Pull perf tools fixes from Arnaldo Carvalho de Melo:
 "Perf tool fixes:

   - Fix wrong skipping for per-die aggregation in 'perf stat'.

   - Fix race in signal handling on large core count machines, setting
     up signal handlers earlier.

   - Fix -F for branch & mem modes in 'perf report'.

   - Fix the condition checks for max number of NUMA nodes in 'perf
     bench numa'.

   - Fix crash in 'perf diff' error path.

   - Fix filtering of empty build-ids in 'perf archive'.

   - Ensure read cmdlines from libtraceevent are null terminated.

  Recent regressions:

   - Fix control fifo permissions in 'perf daemon'.

   - Fix 'perf daemon' compile error with ASAN.

   - Fix running 'perf daemon' test for non root user.

   - Fix PERF_SAMPLE_WEIGHT_STRUCT 'perf test' failure on non-x86
     arches.

   - Fix event's PMU name parsing related to new drm/i915/gt
     software-gt-awake-time event.

  Fixes from compiler instrumentation:

   - Fix leaks in 'perf test' entries, found using ASAN.

   - Fix use-after-free when 'perf stat -r' option is used.

  Arch specific:

   - Fix bitmap for option om ARM's CS-ETM.

  Documentation:

   - Fix documentation of verbose options.

  Build:

   - Clean 'generated' directory used for creating the syscall table on
     x86.

   - Fix ccache usage in $(CC) when generating arch errno table.

   - Cast (struct timeval).tv_sec when printing, fixing the build with
     MUSL libc.

   - Tighten snprintf() string precision to pass gcc check on some
     32-bit arches.

   - Update UAPI copies from the kernel sources.

   - Fix regression on feature detection 'make clean' target"
