Merge tag 'cxl-for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxlPull CXL updates from Dave Jiang: "This includes the remaining patches to complete the basic support for CXL type2 (accelerators) drivers by the CXL core. A set of unit testing support to catch regressions for the CXL core type2 exported functions has also been added. The actual CXL type 2 driver support for the AMD Solarflare NIC driver has been picked up by net-dev. A set of preparatory patches has been picked up from the CXL port error handling series in order to reduce the number of patches in that series for review. The rest of that series is getting close to be merged but was not ready for the 7.3 merge window. There are also a number of misc patches and a large number of bug fixes against pre-existing issues flagged by sashiko reviews as contributors post new patches on the mailing list. We will continue to work through the sashiko raised issues as they show up."* tag 'cxl-for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (35 commits) cxl/Documentation: Spell out globbed sysfs attribute names cxl: Rename find_cxl_port() to find_cxl_port_by_dport() cxl: Tighten CPER kfifo registration API and symbol visibility acpi/apei/ghes: Use raw_spinlock_t for CXL CPER work locks cxl/ras: Fix cxl_rch_get_aer_severity() wrong severity register cxl/ras: Fix cxl_rch_get_aer_info() out-of-bounds AER register read cxl/test: Assign one mock memdev a full-width serial number cxl/core: Format the memdev serial number as unsigned in TP_printk cxl/pmem: Format the nvdimm serial number as unsigned decimal cxl: Use %pe to print error pointers cxl/region: Use __free(put_device) in find_pos_and_ways() cxl/region: Fix use-after-free in find_pos_and_ways() error path cxl: Deny Features commands on the RAW mailbox path cxl/features: Clamp Get Feature output size to the remaining buffer cxl/features: Reject Set Features output buffer smaller than the header cxl/features: Reject Get Feature count larger than the output buffer cxl/port: Restart port enumeration when a sibling adds the dport first cxl/features: Serialize multi-part Get/Set Feature transfers cxl/pci: Honor -EPROBE_DEFER from component register setup cxl/mbox: Break poison list loop on an empty payload ...
