Merge tag 'perf-tools-fixes-for-v7.0-2-2026-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fix parsing 'overwrite' in command line event definitions in
   big-endian machines by writing correct union member

 - Fix finding default metric in 'perf stat'

 - Fix relative paths for including headers in 'perf kvm stat'

 - Sync header copies with the kernel sources: msr-index.h, kvm,
   build_bug.h
