Subject: [PATCH 18/22] KVM: x86/mmu: cleanup functions that initialize shadow MMU
Date: Mon, 11 May 2026 11:06:44 -0400	[thread overview]
Message-ID: <20260511150648.685374-19-pbonzini@redhat.com> (raw)
In-Reply-To: <20260511150648.685374-1-pbonzini@redhat.com>

Now that the GVA->GPA page walker is initialized independently,
init_kvm_softmmu() does not do anything more than calling
kvm_init_shadow_mmu() so eliminate it from the call chain.
At the same time, rename kvm_init_shadow_mmu() to
init_kvm_shadow_mmu() for consistency with init_kvm_tdp_mmu().
