Defines CONFIG_ARGO when enabled. Default: disabled. When the Kconfig option is enabled, the Argo hypercall implementation will be included, allowing use of the hypervisor-mediated interdomain communication mechanism. Argo is implemented for x86 and ARM hardware platforms. Availability of the option depends on EXPERT and Argo is currently an experimental feature.
