[Xen-ia64-devel] [PATCH 04/15] ia64/pv_ops/xen: preliminary to paravirtualizing fsys.S for xen.

2009-03-04 Thread Isaku Yamahata 
This is a preliminary patch to paravirtualizing fsys.S.
compile fsys.S twice one for native and one for xen, and switch
them at run tine.
Later fsys.S will be paravirtualized.
