VmgExitLib once was designed to provide interfaces to support #VC handler and issue VMGEXIT instruction. After TDVF (enable TDX feature in OVMF) is introduced, this library is updated to support #VE as well. Now the name of VmgExitLib cannot reflect what the lib does. This patch-set creates CcExitLib which is a simple copy of VmgExitLib except some of the API names are renamed with a CcExitLib prefix. For example VmgExit is renamed as CcExitLibVmgExit. To make sure the build will not be broken by the renaming, this patch-set first creates CcExitLib (Patch #1/2). Then VmgExitLib is replaced by CcExitLib in UefiCpuPkg/UefiPayloadPkg/OvmfPkg (Patch #3/4/5/6). After that VmgExitLib is deleted (Patch #7/8). At last Maintainers.txt is updated (Patch #9). Code: https://github.com/mxu9/edk2/tree/CcExitLib.v2 v2 changes: - Patch #3 is added to import CcExitLib in OvmfPkg's *.dsc. This is to prevent the building from being broken in the following patches.
