Subject: [PATCH v3 02/16] KVM: VMX: Move architectural "vmcs" and "vmcs_hdr" structures to public vmx.h
Date: Fri, 13 Feb 2026 17:26:48 -0800 [thread overview]
Message-ID: <20260214012702.2368778-3-seanjc@google.com> (raw)
In-Reply-To: <20260214012702.2368778-1-seanjc@google.com>
Move "struct vmcs" and "struct vmcs_hdr" to asm/vmx.h in anticipation of
moving VMXON/VMXOFF to the core kernel (VMXON requires a "root" VMCS with
the appropriate revision ID in its header).
No functional change intended.
