Subject: [Qemu-devel] [PATCH 28/29] cpus: Fix pausing TCG CPUs while in vCPU thread
Date: Thu,  2 May 2013 15:35:54 +0200	[thread overview]
Message-ID: <1367501755-32272-29-git-send-email-afaerber@suse.de> (raw)
In-Reply-To: <1367501755-32272-1-git-send-email-afaerber@suse.de>

Due to a preceding while loop, no CPU would've been put into stopped
state. Reinitialize the variable.
This fixes commit d798e97456658ea7605303b7c69b04ec7df95c10 (Allow to use
pause_all_vcpus from VCPU context) for non-KVM case.

While at it, change a 0 to false, amending commit
4fdeee7cd4c8f90ef765537b9346a195d9483ab5 (cpu: Move stop field to
CPUState).
