Linus Torvalds c47d122c5b perf tools fixes for v6.4:
- Fail graciously if BUILD_BPF_SKEL=1 is specified and clang isn't available.
 
 - Add empty 'struct rq' to 'perf lock contention' to satisfy libbpf 'runqueue'
   type verification. This feature is built only with BUILD_BPF_SKEL=1.
 
 - Make vmlinux.h use bpf.h and perf_event.h in source directory, not system
   ones that may be old and not have things like 'union perf_sample_weight'.
 
 - Add system include paths to BPF builds to pick things missing in the headers
   included by clang -target bpf.
 
 - Update various header copies with the kernel sources.
 
 - Change divide by zero and not supported events behavior to show 'nan'/'not
   counted' in 'perf stat' output. This happens when using things like
   'perf stat -M TopdownL2 true', involving JSON metrics.
 
 - Update no event/metric expectations affected by using JSON metrics in
   'perf stat -ddd' perf test.
 
 - Avoid segv with 'perf stat --topdown' for metrics without a group.
 
 - Do not assume which events may have a PMU name, allowing the logic to keep an
   AUX event group together. Makes this usecase work again:
 
     $ perf record --no-bpf-event -c 10 -e '{intel_pt//,tlb_flush.stlb_any/aux-sample-size=8192/pp}:u' -- sleep 0.1

 - Add a check for the above use case in 'perf test test_intel_pt'.
 
 - Fix build with refcount checking on arm64, it was still accessing fields that
   need to be wrapped so that the refcounted struct gets checked.
 
 - Fix contextid validation in ARM's CS-ETM, so that older kernels without that
   field can still be supported.
 
 - Skip unsupported aggregation for stat events found in perf.data files in 'perf script'.
 
 - Add stat test for record and script to check the previous problem.
 
 - Remove needless debuginfod queries from 'perf test java symbol', this was
   just making the test take a long time to complete.
 
 - Address python SafeConfigParser() deprecation warning in 'perf test attr'.
 
 - Fix __NR_execve undeclared on i386 'perf bench syscall' build error.
