    Out-of-band IRQs and EVL thread contexts would usually compete for
    such lock, which would require hard irqs to be disabled while holding
    it. Therefore we would not generally benefit from the preemption
    disabling feature we are going to add to the EVL-specific
    spinlock. Make it a hard lock to clarify the intent.
