Linus Torvalds 45b2e5ad68 perf tools changes for v5.19: 3rd batch
- Synthesize task events for pre-existing threads when using 'perf lock --threads',
   as we need to show task names.
 
 - Fix unwinding with ld.lld (>= version 10.0) linked objects, where
   .eh_frame_hdr and .text are in different PT_LOAD program headers, which makes
   perf record --call-graph dwarf fail with such obkects.
 
 - Check if 'perf record' hangs in the ARM SPE (Statistical Profiling Extensions)
   'perf test' entry when recording a workload with forks.
 
 - Trace physical address for Arm SPE events, needed for 'perf c2c' to locate
   the memory node for samples.
 
 - Fix sorting in percent_rmt_hitm_cmp() in 'perf c2c'.
 
 - Further support for Intel hybrid systems in the evlist and 'perf record' code.
 
 - Update IBM s/390 vendor event JSON tables.
 
 - Add metrics (JSON) for Intel Sapphirerapids.
 
 - Update metrics for Intel Alderlake.
 
 - Correct typo of sysf 'event_source' directory in the documentation.

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.
