Merge tag 'perf-tools-fixes-for-v6.13-2024-12-12' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools fixes from Namhyung Kim:
 "A set of random fixes for this cycle.

  perf record:
   - Fix build-id event size calculation in perf record
   - Fix perf record -C/--cpu option on hybrid systems
   - Fix perf mem record with precise-ip on SapphireRapids

  perf test:
   - Refresh hwmon directory before reading the test files
   - Make sure system_tsc_freq event is tested on x86 only

  Others:
   - Usual header file sync
   - Fix undefined behavior in perf ftrace profile
   - Properly initialize a return variable in perf probe"
