From d11dfed5d700b8973d5742300e04b2aaa9d11217 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Wed, 18 Dec 2019 13:55:24 -0800 Subject: KVM: MIPS: Move all vcpu init code into kvm_arch_vcpu_create() Fold init() into create() now that the two are called back-to-back by common KVM code (kvm_vcpu_init() calls kvm_arch_vcpu_init() as its last action, and kvm_vm_ioctl_create_vcpu() calls kvm_arch_vcpu_create() immediately thereafter). Rinse and repeat for kvm_arch_vcpu_uninit() and kvm_arch_vcpu_destroy(). This paves the way for removing kvm_arch_vcpu_{un}init() entirely. No functional change intended.
