Hi Community,
I use an Atom 330 (Dual-Core) ION based system as work station at home.
The rootfs is crypted with cryptsetup/luks.
As the Atom 330 is rather weak in cryptographic speed and I realized that a
single
blockdevice is always handled by onl

This adds support for Marvell's Cryptographic Engines and Security
Accelerator (CESA) which can be found on a few SoC.
Tested with dm-crypt.

Remove the dedicated GHASH implementation in GCM, and uses the GHASH
digest algorithm instead. This will make GCM uses hardware accelerated
GHASH implementation automatically if available.
ahash instead of shash interface is used, because some hardware

PCLMULQDQ is used to accelerate the most time-consuming part of GHASH,

cryptd_alloc_ahash() will allocate a cryptd-ed ahash for specified
algorithm name. The new allocated one is guaranteed to be cryptd-ed
ahash, so the shash underlying can be gotten via cryptd_ahash_child().

GHASH is implemented as a shash algorithm. The actual implementation
is copied from gcm.c. This makes it possible to add
architecture/hardware accelerated GHASH implementation.
