[PATCH v5 01/24] elf, uapi: Add a header for relocation constants

[Christophe Leroy (CS GROUP)]

Le 08/09/2026 à 08:33, Thomas Weißschuh a écrit :
> While the numeric constants for relocations are architecture specific,
> it is still useful to get access to them from other architectures.
> Also the definitions are useful for userspace in general.
> For example tools processing elf files during a kernel cross-compilation
> can make use of them.
> 
> Introduce a dedicated header for them, similar to the elf-em.h header.
> For now the header is empty but it will be filled step by step in
> upcomming commits.
