Merge branch 'for-7.0/cxl-init' into cxl-for-next
Merge in patches to support several patch series such as Soft Reserve
handling, type2 accelerator enabling, and LSA 2.1 labeling support.
Mainly addition of cxl_memdev_attach() to allow the memdev probe
to make a decision of proceed/fail depending success of CXL topology
enumeration.
dax/hmem, e820, resource: Defer Soft Reserved insertion until hmem is ready
cxl/mem: Introduce cxl_memdev_attach for CXL-dependent operation
cxl/mem: Drop @host argument to devm_cxl_add_memdev()
cxl/mem: Convert devm_cxl_add_memdev() to scope-based-cleanup
cxl/port: Arrange for always synchronous endpoint attach
cxl/mem: Arrange for always-synchronous memdev attach
cxl/mem: Fix devm_cxl_memdev_edac_release() confusion
