Thank you to enable this feature. I have 2 comments, after a very quick review.
1) I notice it is enabled by default "gEfiMdeModulePkgTokenSpaceGuid.PcdNullPointerDetection|TRUE". Would you please provide the information on how many open source platforms are validated? Such as, IA platform (VLV2, Quark), emu platform (OVMF, NT32)? Or do we need validate any ARM platform? 2) I am thinking about CSM platform. Do you think we can make it dynamic, as such, a platform may set the validate based upon CSM enable/disable? Or if we need update the CSM module to patch the page table automatically? Once this is feature is ON.
