[Xen patchbot-unstable <patchbot-unstable@xxxxxxxxxxxxxxxxxxx>]

# HG changeset patch
# User Isaku Yamahata <yamahata@xxxxxxxxxxxxx>
# Date 1224124385 -32400
# Node ID 5450b008afcec7a5184a0124aab3be639933aec8

[IA64] rename struct viosapic_rte in order to share VTD code.

VTD code uses vioapic_redir_entry structure,
This patch lets viosapci.h use the same structure name and some fields.
That IA64 can use the same VTD code with ia32
