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.
