The MAC hash key might be passed to us on stack. Copy it to
a slab buffer before mapping to gurantee proper DMA mapping.

crypto: ccree - use correct internal state sizes for export2019-04-25T07:38:15+00:00Gilad Ben-Yossefgilad@benyossef.com2019-04-18T13:39:02+00:00urn:sha1:f3df82b468f00cca241d96ee3697c9a5e7fb6bd0
We were computing the size of the import buffer based on the digest size
but the 318 and 224 byte variants use 512 and 256 bytes internal state
sizes respectfully, thus causing the import buffer to overrun.
Fix it by using the right sizes.

crypto: ccree - fix backlog notifications2019-04-25T07:38:14+00:00Gilad Ben-Yossefgilad@benyossef.com2019-04-18T13:38:46+00:00urn:sha1:a108f9311c01271bccad45d321cf9ddfac852c4b
We were doing backlog notification callbacks via a cipher/hash/aead
request structure cast to the base structure, which may or may not
work based on how the structure is laid in memory and is not safe.
Fix it by delegating the backlog notification to the appropriate
internal callbacks which are type aware.
