This set of patches is the minimal subset required to get the kexec path working again on Xen 4.x

kdump kernels can't boot if x2apic mode is enabled and the ACPI tables dont state this fact.  They also cant boot at all with interrupt remapping enabled.

These patches cause xen to track the local apic boot state and return to it before kexec'ing to a new kernel.  It also makes sure to disable IO virtualisation.
