[RFC PATCH v7 15/37] KVM: x86: apic_test_vector() to common code

From: Neeraj Upadhyay
Date: Tue Jun 10 2025 - 14:01:06 EST


Move apic_test_vector() to apic.h in order to reuse it in the
Secure AVIC guest apic driver in later patches to test vector
state in the APIC backing page.

No function change intended.

Changes since v6:

- Moved macro and function renames outside of this patch.
