    irq: Consolidate do_softirq() arch overriden implementations · 7d65f4a6
    Frederic Weisbecker authored
    All arch overriden implementations of do_softirq() share the following
    common code: disable irqs (to avoid races with the pending check),
    check if there are softirqs pending, then execute __do_softirq() on
    a specific stack.
    
    Consolidate the common parts such that archs only worry about the
    stack switch.
