|

* IRQ flags tracing: follow the state of the hardirq and softirq flags and
|

* provide callbacks for transitions between ON and OFF states.
|

*
|

* This file gets included from lowlevel asm headers too, to provide
|
||||
* wrapped versions of the local_irq_*() APIs, based on the

* raw_local_irq_*() macros from the lowlevel headers.
