From d7e25f3394ba05a6d64cb2be42c2765fe72ea6b2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar <mingo@elte.hu> Date: Fri, 16 Feb 2007 01:28:24 -0800 Subject: [PATCH] [PATCH] genirq: remove IRQ_DISABLED Now that disable_irq() defaults to delayed-disable semantics, the IRQ_DISABLED flag is not needed anymore.
