From 1f5538a8e2fd3602cd507897c16ee647360a0423 Mon Sep 17 00:00:00 2001 From: Roman Kisel Date: Mon, 28 Apr 2025 14:07:36 -0700 Subject: [PATCH] arm64: hyperv: Initialize the Virtual Trust Level field Various parts of the hyperv code need to know what VTL the kernel runs at, most notably VMBus needs that to establish communication with the host. Initialize the Virtual Trust Level field to enable booting in the Virtual Trust Level.
