#     
#     Pull cxl updates from Dan Williams:
#      "Compute Express Link (CXL) updates for this cycle.
#     
#       The highlight is new driver-core infrastructure and CXL subsystem
#       changes for allowing lockdep to validate device_lock() usage. Thanks
#       to PeterZ for setting me straight on the current capabilities of the
#       lockdep API, and Greg acked it as well.
#     
#       On the CXL ACPI side this update adds support for CXL _OSC so that
#       platform firmware knows that it is safe to still grant Linux native
#       control of PCIe hotplug and error handling in the presence of CXL
#       devices. A circular dependency problem was discovered between suspend
#       and CXL memory for cases where the suspend image might be stored in
#       CXL memory where that image also contains the PCI register state to
#       restore to re-enable the device. Disable suspend for now until an
#       architecture is defined to clarify that conflict.
#     
#       Lastly a collection of reworks, fixes, and cleanups to the CXL
#       subsystem where support for snooping mailbox commands and properly
#       handling the "mem_enable" flow are the highlights.
#     
#       Summary:
#     
#        - Add driver-core infrastructure for lockdep validation of
#          device_lock(), and fixup a deadlock report that was previously
#          hidden behind the 'lockdep no validate' policy.
#     
#        - Add CXL _OSC support for claiming native control of CXL hotplug and
#          error handling.
#     
#        - Disable suspend in the presence of CXL memory unless and until a
#          protocol is identified for restoring PCI device context from memory
#          hosted on CXL PCI devices.
#     
#        - Add support for snooping CXL mailbox commands to protect against
#          inopportune changes, like set-partition with the 'immediate' flag
#          set.
#     
#        - Rework how the driver detects legacy CXL 1.1 configurations (CXL
#          DVSEC / 'mem_enable') before enabling new CXL 2.0 decode
#          configurations (CXL HDM Capability).
#     
#        - Miscellaneous cleanups and fixes from -next exposure"
