Subject[PATCH] omap_l3_noc.c: remove IRQF_DISABLED flag
Date
The IRQF_DISABLED flag is a NOOP and scheduled to be removed.  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.
