Secure execution guest environments require an empty pinblob in all key generation and unwrap requests. Empty pinblobs are only available in EP11 API ordinal 6 or higher. Add an empty pinblob to key generation and unwrap requests, if the AP secure binding facility is available. In all other cases, stay with the empty pin tag (no pinblob) and the current API ordinals. The EP11 API ordinal also needs to be considered when the pkey module tries to figure out the list of eligible cards for key operations with protected keys in secure execution environment. These changes are transparent to userspace but required for running an secure execution guest with handling key generate and key derive (e.g. secure key to protected key) correct. Especially using EP11 secure keys with the kernel dm-crypt layer requires this patch.

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.
