  perf/x86/intel/pt: Fix crash with stop filters in single-range mode (2022-02-02 13:11:40 +0100)

----------------------------------------------------------------
perf/urgent contains 3 fixups:

 - Intel/PT: filters could crash the kernel

 - Intel: default disable the PMU for SMM, some new-ish EFI firmware has
   started using CPL3 and the PMU CPL filters don't discriminate against
   SMM, meaning that CPL3 (userspace only) events now also count EFI/SMM
   cycles.

 - Fixup for perf_event_attr::sig_data

(Peter Zijlstra)

      perf: Copy perf_event_attr::sig_data on modification
