Subject: [RFC PATCH v8 07/35] KVM: x86: Rename lapic get/set_reg() helpers
Date: Wed, 9 Jul 2025 09:02:14 +0530	[thread overview]
Message-ID: <20250709033242.267892-8-Neeraj.Upadhyay@amd.com> (raw)
In-Reply-To: <20250709033242.267892-1-Neeraj.Upadhyay@amd.com>

In preparation for moving kvm-internal __kvm_lapic_set_reg(),
__kvm_lapic_get_reg() to apic.h for use in Secure AVIC APIC driver,
rename them as part of the APIC API.

No functional change intended.
