Subject: [Patch V2 7/8] MdeModulePkg/DxeIpl: Remove duplicated code to enable NX
Date: Fri, 31 Mar 2023 17:33:43 +0800 [thread overview]
Message-ID: <20230331093344.2609-8-dun.tan@intel.com> (raw)
In-Reply-To: <20230331093344.2609-1-dun.tan@intel.com>
In IA32 code, remove the duplicated code to enable NX.
In the previous patch, IA32 code also uses the new
CreateIdentityMappingPageTables() to create PAE page table.
This function calls EnableExecuteDisableBit if needed.
