Isaku Yamahata	4df8d22bbb	[IA64] pvops: paravirtualize entry.S ... paravirtualize ia64_swtich_to, ia64_leave_syscall and ia64_leave_kernel. They include sensitive or performance critical privileged instructions so that they need paravirtualization. To paravirtualize them by single source and multi compile they are converted into indirect jump. And define each pv instances.
