30           Select this if you want to use prioritized IRQ handling.
31           This feature prevents higher priority ISR to be interrupted
32           by lower priority IRQ even IRQF_DISABLED flag is not set.
33           This may be useful in embedded applications, where are strong
34           requirements for timing.
35           Say N here, unless you have a specialized requirement.
