Subject: [PATCH v18 032/121] KVM: x86/mmu: introduce config for PRIVATE KVM MMU
Date: Mon, 22 Jan 2024 15:53:08 -0800
Message-Id: <591420ca62f0a9ac2478c2715181201c23f8acf0.1705965635.git.isaku.yamahata@intel.com>

From: Isaku Yamahata <isaku.yamahata@intel.com>

To keep the case of non TDX intact, introduce a new config option for
private KVM MMU support.  At the moment, this is synonym for
CONFIG_INTEL_TDX_HOST && CONFIG_KVM_INTEL.  The config makes it clear
that the config is only for x86 KVM MMU.
