Subject: [PATCH 01/10] crypto: x86/aegis128 - Use RIP-relative addressing
Date: Sat, 8 Apr 2023 17:27:13 +0200 [thread overview]
Message-ID: <20230408152722.3975985-2-ardb@kernel.org> (raw)
In-Reply-To: <20230408152722.3975985-1-ardb@kernel.org>
Prefer RIP-relative addressing where possible, which removes the need
for boot time relocation fixups.
