Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Make 'perf kmem' cope with the removal of some
   kmem:kmem_cache_alloc_node and kmem:kmalloc_node in the
   11e9734b ("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.

      perf auxtrace: Fix address filter duplicate symbol selection · cf129830
      Adrian Hunter authored 
      When a match has been made to the nth duplicate symbol, return
success not error.

Example:

  Before:

    $ cat file.c
    cat: file.c: No such file or directory
    $ cat file1.c
    #include <stdio.h>

    static void func(void)
    {
            printf("First func\n");
    }

    void other(void);

    int main()
    {
            func();
            other();
            return 0;
    }
    $ cat file2.c
    #include <stdio.h>

    static void func(void)
    {
            printf("Second func\n");
    }

    void other(void)
    {
            func();
    }

    $ gcc -Wall -Wextra -o test file1.c file2.c
    $ perf record -e intel_pt//u --filter 'filter func @ ./test' -- ./test
    Multiple symbols with name 'func'
    #1      0x1149  l       func
                    which is near           main
    #2      0x1179  l       func
                    which is near           other
    Disambiguate symbol name by inserting #n after the name e.g. func #2
    Or select a global symbol by inserting #0 or #g or #G
    Failed to parse address filter: 'filter func @ ./test'
    Filter format is: filter|start|stop|tracestop <start symbol or address> [/ <end symbol or size>] [@<file name>]
    Where multiple filters are separated by space or comma.
    $ perf record -e intel_pt//u --filter 'filter func #2 @ ./test' -- ./test
    Failed to parse address filter: 'filter func #2 @ ./test'
    Filter format is: filter|start|stop|tracestop <start symbol or address> [/ <end symbol or size>] [@<file name>]
    Where multiple filters are separated by space or comma.

  After:

    $ perf record -e intel_pt//u --filter 'filter func #2 @ ./test' -- ./test
    First func
    Second func
    [ perf record: Woken up 1 times to write data ]
    [ perf record: Captured and wrote 0.016 MB perf.data ]
    $ perf script --itrace=b -Ftime,flags,ip,sym,addr --ns
    1231062.526977619:   tr strt                               0 [unknown] =>     558495708179 func
    1231062.526977619:   tr end  call               558495708188 func =>     558495708050 _init
    1231062.526979286:   tr strt                               0 [unknown] =>     55849570818d func
    1231062.526979286:   tr end  return             55849570818f func =>     55849570819d other
