Subject: [PATCH 01 of 24] xen: add missing __HYPERVISOR_arch_[0-7] definisions
	which ia64 needs

From: Isaku Yamahata <yamahata@...inux.co.jp>

Add xen hypercall numbers defined for arch specific use.
ia64/xen domU uses __HYPERVISOR_arch_1 to manipulate paravirtualized
IOSAPIC. Although all those constants aren't used yet by IA64 at this
moment, add all arch specific hypercall numbers.
