70177286e1 crypto: cast6-avx: use new optimized XTS code
Change cast6-avx to use the new XTS code, for smaller stack usage and small
boost to performance.

18be45270a crypto: x86/twofish-avx - use optimized XTS code
Change twofish-avx to use the new XTS code, for smaller stack usage and small
boost to performance.

tcrypt results, with Intel i5-2450M:
        enc     dec
16B     1.03x   1.02x
64B     0.91x   0.91x

1024B   1.12x   1.11x
8192B   1.12x   1.11x

Since XTS is practically always used with data blocks of size 512 bytes or
more, I chose to not make use of twofish-3way for block sized smaller than
128 bytes. This causes slower result in tcrypt for 64 bytes.

a05248ed2d crypto: x86 - add more optimized XTS-mode for serpent-avx
This patch adds AVX optimized XTS-mode helper functions/macros and converts
serpent-avx to use the new facilities. Benefits are slightly improved speed
and reduced stack usage as use of temporary IV-array is avoided.

This change is required for post SEC-5.0 devices which have RNG4.
Setting RDB in security configuration register allows CAAM to use the
"Random Data Buffer" to be filled by a single request. The Random Data
Buffer is large enough for ten packets to get their IVs from a single
request. If the Random Data Buffer is not enabled, then each IV causes a
separate request, and RNG4 hardware cannot keep up resulting in lower
IPSEC throughput if random IVs are used.

6150f3bc0b ARM: AT91SAM9G45: same platform data structure for all crypto peripherals
Only AES use DMA in AT91SAM9G45 (TDES and SHA use PDC).

However latest Atmel TDES and SHA IP releases use DMA instead of PDC.
  --> Atmel TDES and SHA drivers need DMA platform data for those IP releases.

Goal of this patch is to use the same platform data structure for all Atmel
crypto peripherals. This structure contains information about DMA interface.

This bool option can never be set to anything other than y.  So
let's just kill it.
