Subject: [PATCH 1/9] KVM: x86: Co-locate initialization of feature MSRs in kvm_arch_vcpu_create()
Date: Fri, 2 Aug 2024 11:55:03 -0700 [thread overview]
Message-ID: <20240802185511.305849-2-seanjc@google.com> (raw)
In-Reply-To: <20240802185511.305849-1-seanjc@google.com>
Bunch all of the feature MSR initialization in kvm_arch_vcpu_create() so
that it can be easily quirked in a future patch.
No functional change intended.
