that should.

This patch makes streamline_config process menuconfigs just like it

20d1904733 kconfig: Fix streamline_config to read multi line deps in Kconfig files
I noticed that some Kconfig files have multi line dependencies
that continue with a backslash. Those dependencies on the next
line will be missed by streamline_config.

For example:

config CS89x0
	tristate "CS89x0 support"
	depends on NET_ETHERNET && (ISA || EISA || MACH_IXDP2351 \
		|| ARCH_IXDP2X01 || MACH_MX31ADS)

The "|| ARCH_IXDP2X01 || MACH_MX31ADS)" will not be processed.

This patch adds code to handle this case.

In 60f33b8 (kconfig: get rid of stray a.o, support ncursesw, 2006-01-15),
support to link menuconfig with ncursesw library was added.  To compute
the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow
ncursesw to be used as a replacement ncurses.  However, when checking what
header file to include, we do not check /usr/include/ncursesw directory.

Add /usr/include/ncursesw to the list of directories that are checked.
With this patch, on my Debian Lenny box with libncursesw5-dev package but
not libncurses5-dev package, I can say "make menuconfig".
