Integrate crypto_engine into CAAM, to make use of the engine queue. Add support for SKCIPHER algorithms. This is intended to be used for CAAM backlogging support. The requests, with backlog flag (e.g. from dm-crypt) will be listed into crypto-engine queue and processed by CAAM when free. This changes the return codes for enqueuing a request: -EINPROGRESS if OK, -EBUSY if request is backlogged (via crypto-engine), -ENOSPC if the queue is full, -EIO if it cannot map the caller's descriptor. The requests, with backlog flag, will be listed into crypto-engine queue and processed by CAAM when free. Only the backlog request are sent to crypto-engine since the others can be handled by CAAM, if free, especially since JR has up to 1024 entries (more than the 10 entries from crypto-engine).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
