This patch set is intended for the next merge window. They are just
enhancements of the already merged patches or ia64 porting from x86
paravirt techniques and that their quality is enough for merge.

This patch set is for more paravirtualization on ia64/xen domU.
This patch set does
- remove existing warnings
- 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.

For convenience the working full source is available from
http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/
branch: ia64-pv-ops-2008dec12-xen-ia64-optimized-domu
