module: use kflagstab instead of *_gpl sections

2026-03-31T23:42:52Z

Read kflagstab section for vmlinux and modules to determine whether kernel symbols are GPL only. This patch eliminates the need for fragmenting the ksymtab for infering the value of GPL-only symbol flag, henceforth stop populating *_gpl versions of the ksymtab and kcrctab in modpost.

module: populate kflagstab in modpost

2026-03-31T23:42:52Z

This patch adds the ability to create entries for kernel symbol flag bitsets in kflagstab. Modpost populates only the GPL-only flag for now. Signed-off-by: Siddharth Nayyar Reviewed-by: Petr Pavlu Signed-off-by: Sami Tolvanen

modpost: Declare extra_warn with unused attribute

2026-03-30T05:45:34Z

A recent strengthening of -Wunused-but-set-variable (enabled with -Wall) in clang under a new subwarning, -Wunused-but-set-global, points out an unused static global variable in scripts/mod/modpost.c: scripts/mod/modpost.c:59:13: error: variable 'extra_warn' set but not used [-Werror,-Wunused-but-set-global] 59 | static bool extra_warn; | ^ This variable has been unused since commit 6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()") but that is expected, as there are currently no extra warnings at W=1 right now. Declare the variable with the unused attribute to make it clear to the compiler that this variable may be unused.

modpost: Amend ppc64 save/restfpr symnames for -Os build

2026-02-03T22:25:23Z

Building a size optimized ppc64 kernel (-Os), gcc emits more FP save/restore symbols, that the linker generates on demand into the .sfpr section. Explicitly allow-list those in scripts/mod/modpost.c, too. They are needed for the amdgpu in-kernel floating point support.

mcb: Add missing modpost build support

2025-12-27T19:48:01Z

mcb bus is not prepared to autoload client drivers with the data defined on the drivers' MODULE_DEVICE_TABLE. modpost cannot access to mcb_table_id inside MODULE_DEVICE_TABLE so the data declared inside is ignored. Add modpost build support for accessing to the mcb_table_id coded on device drivers' MODULE_DEVICE_TABLE.

modpost: drop '*_probe' from section check whitelist

2025-12-16T13:12:29Z

Several symbol patterns used to be whitelisted to allow drivers to refer to functions annotated with __devinit and __devexit, which have since been removed. Commit e1dc1bfe5b27 ("modpost: remove more symbol patterns from the section check whitelist") removed most of these patterns but left '*_probe' after a reported warning in an irqchip driver. Turns out that was indeed an incorrect reference which has now been fixed by commit 9b685058ca93 ("irqchip/qcom-irq-combiner: Fix section mismatch"). A recently added clocksource driver also relies on this suffix to suppress another valid warning, and that is being fixed separately. [1] Note that drivers with valid reasons for suppressing the warnings can use the __ref macros.

x86/asm: Remove ANNOTATE_DATA_SPECIAL usage

2025-12-03T15:53:19Z

Instead of manually annotating each __ex_table entry, just make the section mergeable and store the entry size in the ELF section header. Either way works for objtool create_fake_symbols(), this way produces cleaner code generation.

modpost: Ignore unresolved section bounds symbols

2025-10-14T21:45:22Z

In preparation for klp-build livepatch module creation tooling, suppress warnings for unresolved references to linker-generated __start_* and __stop_* section bounds symbols. These symbols are expected to be undefined when modpost runs, as they're created later by the linker. Cc: Masahiro Yamada Acked-by: Petr Mladek Tested-by: Joe Lawrence Signed-off-by: Josh Poimboeuf
