Linus Torvalds 9597f088c9 perf tools fixes for v6.0: 4th batch
- Fix polling of system-wide events related to mixing per-cpu and per-thread
   events.
 
 - Do not check if /proc/modules is unchanged when copying /proc/kcore,
   that doesn't get in the way of post processing analysis.
 
 - Include program header in ELF files generated for JIT files, so that they can
   be opened by tools using elfutils libraries.
 
 - Enter namespaces when synthesizing build-ids.
 
 - Fix some bugs related to a recent cpu_map overhaul where we should be
   using an index and not the cpu number.
 
 - Fix BPF program ELF section name, using the naming expected by libbpf when
   using BPF counters in 'perf stat'.
 
 - Add a new test for perf stat cgroup BPF counter.
 
 - Adjust check on 'perf test wp' for older kernels, where the
   PERF_EVENT_IOC_MODIFY_ATTRIBUTES ioctl isn't supported.
 
 - Sync x86 cpufeatures with the kernel sources, no changes in tooling.

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.
