Hi Feng Wu,
In my patchset, I created a new member ir_table->base_old_phys; In the
normal kernel, everything is the same. In kdump kernel, ir_table->base
is used for a buffer, and ir_table->base_old_phys is the physical
address of the tables used by the old kernel, also being used by the

With VT-d Posted-Interrupts enabled, external interrupts from
direct-assigned devices can be delivered to guests without VMM
intervention when guest is running in non-root mode.
