xen/ia64 with dom0 vp model doesn't need the work around of blkback anymore.
ifndef them out.
xen/ia64 dom0 vp model is a big change so that xen/ia64 with the old model
(P=M) still remains as the compile option.
Hopefully the work around will be eliminated in the future completely.

Could you create a patch which adds an additional config option
CONFIG_XEN_IA64_DOM0_NON_VP which would be equivalent to
defined(CONFIG_IA64) && !defined(CONFIG_XEN_IA64_DOM0_VP).

This would then simplify the ifdef's in blkback and also the swiotlb
Makefile change.
