No, you miss nothing. Parth Dixit is still working on XEN ACPI for ARM64, before it's in full function, how about introduce a Kconfig CONFIG_XEN_ACPI and let it depends on x86? when XEN ACPI for ARM64 comes, we can enable ARM64 for CONFIG_XEN_ACPI and fix the problems above. Stefano, Parth, what do you think?
