From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sean Christopherson Date: Tue, 22 Oct 2019 01:59:19 +0000 Subject: [PATCH 39/45] KVM: MIPS: Move all vcpu init code into kvm_arch_vcpu_create() Message-Id: <20191022015925.31916-40-sean.j.christopherson@intel.com> List-Id: References: <20191022015925.31916-1-sean.j.christopherson@intel.com> In-Reply-To: <20191022015925.31916-1-sean.j.christopherson@intel.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Marc Zyngier , James Hogan , Paul Mackerras , Christian Borntraeger , Janosch Frank , Paolo Bonzini , =?UTF-8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= Cc: James Morse , Julien Thierry , Suzuki K Poulose , David Hildenbrand , Cornelia Huck , Sean Christopherson , Vitaly Kuznetsov , Wanpeng Li , Jim Mattson , Joerg Roedel , linux-arm-kernel@lists.infradead.org, kvmarm@lists.cs.columbia.edu, linux-mips@vger.kernel.org, kvm-ppc@vger.kernel.org, kvm@vger.kernel.org, linux-kernel@vger.kernel.org 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.
