Subject: [PATCH v4 04/24] arm64: elf: Move relocation constants to UAPI
Date: Tue, 12 Aug 2025 07:44:17 +0200	[thread overview]
Message-ID: <20250812-vdso-absolute-reloc-v4-4-61a8b615e5ec@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>
