2013-01-03Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman1-23/+23
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.

2012-09-15sparc64: Adjust crypto priorities.David S. Miller1-1/+1
Make the crypto opcode implementations have a higher priority than those provides by the ring buffer based Niagara crypto device. Also, several crypto opcode hashes were not setting the priority value at all. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-07-19n2_crypto: remove IRQF_SAMPLE_RANDOM which is now a no-opTheodore Ts'o1-2/+1
With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a no-op; interrupt randomness is now collected unconditionally in a very low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM flag was scheduled to be removed in 2009 on the feature-removal-schedule, so this patch is preparation for the final removal of this flag.

2012-01-13crypto: Add CRYPTO_ALG_KERN_DRIVER_ONLY flagNikos Mavrogiannopoulos1-2/+5
The added CRYPTO_ALG_KERN_DRIVER_ONLY indicates whether a cipher is only available via a kernel driver. If the cipher implementation might be available by using an instruction set or by porting the kernel code, then it must not be set.

2011-07-28n2_crypto: Attach on Niagara-T3.David S. Miller1-15/+18
A small modification was necessary since in the machine description for 'n2cp' and 'ncp' nodes, there no longer is an 'intr' property. That's OK because this property was always nothing more than an array of integers '1' ... 'nr_inos + 1' so we can just compute it in-place. Signed-off-by: David S. Miller <davem@davemloft.net>

2010-07-24of/platform: remove all of_bus_type and of_platform_bus_type referencesGrant Likely1-5/+5
Both of_bus_type and of_platform_bus_type are just #define aliases for the platform bus. This patch removes all references to them and switches to the of_register_platform_driver()/of_unregister_platform_driver() API for registering. Subsequent patches will convert each user of of_register_platform_driver() into plain platform_drivers without the of_platform_driver shim. At which point the of_register_platform_driver()/of_unregister_platform_driver() functions can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
