2013-05-24drivers/crypto/nx: Fixes for multiple races and issuesKent Yoder
Fixes a race on driver init with registering algorithms where the driver status flag wasn't being set before self testing started. Added the cra_alignmask field for CBC and ECB modes. Fixed a bug in GCM where AES block size was being used instead of authsize. Removed use of blkcipher_walk routines for scatterlist processing. Corner cases in the code prevent us from processing an entire scatterlist at a time and walking the buffers in block sized chunks turns out to be unecessary anyway. Fixed off-by-one error in saving off extra data in the sha code. Fixed accounting error for number of bytes processed in the sha code.

2013-01-03Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman
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.

2012-11-15powerpc+of: Add of node/property notification chain for adds and removesNathan Fontenot
This patch moves the notification chain for updates to the device tree from the powerpc/pseries code to the base OF code. This makes this functionality available to all architectures. Additionally the notification chain is updated to allow notifications for property add/remove/update. To make this work a pointer to a new struct (of_prop_reconfig) is passed to the routines in the notification chain. The of_prop_reconfig property contains a pointer to the node containing the property and a pointer to the property itself. In the case of property updates, the property pointer refers to the new property.

2012-09-05powerpc/crypto: Remove users of virt_to_abs() and phys_to_abs() in nx crypto ↵Michael Ellerman
driver phys_to_abs() is a nop, don't use it. virt_to_abs() is just a wrapper around __pa(), call __pa() directly. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
