[Xen-ia64-devel] [patch 03/16] Initialise xen_start_info earlier in setup_arch()

[Simon Horman <horms@xxxxxxxxxxxx>]

xen_start_info needs to be set before efi_init() is called on ia64
because xen_machine_kexec_setup_resources() is indirectly
called by efi_init() and it needs a working is_initial_xendomain();
