This patchset is for more paravirtualization on ia64/pv_ops. - paravirtualize fsys call (fsys.S) by multi compile - paravirtualize gate page (gate.S) by multi compile - support save/restore For this purpose, the followings needs to be paravirtualized - ar.itc instruction - sched_clock() This is because timer may changed before/after saving/restoring.
