2010-10-04kconfig: Use PATH_MAX instead of 128 for path buffer sizes.Will Newton

2010-09-30kconfig: Don't go out from read config loop when you read new symbolNaohiro Aota
commit 8baefd30b5b0101aa07aa75da44a9eee881eed28 of linux-next replaced a `switch()' statement with some `if()' statements, but left `break's in the `switch()' statement untouched.

2010-09-20kconfig: fix menuconfig on debian lennyJunio C Hamano
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".

2010-09-13nconfig: Fix help for choice menusStephen Boyd
When getting the help for a choice menu with a help section (for example the "Choose SLAB allocator" menu) nconfig pops up a window with nothing inside it. This is due to show_help() passing an empty string to show_scroll_win()'s 3rd argument. The option really does have help though, but it isn't a config symbol, so just add the help text for the option, and don't try to add anything else like the config option name.

2010-08-12kconfig: fix tristate choice with minimal configSam Ravnborg
If a minimal config did not specify the value of all choice values, the resulting configuration could have wrong values. Consider following example: config M def_bool y option modules choice prompt "choice list" config A tristate "a" config B tristate "b" endchoice With a defconfig like this: CONFIG_M=y CONFIG_A=y The resulting configuration would have CONFIG_A=m which was unexpected. The problem was not not all choice values were set and thus kconfig calculated a wrong value. The fix is to set all choice values when we read a defconfig files. conf_set_all_new_symbols() is refactored such that random choice values are now handled by a dedicated function. And new choice values are set by set_all_choice_values(). This was not the minimal fix, but the fix that resulted in the most readable code.

2010-08-03kconfig: add savedefconfigSam Ravnborg
savedefconfig will save a minimal config to a file named "defconfig". The config symbols are saved in the same order as they appear in the menu structure so it should be possible to map them to the relevant menus if desired. The implementation was tested against several minimal configs for arm which was created using brute-force. There was one regression related to default numbers which had their valid range further limited by another symbol. Sample: config FOO int "foo" default 4 config BAR int "bar" range 0 FOO If FOO is set to 3 then BAR cannot take a value higher than 3. But the current implementation will set BAR equal to 4. This is seldomly used and the final configuration is OK, and the fix was non-trivial. So it was documented in the code and left as is.
