From c8235c2891d0561960fd5d62fdda58cfb6e503b2 Mon Sep 17 00:00:00 2001 From: Simon Guo Date: Wed, 23 May 2018 15:02:10 +0800 Subject: [PATCH] KVM: PPC: Remove load/put vcpu for KVM_GET/SET_ONE_REG ioctl Since the vcpu mutex locking/unlock has been moved out of vcpu_load() /vcpu_put(), KVM_GET_ONE_REG and KVM_SET_ONE_REG doesn't need to do ioctl with loading vcpu anymore. This patch removes vcpu_load()/vcpu_put() from KVM_GET_ONE_REG and KVM_SET_ONE_REG ioctl.
