2006-02-22kbuild: do not warn when unwind sections references .init/.exit sectionsSam Ravnborg
Andrew Morton reported a number of false positives for ia64 - like these: WARNING: drivers/acpi/button.o - Section mismatch: reference to .init.text: from .IA_64.unwind.init.text after '' (at offset 0x0) WARNING: drivers/acpi/button.o - Section mismatch: reference to .exit.text: from .IA_64.unwind.exit.text after '' (at offset 0x0) WARNING: drivers/acpi/processor.o - Section mismatch: reference to .init.text: from .IA_64.unwind after '' (at offset 0x1e8) They are all false positives - or at least the .c code looks OK. It is not known why sometimes a section name is appended and sometimes not. Fix is to accept references from all sections that includes "unwind." in the name.

2006-02-22kbuild: fix modpost compile with older gccakpm@osdl.org
The kernel now requires that CC be 3.1.0 or higher. But we shouldn't place that requirement upon HOSTCC unless we really need to. Fixes my ia64 problem. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-02-19kbuild: fix segfault in modpostSam Ravnborg
Do not try to look up section name until we know it is not a special section. Otherwise we will address outside legal space and segfault. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-02-19kbuild: do not segfault in modpost if MODVERDIR is not definedSam Ravnborg
A combination of calling modpost with option -a and MODVERDIR undefined caused segmentation fault. So provide a default value and accept the error messages it generates instead. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-02-19kbuild: check for section mismatch during modpost stageSam Ravnborg
Section mismatch is identified as references to .init* sections from non .init sections. And likewise references to .exit.* sections outside .exit sections. .init.* sections are discarded after a module is initialized and references to .init.* sections are oops candidates. .exit.* sections are discarded when a module is built-in and thus references to .exit are also oops candidates. The checks were possible to do using 'make buildcheck' which called the two perl scripts: reference_discarded.pl and reference_init.pl. This patch just moves the same functionality inside modpost and the scripts are then obsoleted. They will though be kept for a while so users can do double checks - but note that some .o files are skipped by the perl scripts so result is not 1:1. All credit for the concept goes to Keith Owens who implemented the original perl scrips - this patch just moves it to modpost. Compared to the perl script the implmentation in modpost will be run for each kernel build - thus catching the error much sooner, but the downside is that the individual .o file are not always identified.

2006-02-19kbuild: warn about duplicate exported symbolsSam Ravnborg

2006-02-19kbuild: improved modversioning support for external modulesSam Ravnborg
With following patch a second option is enabled to obtain symbol information from a second external module when a external module is build. The recommended approach is to use a common kbuild file but that may be impractical in certain cases. With this patch one can copy over a Module.symvers from one external module to make symbols (and symbol versions) available for another external module.

2006-01-04[PATCH] Input: add modalias supportRusty Russell
Here's the patch for modalias support for input classes. It uses comma-separated numbers, and doesn't describe all the potential keys (no module currently cares, and that would make the strings huge). The changes to input.h are to move the definitions needed by file2alias outside __KERNEL__. I chose not to move those definitions to mod_devicetable.h, because there are so many that it might break compile of something else in the kernel. The rest is fairly straightforward.

2005-12-26kbuild: set correct KBUILD_MODNAME when using well known kernel symbols as ↵Ustyugov Roman
module names This patch fixes a problem when we use well known kernel symbols as module names. For example, if module source name is current.c, idle_stack.c or etc., we have a bad KBUILD_MODNAME value. For example, KBUILD_MODNAME will be "get_current()" instead of "current", or "(init_thread_union.stack)" instead of "idle_task". The trick is to define a stringify macro on the commandline - named KBUILD_STR for namespace reasons - and then to stringify the module name. There are a few uses of KBUILD_MODNAME throughout the tree but the usage is for debug and will not be harmed by this change so left untouched for now. While at it KBUILD_BASENAME was changed too. Any spinlock usage in the unix module would have created wrong section names without it. Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME. Original patch from Ustyogov Roman - all bugs introduced by me. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2005-12-25kbuild: Fix crc-error warning on modulesLuke Yang
This is the patch for the following issue: In include/linux/module.h, "__crc_" and "__ksymtab_" are hard coded to be the prefix for some kinds of symbols (CRC symbol and ksymtab section). But in script /mod/modpost.c, MODULE_SYMBOL_PREFIX##"__crc_" is used as the prefix to search CRC symbols. So if an architecture (such as h8300 or Blackfin) defines MODULE_SYMBOL_PREFIX as not NULL ("_"), modpost will always warn about "no invalid crc". And it is the same with KSYMTAB_PFX.

2005-07-13[PATCH] kbuild: modpost needs to cope with new glibc elf header on sparcFabio Massimo Di Nitto
Recently a change in the glibc elf.h header has been introduced causing modpost to spawn tons of warnings (like the one below) building the kernel on sparc: [SNIP] *** Warning: "current_thread_info_reg" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined! *** Warning: "" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined! *** Warning: "" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined! [SNIP] Ben Collins discovered that the STT_REGISTERED definition in glibc did change and that this change needs to be propagated to modpost. glibc change: -#define STT_REGISTER 13 /* Global register reserved to app. */ +#define STT_SPARC_REGISTER 13 /* Global register reserved to app. */ I did and tested this simple patch to maintain compatibility with newer (>= 2.3.4) and older (<= 2.3.2) glibc.

2005-07-06[PATCH] openfirmware: generate device table for userspaceJeff Mahoney
This converts the usage of struct of_match to struct of_device_id, similar to pci_device_id. This allows a device table to be generated, which can be parsed by depmod(8) to generate a map file for module loading. In order for hotplug to work with macio devices, patches to module-init-tools and hotplug must be applied.

2005-04-22[PATCH] USB: scripts/mod/file2alias.c: handle numeric ranges for USB bcdDeviceRoman Kagan
Another attempt at that... The attached patch fixes the longstanding problem with USB bcdDevice numeric ranges incorrectly converted into patterns for MODULE_ALIAS generation. Previously it put both the lower and the upper limits into the pattern, dlXdhY, making it impossible to fnmatch against except for a few special cases, like dl*dh* or dlXdhX. The patch makes it generate multiple MODULE_ALIAS lines covering the whole range with fnmatch-able patterns. E.g. for a range between 0x0001 and 0x8345 it gives the following patterns: 000[1-9] 00[1-9]* 0[1-9]* [1-7]* 8[0-2]* 83[0-3]* 834[0-5] Since bcdDevice is 2 bytes wide = 4 digits in hex representation, the max no. of patters is 2 * 4 - 1 = 7. The values are BCD (binary-coded decimals) and not hex, so patterns using a dash seem to be safe regardless of locale collation order. The patch changes bcdDevice part of the alias from dlXdhY to dZ, but this shouldn't have big compatibility issues because fnmatch()-based modprobing hasn't yet been widely used. Besides, the most common (and almost the only working) case of dl*dh* becomes d* and thus continues to work. The patch is against 2.6.12-rc2, applies to -mm3 with an offset. The matching patch to fix the MODALIAS environment variable now generated by the usb hotplug function follows.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
