2008-02-07kernel-doc: warn on badly formatted short descriptionRandy Dunlap1-0/+8
Make kernel-doc warn when a function/struct/union/typedef does not contain a properly formatted short description, such as: * scsi_devinfo: set up the dynamic device list or * scsi_devinfo - This warning is only generated when verbose (-v) mode is used. Also explain the -v command line option in the -h output.

2008-02-06kallsyms should prefer non weak symbolsPaulo Marques1-3/+34
When resolving symbol names from addresses with aliased symbol names, kallsyms_lookup always returns the first symbol, even if it is a weak symbol. This patch changes this by sorting the symbols with the weak symbols last before feeding them to the kernel. This way the kernel runtime isn't changed at all, only the kallsyms build system is changed. Another side effect is that the symbols get sorted by address, too. So, even if future binutils version have some bug in "nm" that makes it fail to correctly sort symbols by address, the kernel won't be affected by this. Mathieu says: I created a module in LTTng that uses kallsyms to get the symbol corresponding to a specific system call address. Unfortunately, all the unimplemented syscalls were all referring to the (same) weak symbol identifying an unrelated system call rather that sys_ni (or whatever non-weak symbol would be expected). Kallsyms was dumbly returning the first symbol that matched. This patch makes sure kallsyms returns the non-weak symbol when there is one, which seems to be the expected result.

2008-02-06remove support for un-needed _extratext sectionRobin Getz1-14/+10
When passing a zero address to kallsyms_lookup(), the kernel thought it was a valid kernel address, even if it is not. This is because is_ksym_addr() called is_kernel_extratext() and checked against labels that don't exist on many archs (which default as zero). Since PPC was the only kernel which defines _extra_text, (in 2005), and no longer needs it, this patch removes _extra_text support.

2008-02-03kconfig: ignore select of unknown symbolSam Ravnborg1-6/+3
We have had warnings for a long time about select of unknow symbol but the warnings does not really makes sense since we may select a symbol that is relevant and defined in one arch but not in another arch. And as long as we do not use a common set of Kconfig files for all archs lets just ignore this case. Previously we have used this to find bad uses of select but we need a more relaible method to do so. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>

2008-02-01USB: handle idVendor of 0x0000Greg Kroah-Hartman1-1/+1
Some crazy devices in the wild have a vendor id of 0x0000. If we try to add a module alias with this id, we just can't do it due to a check in the file2alias.c file. Change the test to verify that both the vendor and product ids are 0x0000 to show a real "blank" module alias. Note, the module-init-tools package also needs to be changed to properly generate the depmod tables.

2008-01-28kbuild: warn about ld added unique sectionsSam Ravnborg1-2/+40
If there is a mixture of specifying sections for code in gcc and assembler then if the assembler code do not add the "ax" flags the linker will see this as two different sections and generate unique sections for each. ld does so by adding a dot and a number. Teach modpost to warn if a section shows up that match this pattern - but do this only for non-debug sections. It will result in warnings like this: WARNING: vmlinux.o (.sched.text.1): unexpected section name. The (.[number]+) following section name are ld generated and not expected. Did you forget to use "ax"/"aw" in a .S file? Note that for example <linux/init.h> contains section definitions for use in .S files. All warnings seen with a defconfig build for: x86 (32+64bit) and sparc64 has been fixed (via respective maintainers). arm, powerpc (64 bit), s390 (32 bit), ia64, alpha, sh4 checked - no warnings seen with a defconfig build.

2008-01-28kbuild: add verbose option to Section mismatch reporting in modpostSam Ravnborg2-29/+227
If the config option CONFIG_SECTION_MISMATCH is not set and we see a Section mismatch present the following to the user: modpost: Found 1 section mismatch(es). To see additional details select "Enable full Section mismatch analysis" in the Kernel Hacking menu (CONFIG_SECTION_MISMATCH). If the option CONFIG_SECTION_MISMATCH is selected then be verbose in the Section mismatch reporting from mdopost. Sample outputs: WARNING: o-x86_64/vmlinux.o(.text+0x7396): Section mismatch in reference from the function discover_ebda() to the variable .init.data:ebda_addr The function discover_ebda() references the variable __initdata ebda_addr. This is often because discover_ebda lacks a __initdata annotation or the annotation of ebda_addr is wrong. WARNING: o-x86_64/vmlinux.o(.data+0x74d58): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:pci_plx9050_exit() The variable pci_serial_quirks references the function __devexit pci_plx9050_exit() If the reference is valid then annotate the variable with __exit* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: o-x86_64/vmlinux.o(__ksymtab+0x630): Section mismatch in reference from the variable __ksymtab_arch_register_cpu to the function .cpuinit.text:arch_register_cpu() The symbol arch_register_cpu is exported and annotated __cpuinit Fix this by removing the __cpuinit annotation of arch_register_cpu or drop the export.

2008-01-28Use separate sections for __dev/__cpu/__mem code/dataSam Ravnborg1-15/+39
Introducing separate sections for __dev* (HOTPLUG), __cpu* (HOTPLUG_CPU) and __mem* (MEMORY_HOTPLUG) allows us to do a much more reliable Section mismatch check in modpost. We are no longer dependent on the actual configuration of for example HOTPLUG. This has the effect that all users see much more Section mismatch warnings than before because they were almost all hidden when HOTPLUG was enabled. The advantage of this is that when building a piece of code then it is much more likely that the Section mismatch errors are spotted and the warnings will be felt less random of nature.

2008-01-28kbuild: introduce blacklisting in modpostSam Ravnborg1-177/+128
Change the logic in modpost so we identify all the bad combinations of sections that refer to other sections. Compared to the previous approach we are much less dependent on knowledge of what additional sections the tool chain uses and thus we can keep the false positives low. The implmentation is changed to use a table based lookup and we now check all combinations in first pass so we no longer need separate passes for init and exit sections. Tested that the same warnings are generated for an allyesconfig build without CONFIG_HOTPLUG.

2008-01-28kbuild: try harder to find symbol names in modpostSam Ravnborg2-2/+19

Kconfig is powerfull tool. So powerfull that more and more software projects are using it for configuration. So instead of fixing some of them one by one, lets fix it in kernel and wait for sync.
