Subject: [PATCH v2 06/15] mshv_vtl: Make sint vector architecture neutral

From: Naman Jain <[email-masked]>
Date: Thu, 23 Apr 2026 12:41:56 +0000

Generalize Synthetic interrupt source vector (sint) to use
vmbus_interrupt variable instead, which automatically takes care of
architectures where HYPERVISOR_CALLBACK_VECTOR is not present (arm64).
