- Refactor the DOE infrastructure (Data Object Exchange PCI-config-cycle
mailbox) to be a facility of the PCI core rather than the CXL core.
This is foundational for upcoming support for PCI device-attestation and
PCIe / CXL link encryption.
- Add support for retrieving and injecting poison for CXL memory
expanders. This enabling uses trace-events to convey CXL media error
records to user tooling. It includes translation of device-local
addresses (DPA) to system physical addresses (SPA) and their
corresponding CXL region.
- Fixes for decoder enumeration that missed v6.3-final
- Miscellaneous fixups

Pull compute express link updates from Dan Williams:
"DOE support is promoted from drivers/cxl/ to drivers/pci/ with Bjorn's
blessing, and the CXL core continues to mature its media management
capabilities with support for listing and injecting media errors. Some
late fixes that missed v6.3-final are also included:
- Refactor the DOE infrastructure (Data Object Exchange
PCI-config-cycle mailbox) to be a facility of the PCI core rather
than the CXL core.
This is foundational for upcoming support for PCI
device-attestation and PCIe / CXL link encryption.

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.
