Add key preparation code in case of selftest running to the phmac setkey function: As long as crypto_ahash_tested() returns with false, all setkey() invocations are assumed to carry sheer hmac clear key values and thus need some preparation to work with the phmac implementation. Thus it is possible to use the already available hmac test vectors implemented in the testmanager to test the phmac code. When crypto_ahash_tested() returns true (that is after larval state) the phmac code assumes the key material is a blob digestible by the pkey kernel module which converts the blob into a working key for the phmac code.

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.
