This patch implements the pkey_decrypt operation using the private key blob. The blob is first loaded into the TPM via tpm_loadkey2. Once the handle is obtained, tpm_unbind operation is used to decrypt the data on the TPM and the result is returned. The key loaded by tpm_loadkey2 is then evicted via tpm_flushspecific operation. This patch assumes that the SRK authorization is a well known 20-byte of zeros and the same holds for the key authorization of the provided key.

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.
