ia64/pv_ops: add hooks to paravirtualize fsyscall implementation.
Add two hooks, paravirt_get_fsyscall_table() and paravirt_get_fsys_bubble_doen() to paravirtualize fsyscall implementation. This patch just add the hooks fsyscall and don't paravirtualize it. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Tony Luck <tony.luck@intel.com>
