From 57f889471c0fb55cbb0db98b30483040e2065bd9 Mon Sep 17 00:00:00 2001 From: John Ogness Date: Wed, 11 Nov 2015 14:48:50 +0100 Subject: [PATCH] powerpc/powermac: set IRQF_NO_THREAD for xmon/cascade handlers 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.
