662 This option enables a workaround that fixes a source of
663 spurious interrupts. This is recommended when threaded
664 interrupt handling is used on systems where the generation of
665 superfluous "boot interrupts" cannot be disabled.
666
667 Some chipsets generate a legacy INTx "boot IRQ" when the IRQ
668 entry in the chipset's IO-APIC is masked (as, e.g. the RT
669 kernel does during interrupt handling). On chipsets where this
670 boot IRQ generation cannot be disabled, this workaround keeps
671 the original IRQ line masked so that only the equivalent "boot
672 IRQ" is delivered to the CPUs. The workaround also tells the
673 kernel to set up the IRQ handler on the boot IRQ line. In this
674 way only one interrupt is delivered to the kernel. Otherwise
675 the spurious second interrupt may cause the kernel to bring
676 down (vital) interrupt lines.
677
678 Only affects "broken" chipsets. Interrupt sharing may be
679 increased on these systems.
