[PATCH 04/11] crypto: caam: mark the hardware descriptor as cache line aligned

[Russell King <rmk+kernel@arm.linux.org.uk>]

Mark the hardware descriptor as being cache line aligned; on DMA
incoherent architectures, the hardware descriptor should sit in a
separate cache line from the CPU accessed data to avoid polluting
the caches.
