Merge tag 'cxl-for-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull cxl updates from Dan Williams: "Compute Express Link (CXL) updates 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)" * tag 'cxl-for-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (74 commits) cxl/hdm: Fix skip allocations vs multiple pmem allocations cxl/region: Disallow region granularity != window granularity cxl/region: Fix x1 interleave to greater than x1 interleave routing cxl/region: Move HPA setup to cxl_region_attach() cxl/region: Fix decoder interleave programming Documentation: cxl: remove dangling kernel-doc reference cxl/region: describe targets and nr_targets members of cxl_region_params cxl/regions: add padding for cxl_rr_ep_add nested lists cxl/region: Fix IS_ERR() vs NULL check cxl/region: Fix region reference target accounting cxl/region: Fix region commit uninitialized variable warning cxl/region: Fix port setup uninitialized variable warnings cxl/region: Stop initializing interleave granularity cxl/hdm: Fix DPA reservation vs cxl_endpoint_decoder lifetime cxl/acpi: Minimize granularity for x1 interleaves cxl/region: Delete 'region' attribute from root decoders cxl/acpi: Autoload driver for 'cxl_acpi' test devices cxl/region: decrement ->nr_targets on error in cxl_region_attach() cxl/region: prevent underflow in ways_to_cxl() cxl/region: uninitialized variable in alloc_hpa() ...
