From a602f0f2f04f150fa1f7312b9e601e8e1a5afe10 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 17 Dec 2009 12:43:29 +0100 Subject: arm/{pxa,sa1100,nomadik}: Don't disable irqs in set_next_event and set_mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These functions are called with irqs already off. This commit removes the calls to raw_local_irq_save and raw_local_irq_restore on platforms that don't have to use a shared interrupt for their timekeeping.
