[PATCH v4 09/24] MIPS: ELF: Move relocation constants to UAPI

Thomas Weißschuh thomas.weissschuh at linutronix.de
Tue Aug 12 15:44:22 AEST 2025


These constants are useful for cross-platform userspace, for example to
process ELF files during kernel cross-compilation.

Move them from the kernel-private architecture-specific header to the UAPI.
