Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Fix and validate CPU map inputs in synthetic PERF_RECORD_STAT events
in 'perf stat'.
- Fix x86's arch__intr_reg_mask() for the hybrid platform.
- Address 'perf bench numa' compiler error on s390.
- Fix check for btf__load_from_kernel_by_id() in libbpf.
- Fix "all PMU test" 'perf test' to skip hv_24x7/hv_gpci tests on
powerpc.
- Fix session topology test to skip the test in guest environment.
- Skip BPF 'perf test' if clang is not present.
- Avoid shell test description infinite loop in 'perf test'.
- Fix Intel LBR callstack entries and nr print message.
