32bit has multiple values for its id registers, as extra properties were added to the CPUs. Some of these end up having long names, which exceed the fixed 48 character column that the sysreg awk script generates. For example, the ID_MMFR1_EL1.L1Hvd field has an encoding whose natural name would be 'invalidate Iside only'. Using this causes compile errors as the script generates the following: #define ID_MMFR1_EL1_L1Hvd_INVALIDATE_ISIDE_ONLYUL(0b0001) Add a few extra characters. Reviewed-by:

To convert the 32bit id registers to use the sysreg generation, they must first have a regular pattern, to match the symbols the script generates. Ensure symbols for the MVFR2_EL1 register use lower-case for feature names where the arm-arm does the same. No functional change. Signed-off-by:

Pull cxl fixes from Dan Williams: "Several fixes for CXL region creation crashes, leaks and failures. This is mainly fallout from the original implementation of dynamic CXL region creation (instantiate new physical memory pools) that arrived in v6.0-rc1. Given the theme of "failures in the presence of pass-through decoders" this also includes new regression test infrastructure for that case. Summary: - Fix region creation crash with pass-through decoders - Fix region creation crash when no decoder allocation fails - Fix region creation crash when scanning regions to enforce the increasing physical address order constraint that CXL mandates - Fix a memory leak for cxl_pmem_region objects, track 1:N instead of 1:1 memory-device-to-region associations. - Fix a memory leak for cxl_region objects when regions with active targets are deleted - Fix assignment of NUMA nodes to CXL regions by CFMWS (CXL Window) emulated proximity domains. - Fix region creation failure for switch attached devices downstream of a single-port host-bridge - Fix false positive memory leak of cxl_region objects by recycling recently used region ids rather than freeing them - Add regression test infrastructure for a pass-through decoder configuration - Fix some mailbox payload handling corner cases" * tag 'cxl-fixes-for-6.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/region: Recycle region ids cxl/region: Fix 'distance' calculation with passthrough ports tools/testing/cxl: Add a single-port host-bridge regression config tools/testing/cxl: Fix some error exits cxl/pmem: Fix cxl_pmem_region and cxl_memdev leak cxl/region: Fix cxl_region leak, cleanup targets at region delete cxl/region: Fix region HPA ordering validation cxl/pmem: Use size_add() against integer overflow cxl/region: Fix decoder allocation crash ACPI: NUMA: Add CXL CFMWS 'nodes' to the possible nodes set cxl/pmem: Fix failure to account for 8 byte header for writes to the device LSA. cxl/region: Fix null pointer dereference due to pass through decoder commit cxl/mbox: Add a check on input payload size -
