Subject: [PATCH v2] kvm:vmx: Fix typos comment in __loaded_vmcs_clear()
Date:   Tue, 22 Feb 2022 18:40:29 +0800

From: Peng Hao <flyingpeng@tencent.com>

Fix a comment documenting the memory barrier related to clearing a
loaded_vmcs; loaded_vmcs tracks the host CPU the VMCS is loaded on via
the field 'cpu', it doesn't have a 'vcpu' field.
