[Xen-ia64-devel] [PATCH 00/13] ia64/pv_ops, xen: more paravirtualization.

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

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.

For convenience the working full source is available from

branch: ia64-pv-ops-2008oct20-xen-ia64-optimized-domu
