This patch backports several patches that went upstream into Herbert Xu's cryptodev-2.6 tree: crypto: Use zeroing memory allocator instead of allocator/memset crypto: crypto4xx - performance optimizations crypto: crypto4xx - convert to skcipher crypto: crypto4xx - avoid VLA use crypto: crypto4xx - add aes-ctr support crypto: crypto4xx - properly set IV after de- and encrypt crypto: crypto4xx - extend aead fallback checks crypto: crypto4xx - put temporary dst sg into request ctx The older, outstanding patches from 120-wxyz series have been upstreamed as well and therefore they have been reassigned to fit into the series.

Subject: [PATCH 1/8] crypto: Use zeroing memory allocator instead of
|
|
allocator/memset
|
|
|
|
Use dma_zalloc_coherent for allocating zeroed
|
|
memory and remove unnecessary memset function.
|
|
|
|
Done using Coccinelle.
|
|
Generated-by: scripts/coccinelle/api/alloc/kzalloc-simple.cocci
|

0-day tested with no failures.
