From 3781528e3045e7c9cc7c4846e0f675b1f353655f Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Fri, 25 Sep 2015 23:41:14 +0200 Subject: KVM: arm/arm64: rename pause into power_off The kvm_vcpu_arch pause field is renamed into power_off to prepare for the introduction of a new pause field. Also vcpu_pause is renamed into vcpu_sleep since we will sleep until both power_off and pause are false.
