2013-02-25Merge branch 'kbuild/rc-fixes' into kbuild/kconfigMichal Marek
There is one kconfig fix in the rc-fixes branch that I forgot to submit for 3.8, so let's add it to the kconfig branch for 3.9-rc1.
2013-02-19kbuild: Fix missing '\n' for NEW symbols in yes "" | make oldconfig >conf.newBen Hutchings
According to Documentation/kbuild/kconfig.txt, the commands: yes "" | make oldconfig >conf.new grep "(NEW)" conf.new should list the new config symbols with their default values. However, currently there is no line break after each new symbol. When kconfig is interactive the user will type a new-line at this point, but when non-interactive kconfig must print it.

2012-11-20kconfig: get CONFIG_ prefix from the environmentYann E. MORIN
Currently, the CONFIG_ prefix is hard-coded in the kconfig frontends executables. This means that two projects that use kconfig with different prefixes can not share the same kconfig frontends.

2012-11-20kconfig: add a function to get the CONFIG_ prefixYann E. MORIN
Currently, we get the CONFIG_ prefix via the CONFIG_ macro, which means the CONFIG_ prefix is hard-coded at compile time. This goes against having a run-time defined CONFIG_ prefix. Add a function that returns the CONFIG_ prefix to use (but keep the current hard-coded behavior, to be changed in a later patch). To avoid touching all the code that uses the CONFIG_ macro, we just undef it, and define it to be a call to the function. Signed-off-by: "Yann E.

2012-11-20menuconfig: fix extended colors ncurses supportKrzysztof Mazur
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.

2012-10-03kbuild: Fix gcc -x syntaxJean Delvare
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.

2012-07-26kconfig: Document oldnoconfig to what it really doesSteven Rostedt
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.

2012-06-19localmodconfig: Check if configs are already set for selectsSteven Rostedt
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. Tested-by: John David Yost <johnyost@ptd.net> # AlleyTrotter Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
