Date: Mon, 14 Feb 2022 08:16:10 -0500 From: Paolo Bonzini <pbonzini@...hat.com> To: linux-kernel@...r.kernel.org, kvm@...r.kernel.org Cc: seanjc@...gle.com Subject: [PATCH v2 1/5] KVM: x86: use static_call_cond for optional callbacks SVM implements neither update_emulated_instruction nor set_apic_access_page_addr. Remove an "if" by calling them with static_call_cond().
