From 10b496832efa046ab9222a8cf132681730886db3 Mon Sep 17 00:00:00 2001 From: Varun Swara Date: Wed, 9 Dec 2009 10:02:19 +0000 Subject: [PATCH] ARM: Do not allow the probing of the local timer Since this IRQ descriptor doesn't have an action registered, it is allowed for probing via probe_irq_on/off() and it will be disabled by the latter function. This patch sets the IRQ_NOPROBE status bit for the local timer descriptor.
