[ Upstream commit ebd9c2ae369a45bdd9f8615484db09be58fc242b ] During boot the Secure Boot Forbidden Signature Database, dbx, is loaded into the blacklist keyring. Systems booted with shim have an equivalent Forbidden Signature Database called mokx. Currently mokx is only used by shim and grub, the contents are ignored by the kernel. Add the ability to load mokx into the blacklist keyring during boot.

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.
