> The IRQF_DISABLED is a NOOP and has been scheduled for removal since
> Linux v2.6.36 by commit 6932bf37bed4 ("genirq: Remove IRQF_DISABLED from
> core code").
>
> According to commit e58aa3d2d0cc ("genirq: Run irq handlers with
> interrupts disabled") running IRQ handlers with interrupts enabled can
> cause stack overflows when the interrupt line of the issuing device is
> still active.
>
> This patch ends the grace period for IRQF_DISABLED (i.e., SA_INTERRUPT
> in older versions of Linux) and removes the definition and all remaining
> usages of this flag.
