Pull cxl fixes from Dan Williams:
 "A collection of regression fixes, bug fixes, and some small cleanups
  to the Compute Express Link code.

  The regressions arrived in the v6.5 dev cycle and missed the v6.6
  merge window due to my personal absences this cycle. The most
  important fixes are for scenarios where the CXL subsystem fails to
  parse valid region configurations established by platform firmware.
  This is important because agreement between OS and BIOS on the CXL
  configuration is fundamental to implementing "OS native" error
  handling, i.e. address translation and component failure
  identification.

  Other important fixes are a driver load error when the BIOS lets the
  Linux PCI core handle AER events, but not CXL memory errors.

  The other fixex might have end user impact, but for now are only known
  to trigger in our test/emulation environment.

  Summary:

   - Fix multiple scenarios where platform firmware defined regions fail
     to be assembled by the CXL core.

   - Fix a spurious driver-load failure on platforms that enable OS
     native AER, but not OS native CXL error handling.

   - Fix a regression detecting "poison" commands when "security"
     commands are also defined.

   - Fix a cxl_test regression with the move to centralize CXL port
     register enumeration in the CXL core.

   - Miscellaneous small fixes and cleanups"

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct cxl_cxims_data.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

The cxl_test unit test environment models a CXL topology for
sysfs/user-ABI regression testing. It uses interface mocking via the
"--wrap=" linker option to redirect cxl_core routines that parse
hardware registers with versions that just publish objects, like
devm_cxl_enumerate_decoders().

Starting with:

Commit 19ab69a60e3b ("cxl/port: Store the port's Component Register mappings in struct cxl_port")

...port register enumeration is moved into devm_cxl_add_port(). This
conflicts with the "cxl_test avoids emulating registers stance" so
either the port code needs to be refactored (too violent), or modified
so that register enumeration is skipped on "fake" cxl_test ports
(annoying, but straightforward).

This conflict has happened previously and the "check for platform
device" workaround to avoid instrusive refactoring was deployed in those
scenarios. In general, refactoring should only benefit production code,
test code needs to remain minimally instrusive to the greatest extent
possible.

This was missed previously because it may sometimes just cause warning
messages to be emitted, but it can also cause test failures. The
backport to -stable is only nice to have for clean cxl_test runs.
