Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl tags/cxl-for-5.16
...to receive 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. More details in the tag message below. This has
appeared in linux-next with no reported issues.

ocxl: Use pci core's DVSEC functionality (2021-10-29 11:53:52 -0700)
----------------------------------------------------------------
cxl for v5.16
- 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.
----------------------------------------------------------------
