Linus Torvalds e8f60cd7db perf tools fixes for v6.2: 2nd batch 
- Make 'perf kmem' cope with the removal of some kmem:kmem_cache_alloc_node and
   kmem:kmalloc_node in the 11e9734bcb ("mm/slab_common: unify NUMA and
   UMA version of tracepoints") commit, making sure it works with Linux >= 6.2 as well
   as with older kernels where those tracepoints are present.
 
 - Also make it handle the new "node" kmem:kmalloc and kmem:kmem_cache_alloc tracepoint
   field introduced in that same commit.
 
 - Fix hardware tracing PMU address filter duplicate symbol selection, that was
   preventing to match with static functions with the same name present in different
   object files.
 
 - Fix regression on what linux/types.h file gets used to build the "BPF prologue"
   'perf test' entry, the system one lacks the fmode_t definition used in this test,
   so provide that type in the test itself.
 
 - Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1. If the user asks for
   linking with the libbpf package provided by the distro, then it has to be >= 0.8.0.
   Using the libbpf supplied with the kernel would be a fallback in that case.
 
 - Fix the build when libbpf isn't available or explicitly disabled via NO_LIBBPF=1.
 
 - Don't try to install libtraceevent plugins as its not anymore in the kernel sources
   and will thus always fail.

README 

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.
