How this was tested?
I can't even build this (without -D SMM_REQUIRE=TRUE).

/home/kraxel/projects/edk2/OvmfPkg/OvmfPkgX64.dsc(...): error 4000: Instance of library class [SmmRelocationLib] is not found
	in [/home/kraxel/projects/edk2/OvmfPkg/PlatformPei/PlatformPei.inf] [X64]
	consumed by module [/home/kraxel/projects/edk2/OvmfPkg/PlatformPei/PlatformPei.inf]

I doubt it passes CI.

take care,
  Gerd
