 When late loading the patches for Genoa or Bergamo, there may be one spurious
 NMI observed per physical core. These NMIs are benign and don't cause any
 functional issue but will result in kernel messages being logged.

+NOTE: When running 5.19+ kernels on Genoa or Bergamo systems, some microcode
+patches are known to trigger warnings in the PMI handler. The following are
+the required minimum patch levels to address this problem:
