Comment(by werner):

 Here's a patch for measuring the time during which interrupts are
 globally disabled:

 Another source of interrupt latency can be the time during which a
 specific interrupt is disabled. The execution time of an interrupt
 also (indirectly) shows up in this, but it's better to measure it
