* crypto: atmel-aes - correct usage of dma_sync_* APILeilei Zhao2015-04-08
| | | | | | | | | | | The output buffer is used for CPU access, so the API should be dma_sync_single_for_cpu which makes the cache line invalid in order to reload the value in memory.

* crypto: atmel-aes - sync the buf used in DMA or CPULeilei Zhao2015-04-08
| | | | | | | | | | | | | | | | | | The input buffer and output buffer are mapped for DMA transfer in Atmel AES driver. But they are also be used by CPU when the requested crypt length is not bigger than the threshold value 16. The buffers will be cached in cache line when CPU accessed them. When DMA uses the buffers again, the memory can happened to be flushed by cache while DMA starts transfer. So using API dma_sync_single_for_device and dma_sync_single_for_cpu in DMA to ensure DMA coherence and CPU always access the correct value. This fix the issue that the encrypted result periodically goes wrong when doing performance test with OpenSSH.

* crypto: atmel-aes - initialize spinlock in probeLeilei Zhao2015-04-08
| | | | | | | | | | | Kernel will report "BUG: spinlock lockup suspected on CPU#0" when CONFIG_DEBUG_SPINLOCK is enabled in kernel config and the spinlock is used at the first time. It's caused by uninitialized spinlock, so just initialize it in probe.

* | Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman2013-01-03
|/ | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* crypto: drivers - remove cra_list initializationJussi Kivilinna2012-08-01
| | | | | | | | | | | | | | | | | | | Initialization of cra_list is currently mixed, most ciphers initialize this field and most shashes do not. Initialization however is not needed at all since cra_list is initialized/overwritten in __crypto_register_alg() with list_add(). Therefore perform cleanup to remove all unneeded initializations of this field in 'crypto/drivers/'.
