Thread-topic: [Xen-ia64-devel][PATCH] optimize entry and exit path
VMM save/restore r4~r7 and unat to handle virtualization fault and mmio access,
but it is not necessary for other faults to save/restore these registers.
This patch is to save/restore these registers only when dtlb and virtualization 
fault happen.

Signed-off-by: Anthony Xu < anthony.xu@xxxxxxxxx>

Thanks,
Anthony
