[GIT PULL] Compute Express Link update for v5.15

[Dan Williams <dan.j.williams@intel.com>]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl tags/cxl-for-5.15

...to receive the cxl update for v5.15. This branch experienced some
fallout from some "just in time" review and the -Werror change. Rather
than rebase patches at the last moment the branch was simply rewound
to a stable point and the rest will wait for v5.16. Save for the top 6
fixes this has been in -next for several releases with no reported
issues (beyond the ones that caused the branch to be rewound), and the
fixes have appeared in at least one -next release.

Please pull, thanks,
Dan

  cxl/registers: Fix Documentation warning (2021-09-07 11:39:02 -0700)

----------------------------------------------------------------
cxl for v5.15

- Fix detection of CXL host bridges to filter out disabled ACPI0016
  devices in the ACPI DSDT.

- Fix kernel lockdown integration to disable raw commands when raw PCI
  access is disabled.

- Fix a broken debug message.

- Add support for "Get Partition Info". I.e. enumerate the split between
  volatile and persistent capacity on bi-modal CXL memory expanders.

- Re-factor the core by subject area. This is a work in progress.

- Prepare libnvdimm to understand CXL labels in addition to EFI labels.
  This is a work in progress.
