- Fix support for platforms that do not enumerate every ACPI0016 (CXL
Host Bridge) in the CHBS (ACPI Host Bridge Structure).
- Introduce a common pci_find_dvsec_capability() helper, clean up open
coded implementations in various drivers.
- Add 'cxl_test' for regression testing CXL subsystem ABIs. 'cxl_test'
is a module built from tools/testing/cxl/ that mocks up a CXL topology
to augment the nascent support for emulation of CXL devices in QEMU.
- Convert libnvdimm to use the uuid API.
- Complete the definition of CXL namespace labels in libnvdimm.
- Tunnel libnvdimm label operations from nd_ioctl() back to the CXL
mailbox driver. Enable 'ndctl {read,write}-labels' for CXL.
- Continue to sort and refactor functionality into distinct driver and
core-infrastructure buckets. For example, mailbox handling is now a
generic core capability consumed by the PCI and cxl_test drivers.

Pull cxl updates from Dan Williams:
"More preparation and plumbing work in the CXL subsystem.
From an end user perspective the highlight here is lighting up the CXL
Persistent Memory related commands (label read / write) with the
generic ioctl() front-end in LIBNVDIMM.
Otherwise, the ability to instantiate new persistent and volatile
memory regions is still on track for v5.17.

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.
