Subject: [PATCH 05/14] KVM: VMX: Move CPU_BASED_CR8_{LOAD,STORE}_EXITING filtering out of setup_vmcs_config()
Date: Mon, 27 Jun 2022 18:04:31 +0200 [thread overview]
Message-ID: <20220627160440.31857-6-vkuznets@redhat.com> (raw)
In-Reply-To: <20220627160440.31857-1-vkuznets@redhat.com>
As a preparation to reusing the result of setup_vmcs_config() in
nested VMX MSR setup, move CPU_BASED_CR8_{LOAD,STORE}_EXITING filtering
to vmx_exec_control().
No functional change intended.
