Subject: [PATCH 0/2] arm64: SHA1 using ARM v8 Crypto Extensions
Date: Thu, 6 Mar 2014 12:12:46 +0800 [thread overview]
Message-ID: <1394079168-27666-1-git-send-email-ard.biesheuvel@linaro.org> (raw)
This implements the SHA1 hash using ARM v8 Crypto Instructions.
Note that these patches depend on the modalias patch and NEON optimization
patches posted to the list over the past weeks.
The first patch is included for reference *only*. It implements emulation of
the SHA1 instructions in the kernel. (You need this patch to test the code if
your emulator or hardware has no support for Crypto Extensions)
