Linus Torvalds dd72945c43 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.

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.

  Summary:

   - 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.
