Linus Torvalds d1ac1a2b14 perf tools fixes and improvements for v6.2: 2nd batch
- Don't stop building perf if python setuptools isn't installed, just
   disable the affected perf feature.
 
 - Remove explicit reference to python 2.x devel files, that warning is
   about python-devel, no matter what version, being unavailable and thus
   disabling the linking with libpython.
 
 - Don't use -Werror=switch-enum when building the python support that
   handles libtraceevent enumerations, as there is no good way to test
   if some specific enum entry is available with the libtraceevent
   installed on the system.
 
 - Introduce 'perf lock contention' --type-filter and --lock-filter, to
   filter by lock type and lock name:
 
   $ sudo ./perf lock record -a -- ./perf bench sched messaging
 
   $ sudo ./perf lock contention -E 5 -Y spinlock
    contended  total wait   max wait  avg wait      type  caller

            8   118.13 us  20.51 us  14.77 us  spinlock  kthread+0xe5
 
 - Fix splitting CC into compiler and options when checking if a option
   is present in clang to build the python binding, needed in systems
   such as yocto that set CC to, e.g.: "gcc --sysroot=/a/b/c".
 
 - Refresh metris and events for Intel systems: alderlake.  alderlake-n,
   bonnell, broadwell, broadwellde, broadwellx, cascadelakex,
   elkhartlake, goldmont, goldmontplus, haswell, haswellx, icelake,
   icelakex, ivybridge, ivytown, jaketown, knightslanding, meteorlake,
   nehalemep, nehalemex, sandybridge, sapphirerapids, silvermont, skylake,
   skylakex, snowridgex, tigerlake, westmereep-dp, westmereep-sp,
   westmereex.
 
 - Add vendor events files (JSON) for AMD Zen 4, from sections 2.1.15.4
   "Core Performance Monitor Counters", 2.1.15.5 "L3 Cache Performance
   Monitor Counter"s and Section 7.1 "Fabric Performance Monitor Counter
   (PMC) Events" in the Processor Programming Reference (PPR) for AMD
   Family 19h Model 11h Revision B1 processors.
 
   This constitutes events which capture op dispatch, execution and
   retirement, branch prediction, L1 and L2 cache activity, TLB activity,
   L3 cache activity and data bandwidth for various links and interfaces in
   the Data Fabric.
 
 - Also, from the same PPR are metrics taken from Section 2.1.15.2
   "Performance Measurement", including pipeline utilization, which are
   new to Zen 4 processors and useful for finding performance bottlenecks
   by analyzing activity at different stages of the pipeline.
 
 - Greatly improve the 'srcline', 'srcline_from', 'srcline_to' and
   'srcfile' sort keys performance by postponing calling the external
   addr2line utility to the collapse phase of histogram bucketing.
 
 - Fix 'perf test' "all PMU test" to skip parametrized events, that
   requires setting up and are not supported by this test.
 
 - Update tools/ copies of kernel headers: features, disabled-features,
   fscrypt.h, i915_drm.h, msr-index.h, power pc syscall table and kvm.h.
 
 - Add .DELETE_ON_ERROR special Makefile target to clean up partially
   updated files on error.
 
 - Simplify the mksyscalltbl script for arm64 by avoiding to run the host
   compiler to create the syscall table, do it all just with the shell
   script.
 
 - Further fixes to honour quiet mode (-q).
