Pull perf tools updates from Namhyung Kim:
 "Build:

   - Build each directory as a library so that depedency check for the
     python extension module can be automatic

   - Use pkg-config to check libtraceevent and libtracefs

  perf sched:

   - Add --task-name and --fuzzy-name options for `perf sched map`

     It focuses on selected tasks only by removing unrelated tasks in
     the output. It matches the task comm with the given string and the
     --fuzzy-name option allows the partial matching:

       $ sudo perf sched record -a sleep 1

       $ sudo perf sched map --task-name kworker --fuzzy-name

   - Fix -r/--repeat option of perf sched replay

     The documentation said -1 will work as infinity but it didn't
     accept the value. Update the code and document to use 0 instead

   - Fix perf sched timehist to account the delay time for preempted
     tasks

  Perf event filtering:

   - perf top gained filtering support on regular events using BPF like
     perf record. Previously it was able to use it for tracepoints only

   - The BPF filter now supports filtering by UID/GID. This should be
     preferred than -u <UID> option as it's racy to scan /proc to check
     tasks for the user and fails to open an event for the task if it's
     already gone

       $ sudo perf top -e cycles --filter "uid == $(id -u)"

  perf report:

   - Skip dummy events in the group output by default. The --skip-empty
     option controls display of empty events without samples. But perf
     report can force display all events in a group

     In this case, auto-added a dummy event (for a system-wide record)
     ends up in the output. Now it can skip those empty events even in
     the group display mode

     To preserve the old behavior, run this:

       $ perf report --group --no-skip-empty

  perf stat:

   - Choose the most disaggregate option when multiple aggregation
     options are given. It used to pick the last option in the command
     line but it can be confusing and not consistent. Now it'll choose
     the smallest unit

     For example, it'd aggregate the result per-core when the user gave
     both --per-socket and --per-core options at the same time

  Internals:

   - Fix `perf bench` when some CPUs are offline

   - Fix handling of JIT symbol mappings to accept "/tmp/perf-${PID}.map
     patterns only so that it can not be confused by other /tmp/perf-*
     files

   - Many improvements and fixes for `perf test`

  Others:

   - Support some new instructions for Intel-PT

   - Fix syscall ID mapping in perf trace

   - Document AMD IBS PMU usages

   - Change `perf lock info` to show map and thread info by default

  Vendor JSON events:

   - Update Intel events and metrics

   - Add i.MX9[35] DDR metrics"
