Hi Daniel, I must say, I am not too thrilled with the approach you have chosen here. #including .c files in other .c files, and using #defines to override C functions or other stub functionality is rather fragile. In particular, it means we have to start caring about not breaking Xen/x86 code when making modifications to the EFI stub, and that code is already difficult enough to maintain, given that it is shared between ARM, arm64 and x86, and runs either from the decompressor or the kernel proper (arm64) but in the context of the UEFI firmware. None of the stub code currently runs in ordinary kernel context. So please, could you try to find another way to do this?
