[PATCH 13/57] mn10300: irq: Remove IRQF_DISABLED

From: Yong Zhang
Date: Wed Sep 21 2011 - 05:31:19 EST


Since commit [c58543c8: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.
