Pull perf fixes from Ingo Molnar:
"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"
