Subject: [PATCH 04/10] crypto: x86/camellia - Use RIP-relative addressing
Date:   Sat,  8 Apr 2023 17:27:16 +0200
Message-Id: <20230408152722.3975985-5-ardb@kernel.org>
In-Reply-To: <20230408152722.3975985-1-ardb@kernel.org>
References: <20230408152722.3975985-1-ardb@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Prefer RIP-relative addressing where possible, which removes the need
for boot time relocation fixups.
