Subject: [PATCH v4 15/24] powerpc/elf: Add 32-bit REL16 relocation definitions
Date: Tue, 12 Aug 2025 07:44:28 +0200 [thread overview]
Message-ID: <20250812-vdso-absolute-reloc-v4-15-61a8b615e5ec@linutronix.de> (raw)
In-Reply-To: <20250812-vdso-absolute-reloc-v4-0-61a8b615e5ec@linutronix.de>
These are used by userspace and are necessary for the vdsocheck tool.
They share the numbers with their 64-bit variants.
Also update the copy in tools/ so they can be used by vdsocheck.
Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
