Move cet.inc to UefiCpuPkg\PiSmmCpuDxeSmm, beacuse CET feature is only used in SMM. Patch V6: Cet.inc only contains definitions for x86 CPU. Move the file to \Ia32 and \X64 folder. Refine code for cet.inc. Patch V5: File cet.inc will be used in both MdePkg UefiCpuPkg. Move cet.inc file from UefiCpuPkg to MdePkg. Use macro CR4_CET_BIT to replace hard code value for both LongJump.nasm and SetJump.nasm. Patch V4: Separate the changes to 5 patches. 1) Add macro definitions for CET feature for NASM files. 2) Use macro CR4_CET_BIT to replace hard code value in Cet.nasm. 3) Use CET macro definitions in Cet.inc for SmiEntry.nasm files. 4) Only change CR4.CET bit for enable/disable CET. 5) Backup and Restore MSR IA32_U_CET in SMI handler. Remove some unused code. It is no need to clear MSR IA32_S_CET, because clear CR4.CET bit will disable all CET functions. Since CET is disabled between clear CR4.CET and run 'rsm', it is no need to delay MSR IA32_S_CET restoration. Patch V3: Remove the 3rd patch. mSmmInterruptSspTables is a global variable. It is unnecessary to initializ it to zero manually. Patch V2: No function change with Patch V1. Split the patch to into 3 separate patches. Sheng Wei (5): UefiCpuPkg: Add macro definitions for CET feature for NASM files. UefiCpuPkg: Use macro CR4_CET_BIT to replace hard code value in Cet.nasm. UefiCpuPkg: Use CET macro definitions in Cet.inc for SmiEntry.nasm files. UefiCpuPkg: Only change CR4.CET bit for enable and disable CET. UefiCpuPkg: Backup and Restore MSR IA32_U_CET in SMI handler.
