commit4549f7e5aaupstream. The geode AES driver is heavily broken because it stores per-request state in the transform context. So it will crash or produce the wrong result if used by any of the many places in the kernel that issue concurrent requests for the same transform object. This driver is also implemented using the deprecated blkcipher API, which makes it difficult to fix, and puts it among the drivers preventing that API from being removed. Convert this driver to use the skcipher API, and change it to not store per-request state in the transform context.

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.
