This patch adds virtual address support to ahash. Virtual addresses were previously only supported through shash. The user may choose to use virtual addresses with ahash by calling ahash_request_set_virt instead of ahash_request_set_crypt. The API will take care of translating this to an SG list if necessary, unless the algorithm declares that it supports chaining. Therefore in order for an ahash algorithm to support chaining, it must also support virtual addresses directly. 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.
