Between the following two patches:
[edk2-devel] [PATCH v4 07/40]
UefiCpuPkg: Implement library support for VMGEXIT
[edk2-devel] [PATCH v4 08/40]
UefiCpuPkg/CpuExceptionHandler: Add base support for the #VC exception
please locate all the platform DSC files that rely on any of the
exception handler library instances that you extend with a VmgExitLib
dependency in v4 08/40. And then please insert patches (one patch per
Pkg) for resolving VmgExitLib in those DSC files.
