David S. Miller 1080362425 sparc64: Adjust crypto priorities.
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.

Theodore Ts'o 9751bfd1c9 n2_crypto: remove IRQF_SAMPLE_RANDOM which is now a no-op
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.

Nikos Mavrogiannopoulos d912bb7677 crypto: Add CRYPTO_ALG_KERN_DRIVER_ONLY flag
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.

David S. Miller eb7caf3595 n2_crypto: Attach on Niagara-T3.
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.

Grant Likely 2dc1158137 of/device: Replace struct of_device with struct platform_device
of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

Grant Likely 1ab1d63a85 of/platform: remove all of_bus_type and of_platform_bus_type references
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.

So instead, have a single n2_hash_async_digest() and use an
n2_ahash_alg container that provides the parameters.

David S. Miller c9aa55e527 n2_crypto: Plumb fallback ahash requests properly.
Do this by putting the async fallback request at the end of an n2
specific ahash request context, then properly adjusting the request
private size in our ahash ->cra_init().

We also need to put the writable state bits into the n2 request
private instead of the n2 cra_ctx.
