Subject: [PATCH] powerpc: set IRQF_NO_THREAD for xmon/cascade handlers

From: John Ogness <[email-masked]>
Date: Wed, 11 Nov 2015 14:48:50 +0100

The xmon and cascade irq handlers must not run as threads.
pmac_pic_lock is already a raw_spinlock, but the irq flag
IRQF_NO_THREAD needs to be set as well.
