2011-07-02kconfig/conf: reduce the scope of `defconfig_file'Arnaud Lacombe1-3/+1
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. Signed-off-by: Arnaud Lacombe <lacombar@gmail.com>

2011-07-01kconfig: introduce specialized printerArnaud Lacombe4-128/+266
Make conf_write_symbol() grammar agnostic to be able to use it from different code path. These path pass a printer callback which will print a symbol's name and its value in different format. conf_write_symbol()'s job become mostly only to prepare a string for the printer. This avoid to have to pass specialized flag to generic functions Signed-off-by: Arnaud Lacombe <lacombar@gmail.com> [mmarek: rebased on top of de12518 (kconfig: autogenerated config_is_xxx macro)] Signed-off-by: Michal Marek <mmarek@suse.cz>
2011-06-24kconfig: do not overwrite symbol direct dependency in assignmentArnaud Lacombe1-1/+1
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.

2011-06-24headers_install: fix __packed in exported kernel headersMarkus Trippelsdorf1-0/+1
checkpatch.pl warns about using __attribute__((packed)) in kernel headers: "__packed is preferred over __attribute__((packed))". If one follows that advice it could cause problems in the exported header files, because the outside world doesn't know about this shortcut. For example busybox will fail to compile: CC miscutils/ubi_attach_detach.o In file included from miscutils/ubi_attach_detach.c:27:0: /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’ /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here ... Fix the problem by substituting __packed with __attribute__((packed)) in the header_install.pl script.

2011-06-16docproc: cleanup brace placementJesper Juhl1-12/+5
The placement of the opening brace "{" after 'if' statements in scripts/docproc.c is inconsistent. Most are placed on the same line as the 'if' statement itself as per CodingStyle, but a few are not. This patch cleans up the inconsistency. We save a few source lines and the file then uses the same style throughout, which is nice.

2011-06-13bootgraph.pl: relax timing information requirementsAndrew Murray1-1/+1
This patch removes the assumption of the bootgraph.pl script that the timing information reported by PRINTK_TIME will contain at least one entry with a time of less than 100 seconds. Not all boards correctly reset the system timer and in many cases the inital times reported by PRINTK_TIME is high. When this occurs the bootchart.pl script fails to give any useful output.

2011-05-26ftrace/recordmcount: Avoid STT_FUNC symbols as base on ARMRabin Vincent1-0/+8
While find_secsym_ndx often finds the unamed local STT_SECTION, if a section has only one function in it, the ARM toolchain generates the STT_FUNC symbol before the STT_SECTION, and recordmcount finds this instead. This is problematic on ARM because in ARM ELFs, "if a [STT_FUNC] symbol addresses a Thumb instruction, its value is the address of the instruction with bit zero set (in a relocatable object, the section offset with bit zero set)". This leads to incorrect mcount addresses being recorded. Fix this by not using STT_FUNC symbols as the base on ARM.
