Subject: [PATCH 7.2.y 1/7] KVM: x86: Move tdp_enabled from kvm_host.h to mmu.h
Date: Fri, 11 Sep 2026 06:41:30 -0400	[thread overview]
Message-ID: <20260911104136.194961-1-sashal@kernel.org> (raw)
In-Reply-To: <2026090906-angling-trickily-a20c@gregkh>

From: Sean Christopherson <seanjc@google.com>

[ Upstream commit af0dbcaaa2bbc90ba8e6f696be725c4522face08 ]

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.
