Subject: [patch 2/3] x86: io-apic - declare irq_cfg_lock for SPARSE_IRQ only
Date: Thu, 04 Sep 2008 22:37:50 +0400	[thread overview]
Message-ID: <48c02b69.0407560a.0a50.7f99@mx.google.com> (raw)
In-Reply-To: 20080904183748.950151853@gmail.com

[-- Attachment #1: x86-apic-irq_cfg_lock --]
[-- Type: text/plain, Size: 825 bytes --]

We use irq_cfg_lock lock in SPARSE_IRQ only context so
move it under #ifdef and compiler will be happy.
