I was thinking the same thing.

However this patch series doesn't add much code outside
drivers/xen/efi.c and include/xen/interface/platform.h.
I think it wouldn't be fair to ask Daniel to refactor the efi code
currently under arch/x86 to an arch-independent location.
Whoever comes in later and adds EFI Xen support for ARM can do that.
