Subject: [PATCH 3.10 33/46] powerpc: Add AT_HWCAP2 to indicate V.CRYPTO category support
Date: Fri, 4 Jul 2014 15:19:37 -0700 [thread overview]
Message-ID: <20140704221603.791748730@linuxfoundation.org> (raw)
In-Reply-To: <20140704221602.280733370@linuxfoundation.org>
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
commit dd58a092c4202f2bd490adab7285b3ff77f8e467 upstream.
The Vector Crypto category instructions are supported by current POWER8
chips, advertise them to userspace using a specific bit to properly
differentiate with chips of the same architecture level that might not
have them.
