Algorithm registration is usually carried out during module init, where as little work as possible should be carried out. The SIMD code violated this rule by allocating a tfm, this then triggers a full test of the algorithm which may dead-lock in certain cases. SIMD is only allocating the tfm to get at the alg object, which is in fact already available as it is what we are registering. Use that directly and remove the crypto_alloc_tfm call. Also remove some obsolete and unused SIMD API. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
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 reStructuredText 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.
