Subject: [PATCH v4 08/30] KVM: x86: Move tdp_enabled from kvm_host.h to mmu.h
Date: Fri, 12 Jun 2026 17:03:07 -0700	[thread overview]
Message-ID: <20260613000329.732085-9-seanjc@google.com> (raw)
In-Reply-To: <20260613000329.732085-1-seanjc@google.com>

Relocated the declaration of tdp_enabled into mmu.h, and opportunistically
hoist tdp_mmu_enabled up to the top so that the two are co-located.

No functional change intended.
