…/herbert/crypto-2.6

Pull crypto updates from Herbert Xu:
 "Algorithms:

   - Drop alignment requirement for data in aesni

   - Use synchronous seeding from the /dev/random in DRBG

   - Reseed nopr DRBGs every 5 minutes from /dev/random

   - Add KDF algorithms currently used by security/DH

   - Fix lack of entropy on some AMD CPUs with jitter RNG

  Drivers:

   - Add support for the D1 variant in sun8i-ce

   - Add SEV_INIT_EX support in ccp

   - PFVF support for GEN4 host driver in qat

   - Compression support for GEN4 devices in qat

   - Add cn10k random number generator support"

The KVM_SEV_INIT command is used by the hypervisor to initialize the SEV platform
context. In a typical workflow, this command should be the first command issued.

The firmware can be initialized either by using its own non-volatile storage or
the OS can manage the NV storage for the firmware using the module parameter
``init_ex_path``. The file specified by ``init_ex_path`` must exist. To create
a new NV storage file allocate the file with 32KB bytes of 0xFF as required by
the SEV spec.

Returns: 0 on success, -negative on error
