    genirq: Move initial affinity setup to irq_startup() · 2e051552
    Thomas Gleixner authored
    The startup vs. setaffinity ordering of interrupts depends on the
    IRQF_NOAUTOEN flag. Chained interrupts are not getting any affinity
    assignment at all.
    
    A regular interrupt is started up and then the affinity is set. A
    IRQF_NOAUTOEN marked interrupt is not started up, but the affinity is set
    nevertheless.
    
    Move the affinity setup to startup_irq() so the ordering is always the same
    and chained interrupts get the proper default affinity assigned as well.
