Subject: [PATCH 25/45] KVM: s390: Move guts of kvm_arch_vcpu_init() into kvm_arch_vcpu_create()
Date: Mon, 21 Oct 2019 18:59:05 -0700	[thread overview]
Message-ID: <20191022015925.31916-26-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20191022015925.31916-1-sean.j.christopherson@intel.com>

Move all of kvm_arch_vcpu_init(), which is invoked at the very end of
kvm_vcpu_init(), into kvm_arch_vcpu_create() in preparation of moving
the call to kvm_vcpu_init().  Moving kvm_vcpu_init() is itself a
preparatory step for moving allocation and initialization to common KVM
code.

No functional change inteded.
