* ia64/pv_ops: implement binary patching optimization for native.Isaku Yamahata2009-03-261-19/+24
| | | | | | | | | implement binary patching optimization for pv_cpu_ops. With this optimization, indirect call for pv_cpu_ops methods can be converted into inline execution or direct call. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Tony Luck <tony.luck@intel.com>

* [IA64] pvops: paravirtualize entry.SIsaku Yamahata2008-05-281-0/+60
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.
