Subject: [PATCH 3/3] crypto: x86 - add some missing SPDX headers
Date:   Tue,  6 Jun 2023 19:31:27 +0200
Message-Id: <20230606173127.4050254-4-ardb@kernel.org>
In-Reply-To: <20230606173127.4050254-1-ardb@kernel.org>
References: <20230606173127.4050254-1-ardb@kernel.org>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

Add some missing SPDX headers, and drop the associated boilerplate
license text to/from the x86 accelerated implementations of various
crypto algorithms.
