Subject: [PATCH v4 08/24] s390/elf: Move relocation constants to UAPI
Date: Tue, 12 Aug 2025 07:44:21 +0200 [thread overview]
Message-ID: <20250812-vdso-absolute-reloc-v4-8-61a8b615e5ec@linutronix.de> (raw)
In-Reply-To: <20250812-vdso-absolute-reloc-v4-0-61a8b615e5ec@linutronix.de>
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.
Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
