Subject: [PATCH v2 01/13] crypto: x86/aegis128 - Use RIP-relative addressing
Date: Wed, 12 Apr 2023 13:00:23 +0200 [thread overview]
Message-ID: <20230412110035.361447-2-ardb@kernel.org> (raw)
In-Reply-To: <20230412110035.361447-1-ardb@kernel.org>
Prefer RIP-relative addressing where possible, which removes the need
for boot time relocation fixups.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
