lib: zstd: Add kernel-specific API
This patch: - Moves `include/linux/zstd.h` -> `include/linux/zstd_lib.h` - Updates modified zstd headers to yearless copyright - Adds a new API in `include/linux/zstd.h` that is functionally equivalent to the in-use subset of the current API. Functions are renamed to avoid symbol collisions with zstd, to make it clear it is not the upstream zstd API, and to follow the kernel style guide. - Updates all callers to use the new API. There are no functional changes in this patch. Since there are no functional change, I felt it was okay to update all the callers in a single patch. Once the API is approved, the callers are mechanically changed. This patch is preparing for the 3rd patch in this series, which updates zstd to version 1.4.10. Since the upstream zstd API is no longer exposed to callers, the update can happen transparently.

cxl for v5.16
- Fix support for platforms that do not enumerate every ACPI0016 (CXL
Host Bridge) in the CHBS (ACPI Host Bridge Structure).
- Introduce a common pci_find_dvsec_capability() helper, clean up open
coded implementations in various drivers.
- Add 'cxl_test' for regression testing CXL subsystem ABIs. 'cxl_test'
is a module built from tools/testing/cxl/ that mocks up a CXL topology
to augment the nascent support for emulation of CXL devices in QEMU.
- Convert libnvdimm to use the uuid API.
- Complete the definition of CXL namespace labels in libnvdimm.
- Tunnel libnvdimm label operations from nd_ioctl() back to the CXL
mailbox driver. Enable 'ndctl {read,write}-labels' for CXL.
- Continue to sort and refactor functionality into distinct driver and
core-infrastructure buckets. For example, mailbox handling is now a
generic core capability consumed by the PCI and cxl_test drivers.

kgdb patches for 5.16
A single patch this cycle. We replace some open-coded routines to classify task states with the scheduler's own function to do this. Alongside the obvious benefits of removing funky code and aligning more exactly with the scheduler's task classification, this also fixes a long standing compiler warning by removing the open-coded routines that generated the warning.

core:
- Allow controlling synthesizing PERF_RECORD_ metadata events during record.
- perf.data reader prep work for multithreaded processing.
- Fix missing exclude_{host,guest} setting in PMUs that don't support it and
that were causing the feature detection code to disable it for all events,
even the ones in PMUs that support it.
- Fix the default use of precise events on AMD, that were always falling back
to non-precise because perf_event_attr.exclude_guest=1 was set and IBS does
not have filtering capability, refusing precise + exclude_guest.
- Add bitfield_swap() to handle branch_stack endian issue.
perf script:
- Show binary offsets for userspace addresses in callchains.

modules patches for 5.16-rc1
As requested by Jessica I'm stepping in to help with modules maintenance. This is my first pull request to you. I've collected only two patches for modules for the 5.16-rc1 merge window. These patches are from Shuah Khan as she debugged some corner case error with modules. The error messages are improved for elf_validity_check(). While doing this work a corner case fix was spotted on validate_section_offset() due to a possible overflow bug on 64-bit. The impact of this fix is low given this just limits module section headers placed within the 32-bit boundary, and we obviously don't have insane module sizes. Even if a specially crafted module is constructed later checks would invalidate the module right away. I've let this sit through 0-day testing since October 15th with no issues found.

perf build: Install libbpf headers locally when building
API headers from libbpf should not be accessed directly from the library's source directory. Instead, they should be exported with "make install_headers". Let's adjust perf's Makefile to install those headers locally when building libbpf. v2: - Fix $(LIBBPF_OUTPUT) when $(OUTPUT) is null. - Make sure the recipe for $(LIBBPF_OUTPUT) is not under a "ifdef".

perf symbols: Ignore $a/$d symbols for ARM modules
On anARM machine, kernel symbols from modules can be resolved to $a instead of printing the actual symbol name. Ignore symbols starting with "$" when building kallsyms rbtree. A sample stacktrace is shown as follows: c0f2e39c schedule_hrtimeout+0x14 ([kernel.kallsyms]) bf4a66d8 $a+0x78 ([test_module]) c0a4f5f4 kthread+0x15c ([kernel.kallsyms]) c0a001f8 ret_from_fork+0x14 ([kernel.kallsyms]) On an ARM machine, $a/$d symbols are used by the compiler to mark the beginning of code/data part in code section. These symbols are filtered out when linking vmlinux(see scripts/kallsyms.c ignored_prefixes), but are left on modules. So there are $a symbols in /proc/kallsyms which share the same addresses with the actual module symbols and confuses perf when resolving symbols. After this patch, the module symbol name is printed: c0f2e39c schedule_hrtimeout+0x14 ([kernel.kallsyms]) bf4a66d8 test_func+0x78 ([test_module]) c0a4f5f4 kthread+0x15c ([kernel.kallsyms]) c0a001f8 ret_from_fork+0x14 ([kernel.kallsyms]) Reviewed-by: James Clark <james.clark@arm.com> Signed-off-by: Lexi Shao <shaolexi@huawei.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Andrii Nakryiko <andrii@kernel.org> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jessica Yu <jeyu@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: John Fastabend <john.fastabend@gmail.com> Cc: KP Singh <kpsingh@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Martin KaFai Lau <kafai@fb.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Nathan Chancellor <natechancellor@gmail.com> Cc: Nick Desaulniers <ndesaulniers@google.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: QiuXi <qiuxi1@huawei.com> Cc: Song Liu <songliubraving@fb.com> Cc: Wangbing <wangbing6@huawei.com> Cc: Xiaoming Ni <nixiaoming@huawei.com> Cc: Yonghong Song <yhs@fb.com> Cc: bpf@vger.kernel.org Cc: clang-built-linux@googlegroups.com Link: https://lore.kernel.org/r/20211029065038.39449-2-shaolexi@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

perf evsel: Don't set exclude_guest by default
Perf tool sets exclude_guest by default while calling perf_event_open().
Because IBS does not have filtering capability, it always gets rejected
by IBS PMU driver and thus perf falls back to non-precise sampling. Fix
it by not setting exclude_guest by default on AMD.
Before:
$ sudo ./perf record -C 0 -vvv true |& grep precise
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
decreasing precise_ip by one (1)
precise_ip 1
decreasing precise_ip by one (0)
After:
$ sudo ./perf record -C 0 -vvv true |& grep precise
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
Committer notes:
Fixup init to zero for perf_env in older compilers:
arch/x86/util/evsel.c:15:26: error: missing field 'os_release' initializer [-Werror,-Wmissing-field-initializers]
struct perf_env env = {0};
^
Committer notes:
Namhyung remarked:
It'd be nice if it can cover explicit "-e cycles:pp" as well.
Ravi clarified:
For explicit :pp modifier, evsel->precise_max does not get set and thus perf
does not try with different attr->precise_ip values while exclude_guest set.
So no issue with explicit :pp:
$ sudo ./perf record -C 0 -e cycles:pp -vvv |& grep "precise_ip\|exclude_guest"
precise_ip 2
exclude_guest 1
precise_ip 2
exclude_guest 1
switching off exclude_guest, exclude_host
precise_ip 2
^C
Also, with :P modifier, evsel->precise_max gets set but exclude_guest does
not and thus :P also works fine:
$ sudo ./perf record -C 0 -e cycles:P -vvv |& grep "precise_ip\|exclude_guest"
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
^C

perf evsel: Fix missing exclude_{host,guest} setting
The current logic for the perf missing feature has a bug that it can
wrongly clear some modifiers like G or H. Actually some PMUs don't
support any filtering or exclusion while others do. But we check it as
a global feature.
For example, the cycles event can have 'G' modifier to enable it only in
the guest mode on x86. When you don't run any VMs it'll return 0.
# perf stat -a -e cycles:G sleep 1
Performance counter stats for 'system wide':
0 cycles:G
1.000721670 seconds time elapsed
But when it's used with other pmu events that don't support G modifier,
it'll be reset and return non-zero values.
# perf stat -a -e cycles:G,msr/tsc/ sleep 1
Performance counter stats for 'system wide':
538,029,960 cycles:G
16,924,010,738 msr/tsc/
1.001815327 seconds time elapsed
This is because of the missing feature detection logic being global.
Add a hashmap to set pmu-specific exclude_host/guest features.
Committer notes:
Fix 'perf test python' by adding a stub for evsel__find_pmu() in
tools/perf/util/python.c, document that it is used so far only for the
above reasons so that if anybody needs this in the python binding
usecases, we can revisit this.

Docs/admin-guide/mm/pagemap: wordsmith page flags descriptions
Some descriptions of page flags in 'pagemap.rst' are written in
assumption of none-rst, which respects every new line, as below:
7 - SLAB
page is managed by the SLAB/SLOB/SLUB/SLQB kernel memory allocator
When compound page is used, SLUB/SLQB will only set this flag on the head
Because rst ignores the new line between the first sentence and second
sentence, resulting html looks a little bit weird, as below.
7 - SLAB
page is managed by the SLAB/SLOB/SLUB/SLQB kernel memory allocator When
^
compound page is used, SLUB/SLQB will only set this flag on the head

This change makes it more natural and consistent with other parts in the

Docs/admin-guide/mm/damon/start: simplify the content
Information in 'TL; DR' section of 'Getting Started' is duplicated in other parts of the doc. It is also asking readers to visit the access pattern visualizations gallery web site to show the results of example visualization commands, while the users of the commands can use terminal output. To make the doc simple, this removes the duplicated 'TL; DR' section and replaces the visualization example commands with versions using terminal outputs.
