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.

Yuan Kang 1acebad3d8 crypto: caam - faster aead implementation
Job descriptors only contain header and seq pointers.

Other commands are stored in separate shared descriptors
for encrypt, decrypt and givencrypt, stored as arrays
in caam_ctx.

This requires additional macros to create math commands
to calculate assoclen and cryptlen.

Kim Phillips 5228f0f79e crypto: talitos - ensure request ordering within a single tfm
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.

Josh Boyer c5697462ae crypto: crypto4xx - Perform read/modify/write on device control register
The Security function on the AMCC SoCs has multiple engines within a
single MMIO range.  The crypto driver currently enables the 3DES
functionality by doing a blind write to the device control register.
This can unintentionally disable other functions like the PKA or TRNG
when the driver is loaded.

Perform a read/modify/write to enable the 3DES function instead.

Dmitry Kasatkin 6c63db821d crypto: omap-sham - irq and dma handling changes
It could be a situation, that tasklet is executed twice because of
certain delay between dma callback and irq handler execution.
In that case, second tasklet execution could actually corrupt the data
of the new started dma transactions.

This patch improves tasklet logic and prevents above described cases.

Dmitry Kasatkin 6cb3ffe100 crypto: omap-sham - remove dedicated queue handling tasklet
Calling omap_sham_handle_queue from "done" tasklet should be done
after irq scheduled tasklet completes.
Having additional tasklet does not solve that issue because it might
be execute before.
So queue handling tasklet has been removed and functionality integrated
into single tasklet.

Some flags are changed in interrupt handlers and verified in the tasklet.
There might be a race condition when tasklet is interrupted or another

Atomic bitops functions are now used instead of bitmask operations.
