2008-06-12kbuild: ignore powerpc specific symbols in modpostSam Ravnborg1-5/+20
Kumar Gala <galak@kernel.crashing.org> wrote: We have a case in powerpc in which we want to link some library routines with all module objects. The routines are intended for handling out-of-line function call register save/restore so having them as EXPORT_SYMBOL() is counter productive (we do also need to link the same "library" code into the kernel). Without this patch a powerpc build would error out and fail to build modules with the added register save/restore module. There were two obvious solutions: 1) To link the .o file before the modpost stage 2) To ignore the symbols in modpost Option 1) was ruled out because we do not have any separate linking stage for single file modules. This patch implements option 2 - and do so only for powerpc. The symbols we ignore are all undefined symbols named: _restgpr_*, _savegpr_*, _rest32gpr_*, _save32gpr_* Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Kumar Gala <galak@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org>
2008-06-06update checkpatch.pl to version 0.19Andy Whitcroft1-102/+182
This version is a bit of a whopper. This version brings a few new checks, improvements to a number of checks mostly through modifications to the way types are parsed, several fixes to quote/comment handling, as well as the usual slew of fixes for false positives. Of note: - return is not a function and is now reported, - preprocessor directive detection is loosened to match C99 standard, - we now intuit new type modifiers, and - comment handling is much improved Andy Whitcroft (18): Version: 0.19 fix up a couple of missing newlines in reports colon to parenthesis spacing varies on asm values: #include is a preprocessor statement quotes: fix single character quotes at line end add typedef exception for the non-pointer "function types" kerneldoc parameters must be on one line, relax line length types: word boundary is not always required improved #define bracketing reports uninitialized_var is an annotation not a function name possible types: add possible modifier handling possible types: fastcall is a type modifier types: unsigned is not a modifier on all types static/external initialisation to zero should allow modifiers checkpatch: fix recognition of preprocessor directives -- part 2 comments: fix inter-hunk comment tracking return is not a function do not report include/asm/foo.h use in include/linux/foo.h return is not a function -- tighten test [jengelh@computergmbh.de: fix recognition of preprocessor directives] Signed-off-by: Andy Whitcroft <apw@shadowen.org> Cc: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-06-01kbuild: fix $(src) assignmnet with external modulesSam Ravnborg1-0/+6
When we introduced support for KBUILD_EXTRA_SYMBOLS we started to include the externam module's kbuild file when doing the final modpost step. As external modules often do: ccflags-y := -I$(src) We had problems because $(src) was unassinged and gcc then used the next parameter for -I resulting in strange build failures. Fix is to assign $(src) and $(obj) when building external modules.

2008-05-04modpost: i2c aliases need no trailing wildcardJean Delvare1-9/+26
Not all device types need a wildcard at the end of their module aliases. In particular, for i2c module aliases, the trailing wildcard is not only unneeded, it could also cause the wrong driver to be loaded. As I2C devices have no IDs, i2c module aliases are simple, arbitrary device names. For example: $ /sbin/modinfo lm90 filename: /lib/modules/2.6.25-git18/kernel/drivers/hwmon/lm90.ko author: Jean Delvare <khali@linux-fr.org> description: LM90/ADM1032 driver license: GPL vermagic: 2.6.25-git18 mod_unload depends: hwmon alias: i2c:lm90* alias: i2c:adm1032* alias: i2c:lm99* alias: i2c:lm86* alias: i2c:max6657* alias: i2c:adt7461* alias: i2c:max6680* $ This would cause trouble if one I2C chip name matches the beginning of another I2C chip name and both chips are supported by different drivers. For example, an i2c device named lm9042 would cause the lm90 driver to be loaded, while it doesn't support that device. This case has yet to be seen in practice, but still, I'd like to fix it now. The cleanest fix is to remove the trailing wildcard from i2c module aliases. Here's a patch doing this. Not all device type aliases need a trailing wildcard, in particular the i2c aliases don't. Don't add a wildcard by default in do_table(), instead let each device type handler add it if needed. I have tested types acpi, dmi, eisa, i2c, ide, ieee1394, input, pci, pcmcia, platform, pnp, scsi, serio, ssb and usb. Other types (ccw, of, vio, parisc, sdio and virtio) are untested.

2008-04-28kernel-doc: detect/prevent duplicate doc section namesRandy Dunlap1-7/+13
I saw this problem recently. With this kernel-doc: * Note: some important info * * Note: other important info kernel-doc uses the "section name" (preceding the ':', like "Note") as a hash key for storing the descriptive text ("blah important info"). It is (was) possible to have duplicate (colliding) section names, without any kind of warning or error. kernel-doc happily used the latter descriptive text for all instances of printing the <section-name> descriptive text and the former important info was lost. One way to "fix" this is to modify the kernel-doc comments, e.g.: * Note1: foo bar * * Note.2: blah zay For now, kernel-doc will signal an error when it sees colliding section names like this.

This patch adds a new command line option -E to modpost, expecting a symbol file as an argument which is read prior to symbol processing. -E can be supplied multiple times for as many files as is needed. When building kernel modules that depend on other modules not in the main kernel tree, modpost complains about undefined symbols: # make -C /path/to/linux/kernel M=/path/to/my/module ... Building modules, stage 2. .... WARNING: "rt_copy_buf" [/home/rich/osc_etl_rtw/osc_kmod.ko] undefined! ...etc This situation occurs when modpost processes the new module's symbols. When it finds symbols not exported by the mainline kernel, it issues this warning. The patch adds a new command line option -e to modpost which expects a symbol file as an argument. The symbols listed in this file are added to modpost's symbol tables during startup. -e can be supplied as often as required. This patch works together with the second patch.

2008-03-05update checkpatch.pl to version 0.15Andy Whitcroft1-117/+206
This version brings a number of minor fixes updating the type detector and the unary tracker. It also brings a few small fixes for false positives. It also reverts the --file warning. Of note: - limit CVS checks to added lines - improved type detections - fixes to the unary tracker Andy Whitcroft (13): Version: 0.15 EXPORT_SYMBOL checks need to accept array variables export checks must match DECLARE_foo and LIST_HEAD possible types: cleanup debugging missing line values: track values through preprocessor conditional paths typeof is actually a type possible types: detect definitions which cross lines values: include line numbers on value debug information values: ensure we find correctly record pending brackets values: simplify the brace history stack CVS keyword checks should only apply to added lines loosen spacing for comments allow braces for single statement blocks with multiline conditionals Harvey Harrison (1): checkpatch: remove fastcall Ingo Molnar (1): checkpatch.pl: revert wrong --file message Uwe Kleine-Koenig (1): fix typo "goot" -> "good" Signed-off-by: Andy Whitcroft <apw@shadowen.org> Cc: Randy Dunlap <rdunlap@xenotime.net> Cc: Joel Schopp <jschopp@austin.ibm.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-02-24kernel-doc: fix function-pointer-parameter parsingRichard Kennedy1-3/+3
When running "make htmldocs" I'm seeing some non-fatal perl errors caused by trying to parse the callback function definitions in blk-core.c. The errors are "Use of uninitialized value in concatenation (.)..." in combination with: Warning(linux-2.6.25-rc2/block/blk-core.c:1877): No description found for parameter '' The function pointers are defined without a * i.e. int (drv_callback)(struct request *) The compiler is happy with them, but kernel-doc isn't. This patch teaches create_parameterlist in kernel-doc to parse this type of function pointer definition, but is it the right way to fix the problem ? The problem only seems to occur in blk-core.c. However with the patch applied, kernel-doc finds the correct parameter description for the callback in blk_end_request_callback, which is doesn't normally. I thought it would be a bit odd to change to code to use the more normal form of function pointers just to get the documentation to work, so I fixed kernel-doc instead - even though this is teaching it to understand code that might go away (The comment for blk_end_request_callback says that it should not be used and will removed at some point).

XXXINIT_TO_INIT and XXXEXIT_TO_EXIT warnings use the reversed symbol name order in the suggestion, e.g.: WARNING: vmlinux.o(.meminit.text+0x36c): Section mismatch in reference from the function free_area_init_core() to the function .init.text:setup_usemap() The function __meminit free_area_init_core() references a function __init setup_usemap().

2008-02-14Linux Kernel Markers: create modpost fileMathieu Desnoyers3-1/+177
This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous to the Module.symvers file, the build will now write a Module.markers file when CONFIG_MARKERS=y is set. This file lists the name, defining module, and format string of each marker, separated by \t characters. This simple text file can be used by offline build procedures for instrumentation code, analogous to how System.map and Module.symvers can be useful to have for kernels other than the one you are running right now. The strings are made easy to extract by having the __trace_mark macro define the name and format together in a single array called __mstrtab_* in the __markers_strings section. This is straightforward and reliable as long as the marker structs are always defined by this macro. It is an unreasonable amount of hairy work to extract the string pointers from the __markers section structs, which entails handling a relocation type for every machine under the sun.

2008-02-14kconfig: fix select in combination with defaultRoman Zippel1-13/+21
> The attached .config (with current -git) results in a compile > error since it contains: > > CONFIG_X86=y > # CONFIG_EMBEDDED is not set > CONFIG_SERIO=m > CONFIG_SERIO_I8042=y > > Looking at drivers/input/serio/Kconfig I simply don't get how this > can happen. You've hit the rather subtle rules of select vs default. What happened is that SERIO is selected to m, but SERIO_I8042 isn't selected so the default of y is used instead. We already had the problem in the past that select and default don't work well together, so this patch cleans this up and makes the rule hopefully more straightforward. Basically now the value is calculated like this: (value && dependency) || select where the value is the user choice (if available and the symbol is visible) or default. In this case it means SERIO and SERIO_I8042 are both set to y due to their default and if SERIO didn't had the default, then the SERIO_I8042 value would be limited to m due to the dependency. I tested this patch with more 10000 random configs and above case is the only the difference that showed up, so I hope there is nothing that depended on the old more complex and subtle rules.
