Linus Torvalds c235698355 cxl for 6.0
- Introduce a 'struct cxl_region' object with support for provisioning
   and assembling persistent memory regions.
 
 - Introduce alloc_free_mem_region() to accompany the existing
   request_free_mem_region() as a method to allocate physical memory
   capacity out of an existing resource.
 
 - Export insert_resource_expand_to_fit() for the CXL subsystem to
   late-publish CXL platform windows in iomem_resource.
 
 - Add a polled mode PCI DOE (Data Object Exchange) driver service and
   use it in cxl_pci to retrieve the CDAT (Coherent Device Attribute
   Table).
