Anyone tracing interrupt enable/disable?

I'm pretty new to LTT, so please forgive what may be an ignorant
question, but is anyone tracing interrupt enable/disable events, such as
local_irq_enable, local_irq_restore, etc.? This would seem to be very
useful in certain circumstances, but might be tricky/performance
critical enough to require a specialized function or set of functions.
