Subject: [RFC PATCH v7 07/37] KVM: lapic: Rename lapic get/set_reg() helpers
Date: Tue, 10 Jun 2025 23:23:54 +0530 [thread overview]
Message-ID: <20250610175424.209796-8-Neeraj.Upadhyay@amd.com> (raw)
In-Reply-To: <20250610175424.209796-1-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 to signify that they are part of apic api.
While at it, fix line wrap in kvm_apic_get_state().
No functional change intended.
