Subject: [PATCH 08/57] ia64: irq: Remove IRQF_DISABLED
Date: Wed, 21 Sep 2011 17:28:09 +0800	[thread overview]
Message-ID: <1316597339-29861-9-git-send-email-yong.zhang0@gmail.com> (raw)
In-Reply-To: <1316597339-29861-1-git-send-email-yong.zhang0@gmail.com>

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.
