[kbuild-all] [lkp] [+643 bytes kernel size regression] [i386-tinyconfig] [7229bb55d1] perf/x86/intel: Generic support for hardware TopDown metrics

FYI, we noticed a +643 bytes kernel size regression due to commit: commit: 7229bb55d1bb9b92d8c59f59fe51b18cb9bf6ff3 (perf/x86/intel: Generic support for hardware TopDown metrics) url: https://github.com/0day-ci/linux/commits/kan-liang-linux-intel-com/TopDow...
