Subject: [PATCH 0/5] Avoid stack buffers in glue code of AVX implementations
Date: Sat, 20 Oct 2012 15:06:31 +0300 [thread overview]
Message-ID: <20121020120431.19422.17000.stgit@localhost6.localdomain6> (raw)
Patches modify AVX implementations so that they avoid using extra
stack memory. Stack is not needed since implementation store
blocks in registers.

Jussi Kivilinna (5):
crypto: x86/glue_helper - use le128 instead of u128 for CTR mode
crypto: cast6/avx - avoid using temporary stack buffers
crypto: twofish/avx - avoid using temporary stack buffers
crypto: serpent/avx - avoid using temporary stack buffers
crypto: cast5/avx - avoid using temporary stack buffers
