[PATCH] Using alloc_coherent for caam job rings

2012-06-26 Thread Bharat Bhushan
From: Bharat Bhushan The caam job rings (input/output job ring) are allocated using dma_map_single(). These job rings can be visualized as the ring buffers in which the jobs are en-queued/de-queued. The s/w enqueues the jobs in input job ring which h/w dequeues and after processing it copies the
