Pull perf tool fixes from Arnaldo Carvalho de Melo: - Fix some aspects of building with an older (than the one in the kernel sources) libbpf present in a distro, when building with LIBBPF_DYNAMIC=1. - Fix errno setting races with event_fd and the signal handler in 'perf record'. - Fix Power10 hv-24x7 metric events when some events may have a zero count based on system configuration. - Do not fail Intel-PT misc test w/o libpython, just skip it. - Fix incorrect arm64 Hisi hip08 L3 metrics (IF_BP_MISP_BR_RET, IF_BP_MISP_BR_RET, IF_BP_MISP_BR_BL) due to mistakes in the documentation used to generate the JSON files for these metrics. - Fix auxtrace (Intel PT, ARM Coresight) address filter symbol name match for modules, we need to skip the module name. - Sync copies of files with the kernel sources, including ppc syscall tables and assorted headers, some resulting in tools being able to decode new network protocols (IPPROTO_L2TP) and statx masks (STATX_DIOALIGN). - Fix PMU name pai_crypto in the vendor events file (JSON) for s390. - Fix man page build wrt perf-arm-coresight.txt as the build process assumes files starting with 'perf-' are man pages, and this file isn't one. * tag 'perf-tools-fixes-for-v6.1-2022-10-26' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf vendor events arm64: Fix incorrect Hisi hip08 L3 metrics perf auxtrace: Fix address filter symbol name match for modules tools headers UAPI: Sync linux/perf_event.h with the kernel sources tools headers cpufeatures: Sync with the kernel sources tools headers uapi: Sync linux/stat.h with the kernel sources tools include UAPI: Sync sound/asound.h copy with the kernel sources tools headers uapi: Update linux/in.h copy tools headers: Update the copy of x86's memcpy_64.S used in 'perf bench' tools headers arm64: Sync arm64's cputype.h with the kernel sources perf test: Do not fail Intel-PT misc test w/o libpython perf list: Fix PMU name pai_crypto in perf list on s390 perf record: Fix event fd races perf bpf: Fix build with libbpf 0.7.0 by checking if bpf_program__set_insns() is available perf bpf: Fix build with libbpf 0.7.0 by adding prototype for bpf_load_program() perf vendor events power10: Fix hv-24x7 metric events perf docs: Fix man page build wrt perf-arm-coresight.txt tools headers UAPI: Sync powerpc syscall tables with the kernel sources
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
