2011-08-10crypto: picoxcell - convert to platform ID tableJamie Iles
Use a platform ID table and a single platform_driver. It's neater and makes the device tree addition easier and more consistent. Rename the match values to be inline with what they'll be in the device tree bindings. There aren't any current in-tree users of the existing device names.

2011-08-03crypto: padlock-aes - Make module loading even quieter when hardware is missingJonathan Nieder
When loading aes via the module alias, a padlock module failing to load due to missing hardware is not particularly notable. With v2.6.27-rc1~1107^2~14 (crypto: padlock - Make module loading quieter when hardware isn't available, 2008-07-03), the padlock-aes module suppresses the relevant messages when the "quiet" flag is in use; but better to suppress this particular message completely, since the administrator can already distinguish such errors by the absence of a message indicating initialization failing or succeeding. This avoids occasional messages in syslog of the form padlock_aes: VIA PadLock not detected.

2011-07-28n2_crypto: Attach on Niagara-T3.David S. Miller
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>

2011-07-15crypto: talitos - ensure request ordering within a single tfmKim Phillips
Assign single target channel per tfm in talitos_cra_init instead of performing channel scheduling dynamically during the encryption request. This changes the talitos_submit interface to accept a new channel number argument. Without this, rapid bursts of misc. sized requests could make it possible for IPsec packets to be encrypted out-of-order, which would result in packet drops due to sequence numbers falling outside the anti-reply window on a peer gateway.

2011-05-19crypto: caam - add support for sha512 variants of existing AEAD algorithmsKim Phillips
In doing so, sha512 sized keys would not fit with the current descriptor inlining mechanism, so we now calculate whether keys should be referenced instead by pointers in the shared descriptor. also, use symbols for descriptor text lengths, and, ahem, unmap and free key i/o memory in cra_exit.

2011-05-19crypto: caam - fix decryption shared vs. non-shared key settingKim Phillips
Key sharing is enabled by default in the shared descriptor. Using CBC decrypt, AES has to alter the key in order to decrypt. During high traffic decryption rates, i.e, when sharing starts to take place, we need to use a different OPERATION option to tell AES that the key was already altered by the PRIOR descriptor - we need the following kind of logic: if ( shared ) operation where AES uses decryption key (DK=1) else operation where AES uses encryption key (DK=0) this patch implements this logic using a conditional and a non-conditional local jump within the decryption job descriptor.
