Linus Torvalds 191aaf6cc4 Misc fixes:
- Fix the NMI watchdog on ancient Intel CPUs
 
  - Remove a misguided, NMI-unsafe KASAN callback
    from the NMI-safe irq_work path used by perf.
 
  - Fix uncore events on Ice Lake servers.
 
  - Someone booted maxcpus=1 on an SNB-EP, and the
    uncore driver emitted warnings and was probably
    buggy. Fix it.
 
  - KCSAN found a genuine data race in the core perf
    code. Somewhat ironically the bug was introduced
    through a recent race fix. :-/ In our defense, the
    new race window was much more narrow. Fix it.
