Subject: [Qemu-devel] [PATCH 5/5] s390x/kvm: execute the first cpu reset on the vcpu thread
Date: Thu, 28 Aug 2014 13:58:52 +0200	[thread overview]
Message-ID: <1409227132-55354-6-git-send-email-jfrei@linux.vnet.ibm.com> (raw)
In-Reply-To: <1409227132-55354-1-git-send-email-jfrei@linux.vnet.ibm.com>

From: David Hildenbrand <dahi@linux.vnet.ibm.com>

As all full cpu resets currently call into the kernel to do initial cpu reset,
let's run this reset (triggered by cpu_s390x_init()) on the proper vcpu thread.
