This was broken by commit 7759995c75 (yes,
myself). The basic problem here is since the digest state is only saved
after the last chunk, the state array is only valid when handling the
first chunk of the next buffer. Broken since linux-3.0.

Part of the include cleanups means that the implicit

fix things up in advance.

The CDPR (Current Descriptor Pointer Register) can be unreliable
when trying to locate an offending descriptor. Handle that case by
(a) not OOPSing, and (b) reverting to the machine internal copy of
the descriptor header in order to report the correct execution unit
error.
Note: printing all execution units' ISRs is not effective because it
results in an internal time out (ITO) error and the EU resetting its
ISR value (at least when specifying an invalid key length on an SEC
2.2/MPC8313E).

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.

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

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.

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.
