Linus Torvalds ae5ec8adb8 tsm for 6.16
- Add a general sysfs scheme for publishing "Measurement" values
   provided by the architecture's TEE Security Manager. Use it to publish
   TDX "Runtime Measurement Registers" ("RTMRs") that either maintain a
   hash of stored values (similar to a TPM PCR) or provide statically
   provisioned data.  These measurements are validated by a relying party.
 
 - Reorganize the drivers/virt/coco/ directory for "host" and "guest"
   shared infrastructure.
 
 - Fix a configfs-tsm-report unregister bug
 
 - With CONFIG_TSM_MEASUREMENTS joining CONFIG_TSM_REPORTS and in
   anticipation of more shared "TSM" infrastructure arriving, rename the
   maintainer entry to "TRUSTED SECURITY MODULE (TSM) INFRASTRUCTURE".

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.
