Subject: [PATCH 15/28] KVM: x86: Move definition of X2APIC_MSR() to lapic.h
Date: Thu, 29 May 2025 16:40:00 -0700 [thread overview]
Message-ID: <20250529234013.3826933-16-seanjc@google.com> (raw)
In-Reply-To: <20250529234013.3826933-1-seanjc@google.com>
Dedup the definition of X2APIC_MSR and put it in the local APIC code
where it belongs.
No functional change intended.
