+ If PMM IRQ is the only IRQ at EXCM level it is safe to
+ treat it as NMI, which improves accuracy of profiling.
+
+ If there are other interrupts at or above PMM IRQ priority level
+ but not above the EXCM level, PMM IRQ still may be treated as NMI,
+ but only if these IRQs are not used. There will be a build warning
