Subject: [PATCH v4 01/24] elf, uapi: Add a header for relocation constants
Date: Tue, 12 Aug 2025 07:44:14 +0200 [thread overview]
Message-ID: <20250812-vdso-absolute-reloc-v4-1-61a8b615e5ec@linutronix.de> (raw)
In-Reply-To: <20250812-vdso-absolute-reloc-v4-0-61a8b615e5ec@linutronix.de>
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.
