I did that because the build will fail at this stage without the Ovmf
changes:
build.py...
/root/kernels/ovmf-build-X64/OvmfPkg/OvmfPkgX64.dsc(...): error 4000: Instance of library class [VmgExitLib] is not found
in [/root/kernels/ovmf-build-X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/PeiCpuExceptionHandlerLib.inf] [X64]
consumed by module [/root/kernels/ovmf-build-X64/UefiCpuPkg/CpuMpPei/CpuMpPei.inf]
- Failed -
Is there a way that we can avoid updating the Ovmf DSC files entirely when
a DSC file specifies one of the exception libraries? Otherwise, I guess I
would have to update the Ovmf DSC files before this patch? Or I could make
the changes to use the VmgExitLib all at once, which would be a single
patch that adds the VmgExitLib and corresponding AMD exception handling
source files at once across UefiCpuPkg and Ovmf?
(Which triggers that I need to check other DSC files that include these
exception libraries to be sure I don't break anything).

Yup, makes sense, will do.
