the landed patch sets are below. The .machine keyring, used for Machine Owner Keys (MOK), acquired the ability to store only CA enforced keys, and put rest to the .platform keyring, thus separating the code signing keys from the keys that are used to sign certificates. This essentially unlocks the use of the .machine keyring as a trust anchor for IMA. It is an opt-in feature, meaning that the additional contraints won't brick anyone who does not care about them. The 2nd feature is the enablement of interrupt based transactions with discrete TPM chips (tpm_tis). There was code for this existing but it never really worked so I consider this a new feature rather than a bug fix. Before the driver just falled back to the polling mode.

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.
