- Basic hypervisor.h and interface.h definitions. - Skeleton enlighten.c, set xen_start_info to an empty struct. - Make xen_initial_domain dependent on the SIF_PRIVILIGED_BIT. The new code only compiles when CONFIG_XEN is set, that is going to be added to arch/arm/Kconfig in patch #11 "xen/arm: introduce CONFIG_XEN on ARM". Changes in v3: - improve comments.
