From: David Hildenbrand Date: Tue, 6 May 2014 14:33:42 +0000 (+0200) Subject: KVM: s390: a VCPU is already started when delivering interrupts X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3192c639505502753bb7ded1b466a84546286330;p=openwrt%2Fstaging%2Fblogic.git KVM: s390: a VCPU is already started when delivering interrupts This patch removes the start of a VCPU when delivering a RESTART interrupt. Interrupt delivery is called from kvm_arch_vcpu_ioctl_run. So the VCPU is already considered started - no need to call kvm_s390_vcpu_start. This function will early exit anyway.
