commit e8662a6a5f8f7f2cadc0edb934aef622d96ac3ee upstream.
The AEAD authenc key and IVs might be passed to us on stack. Copy it to
a slab buffer before mapping to gurantee proper DMA mapping.

crypto: ccree - remove special handling of chained sg2019-05-22T05:39:49ZGilad Ben-Yossefgilad@benyossef.com2019-04-18T13:38:48Zurn:sha1:5109c13347bdfbbb701ab7568581038516089370
commit c4b22bf51b815fb61a35a27fc847a88bc28ebb63 upstream.
We were handling chained scattergather lists with specialized code
needlessly as the regular sg APIs handle them just fine. The code
handling this also had an (unused) code path with a use-before-init
error, flagged by Coverity.
Remove all special handling of chained sg and leave their handling
to the regular sg APIs.

crypto: ccree - fix free of unallocated mlli buffer2019-01-25T10:41:51ZHadar Gathadar.gat@arm.com2019-01-15T13:43:13Zurn:sha1:a49411959ea6d4915a9fd2a7eb5ba220e6284e9a
In cc_unmap_aead_request(), call dma_pool_free() for mlli buffer only
if an item is allocated from the pool and not always if there is a
pool allocated.
This fixes a kernel panic when trying to free a non-allocated item.
