Linus Torvalds 406254918b perf tools changes for v5.14:
Tools:
 
 - Add cgroup support for 'perf top' (-G).
 
 - Add support for KVM MSRs in 'perf kvm stat'
 
 - Support probes on init functions in 'perf probe', to support the
   bootconfig format.
 
 - Improve error reporting in 'perf probe'.
 
 - No need to synthesize BUILD_ID records in 'perf inject' if the MMAP2
   records have build ids already.
 
 - Allow toggling source code ('s' hotkey) in 'perf annotate' in all
   lines.
 
 - Add itrace options support to 'perf annotate'.
 
 - Support to custom DSO filters for 'perf script'.
 
 Hardware enablement:
 
 - Support the HYBRID_TOPOLOGY and HYBRID_CPU_PMU_CAPS features in the
   perf.data file header.
 
 - Support PMU prefix for mem-load and mem-store events, to support
   hybrid (BIG little) CPUs such as Intel's Alderlake.
 
 - Support hybrid CPUs in 'perf mem' and 'perf c2c'.
 
 Hardware tracing:
 
 - Intel PT now supports tracing KVM guests.
 
 - Timestamp improvements for ARM's Coresight.
 
 Build:
 
 - Add 'make -C tools/perf build-test' entries for libopencsd/CORESIGHT=1
   and libbpf/LIBBPF_DYNAMIC=1.
 
 - Use bison's --file-prefix-map option to avoid storing full paths when
   using O= in the perf build.
 
 Tests:
 
 - Improve the 'perf test' entries for libpfm4 and BPF counters.
 
 Misc:
 
 - Sync msr-index.h, mount.h, kvm headers with the kernel originals.
 
 - Add vendor events and metrics for Intel's Icelake Server & Client.

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.
