Subject: [PATCH 3.12 092/123] crypto: sparc - initialize blkcipher.ivsize

From: Dave Kleikamp <dave.kleikamp@...cle.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit a66d7f724a96d6fd279bfbd2ee488def6b081bea upstream.

Some of the crypto algorithms write to the initialization vector,
but no space has been allocated for it. This clobbers adjacent memory.
