Good point. I tried compiling it against the x86 architecture and it fails because it can't find the definition for arm_smccc_smc(). But it would compile for the ARM64 architecture with both ACPI and MELLANOX _PLATFORM not set, so I'll change it to ARM64 && ((MELLANOX_PLATFORM && ACPI) || COMPILE_TEST) instead.
The dependency on ACPI is because our BlueField SoC firmware only uses ACPI to pass the device mappings, and MELLANOX_PLATFORM because this device is only seen on the Mellanox BlueField SoC so it would be pointless to be used elsewhere, but these doesn't prevent it from being compiled.
