Subject: [patch 08/15] powerpc: Convert beatic_irq_mask_lock to raw_spinlock
Date: Thu, 18 Feb 2010 12:22:52 -0000 [thread overview]
Message-ID: <20100218122000.431550876@linutronix.de> (raw)
In-Reply-To: 20100218121904.620984825@linutronix.de
beatic_irq_mask_lock needs to be a real spinlock in RT. Convert it to
raw_spinlock.
