Subject: [PATCH 4/7] KVM: x86: Inline kvm_get_apic_mode() in lapic.h
Date: Wed,  9 Oct 2024 11:17:38 -0700	[thread overview]
Message-ID: <20241009181742.1128779-5-seanjc@google.com> (raw)
In-Reply-To: <20241009181742.1128779-1-seanjc@google.com>

Inline kvm_get_apic_mode() in lapic.h to avoid a CALL+RET as well as an
export.  The underlying kvm_apic_mode() helper is public information, i.e.
there is no state/information that needs to be hidden from vendor modules.

No functional change intended.
