modpost: Fix modpost license checking of vmlinux.o

2012-04-10T03:52:56Z

Commit f02e8a6596b7 ("module: Sort exported symbols") sorts symbols placing each of them in its own elf section. This sorting and merging into the canonical sections are done by the linker. Unfortunately modpost to generate Module.symvers file parses vmlinux.o (which is not linked yet) and all modules object files (which aren't linked yet). These aren't sanitized by the linker yet. That breaks modpost that can't detect license properly for modules. This patch makes modpost aware of the new exported symbols structure. [ This above is a slightly corrected version of the explanation of the problem, copied from commit 62a2635610db ("modpost: Fix modpost's license checking V3"). That commit fixed the problem for module object files, but not for vmlinux.o. This patch fixes modpost for vmlinux.o. ] Signed-off-by: Frank Rowand Signed-off-by: Alessio Igor Bogani Signed-off-by: Linus Torvalds

mod/file2alias: make modpost compile on darwin again

commit e49ce14150c64b29a8dd211df785576fa19a9858 breaks cross compiling the linux kernel on darwin hosts. This fix introduce some minimal glue to adopt linker section handling for darwin hosts.

ARM: 7324/1: modpost: Fix section warnings for ARM for many compilers

2012-02-15T11:04:36Z

It turns out that many compilers don't show section warnings on ARM currently because handling for ARM_CALL relocs are missing from modpost.c. Based on commit c2e26114 ([ARM] 3205/1: Handle new EABI relocations when loading kernel modules) it seems that R_ARM_PC24, R_ARM_CALL and R_ARM_JUMP24 can be handled the same way. Note that at least Debian libc6-dev is missing defines for both R_ARM_CALL and R_ARM_JUMP24 in /usr/include/elf.h. So for now we need to define them in modpost.c if not defined.

module: fix broken isapnp handling in file2alias

2012-02-14T00:32:15Z

Handling of isapnp module aliases was broken by commit 626596e295d477c0fefa08cd5daa7dd011b1bb2c by changing "isapnp" string to "isa". The code was then modified by commit e49ce14150c64b29a8dd211df785576fa19a9858 but this bug remained. Change the string back to "isapnp". Signed-off-by: Ondrej Zary Signed-off-by: Rusty Russell

x86/cpu: Clean up modalias feature matching

2012-02-13T23:24:26Z

We currently include commas on both sides of the feature ID in a modalias, but this prevents the lowest numbered feature of a CPU from being matched. Since all feature IDs have the same length, we do not need to worry about substring matches, so omit commas from the modalias entirely. Avoid generating multiple adjacent wildcards when there is no feature ID to match. Signed-off-by: Ben Hutchings Acked-by: Thomas Renninger Acked-by: H. Peter Anvin Signed-off-by: Greg Kroah-Hartman

Add driver auto probing for x86 features v4

2012-01-27T00:44:41Z

There's a growing number of drivers that support a specific x86 feature or CPU. Currently loading these drivers currently on a generic distribution requires various driver specific hacks and it often doesn't work. This patch adds auto probing for drivers based on the x86 cpuid information, in particular based on vendor/family/model number and also based on CPUID feature bits. For example a common issue is not loading the SSE 4.2 accelerated CRC module: this can significantly lower the performance of BTRFS which relies on fast CRC. Another issue is loading the right CPUFREQ driver for the current CPU. Currently distributions often try all all possible driver until one sticks, which is not really a good way to do this. It works with existing udev without any changes. The code exports the x86 information as a generic string in sysfs that can be matched by udev's pattern matching. This scheme does not support numeric ranges, so if you want to handle e.g. ranges of model numbers they have to be encoded in ASCII or simply all models or families listed. Fixing that would require changing udev. Another issue is that udev will happily load all drivers that match, there is currently no nice way to stop a specific driver from being loaded if it's not needed (e.g. if you don't need fast CRC) But there are not that many cpu specific drivers around and they're all not that bloated, so this isn't a particularly serious issue. Originally this patch added the modalias to the normal cpu sysdevs. However sysdevs don't have all the infrastructure needed for udev, so it couldn't really autoload drivers. This patch instead adds the CPU modaliases to the cpuid devices, which are real devices with full support for udev. This implies that the cpuid driver has to be loaded to use this. This patch just adds infrastructure, some driver conversions in followups.
