Patch series "Some minor cleanup patches resent". The first three patches trivial clean up patches. And for the patch "kexec: replace crash_mem_range with range", I got a ibm-p9wr ppc64le system to test, it works well. This patch (of 4): elfcorehdr_alloc() allocates a memory chunk for elfcorehdr_addr with kzalloc(). If is_vmcore_usable() returns false, elfcorehdr_addr is a predefined value. If parse_crash_elf_headers() gets some error and returns a negetive value, the elfcorehdr_addr should be released with elfcorehdr_free(). Fix it by calling elfcorehdr_free() when parse_crash_elf_headers() fails.

Statistically, in a large deployment regular segfaults may indicate a CPU issue. Currently, it is not possible to find out what CPU the segfault happened on. There are at least two attempts to improve segfault logging with this regard, but they do not help in case the logs rotate. Hence, lets make sure it is possible to permanently record a CPU the task ran on using a new core_pattern specifier.

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 -
