mm/page_owner: add MR_NEVER to enum migrate_reason and use it for last_migrate_reason

2026-07-03T06:26:51+00:00

The last_migrate_reason field uses -1 as a sentinel value to mean "no migration has happened". Replace the four bare -1 occurrences by adding a proper MR_NEVER member to enum migrate_reason, defining a corresponding "never_migrated" string in the MIGRATE_REASON trace macro, and updating the GDB page_owner script to use MR_NEVER instead of the hardcoded -1 so that lx-dump-page-owner does not incorrectly report unmigrated pages as migrated. No functional change.

scripts/sorttable: Handle RISC-V patchable ftrace entries

2026-06-25T19:15:03+00:00

RISC-V uses -fpatchable-function-entry=8,4 when the compressed ISA is enabled and -fpatchable-function-entry=4,2 otherwise. In both cases, the patchable NOP area starts 8 bytes before the function symbol address. The __mcount_loc entries therefore point at the patchable NOP area associated with a function, while nm reports the function symbol at the entry address used for the function range check. After RISC-V selected HAVE_BUILDTIME_MCOUNT_SORT, sorttable started applying that range check at build time. Without allowing entries just before the reported function address, the mcount sorter treats valid RISC-V ftrace callsites as invalid weak-function entries and writes them back as zero. The resulting kernel boots with no ftrace entries, breaking dynamic ftrace and users such as livepatch. The failure is silent during the final link because zeroing weak-function entries is an expected sorttable operation. At boot, those zero entries are skipped by ftrace_process_locs(), so the only obvious symptom is that the vmlinux ftrace table has lost valid callsites and ftrace users cannot attach to them. CONFIG_FTRACE_SORT_STARTUP_TEST also reports the table as sorted in this state: it only checks that the __mcount_loc entries are in ascending order, which a fully zeroed table trivially satisfies. The original commit relied on this check and did not see the regression. On an affected RISC-V QEMU boot with both CONFIG_FTRACE_SORT_STARTUP_TEST and CONFIG_FTRACE_STARTUP_TEST enabled, the sort check still passes while ftrace reports zero usable entries and the early selftests fail: [ 0.000000] ftrace section at ffffffff8101da98 sorted properly [ 0.000000] ftrace: allocating 0 entries in 128 pages [ 0.054999] Testing tracer function: .. no entries found ..FAILED! [ 0.172407] tracer: function failed selftest, disabling [ 0.178186] Failed to init function_graph tracer, init returned -19 Handle RISC-V like arm64 for the function-range check and allow patchable entries up to 8 bytes before the function address. With this fix, a RISC-V QEMU smoke boot with ftrace startup tests shows the vmlinux ftrace table is populated and dynamic ftrace still works: [ 0.000000] ftrace: allocating 46749 entries in 184 pages [ 0.051115] Testing tracer function: PASSED [ 1.283782] Testing dynamic ftrace: PASSED [ 6.275456] Testing tracer function_graph: PASSED Fixes: 0ca1724b56af ("riscv: ftrace: select HAVE_BUILDTIME_MCOUNT_SORT") Suggested-by: Steven Rostedt (Google) Reviewed-by: Steven Rostedt Reviewed-by: Shuai Xue Reviewed-by: Chen Pei Link: https://lore.kernel.org/all/20260527113028.4b21a5de@fedora/ Signed-off-by: Wang Han Reviewed-by: Martin Kaiser Link: https://patch.msgid.link/20260609063002.3943001-1-wanghan@linux.alibaba.com Signed-off-by: Paul Walmsley

Pull SPDX updates from Greg KH: "Here is a "big" set of SPDX-like patches for 7.2-rc1. It is the addition of the ability for the kernel build process to generate a Software Bill of Materials (SBOM) in the SPDX format, that matches up exactly with just the files that are actually built for the specific kernel image generated. To generate a sbom, after the kernel has been built, just do: make sbom and marvel at the JSON file that is generated... This is needed by users for environments in which a SBOM is required (medical, automotive, anything shipped in the EU, etc.) and cuts down by a massive size the "naive" SBOM solution that many vendors have done by just including _all_ of the kernel files in the resulting document. This result is still a giant JSON file, that I am told parses properly, so we just have to trust that it is properly inclusive as attempting to parse that thing by hand is impossible. The scripts here are self-contained python scripts, no additional libraries or tools to create the SBOM are needed, which is important for many build systems. Overall it's just a bit over 4000 lines of "simple" python code, the most complex part is the regex matching lines, but those are nothing compared to what we maintain in scripts/checkpatch.pl today... The various parts where the tool touches the kbuild subsystem have been acked by the kbuild maintainer, so all should be good here. All of these patches have been in linux-next for weeks with no reported problems" * tag 'spdx-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: scripts/sbom: add unit tests for SPDX-License-Identifier parsing scripts/sbom: add unit tests for command parsers scripts/sbom: add SPDX build graph scripts/sbom: add SPDX source graph scripts/sbom: add SPDX output graph scripts/sbom: collect file metadata scripts/sbom: add shared SPDX elements scripts/sbom: add JSON-LD serialization scripts/sbom: add SPDX classes scripts/sbom: add additional dependency sources for cmd graph scripts/sbom: add cmd graph generation scripts/sbom: add command parsers scripts/sbom: setup sbom logging scripts/sbom: integrate script in make process scripts/sbom: add documentation

The `-> Result<(), impl core::fmt::Debug>` string is generated by rustdoc and by adding "::" into the string it no longer finds anything, making the line useless. Remove the "::" in the pattern.
