Subject: [PATCH v5 03/24] ARM: elf: Move relocation constants to UAPI
Date: Tue, 08 Sep 2026 08:33:37 +0200 [thread overview]
Message-ID: <20260908-vdso-absolute-reloc-v5-3-3a93791af1cf@linutronix.de> (raw)
In-Reply-To: <20260908-vdso-absolute-reloc-v5-0-3a93791af1cf@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.
One arm64 header is also changed as it duplicates an arm definition.
Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
