Usually ASSRET() is "(void)0". Therefore if VPD allocation
fails with xenheap shortage or fragmentation, NULL pointer
access occurs in vmx_final_setup_guest().
This patch fixes it.

This is necessary for kexec/kdump for xen/ia64. kexec-tools needs to know
real machine's memory map.

The Intel GFW still calls this, so we might as well implemented it.
Based on patch from Anthony and Wing, adds additional cleanups and
toning down of some of the error messages.

Fix wrong python list assignment for "monitor=1". The old assignment
only works when using qemu-dm.debug in configure file.

This enables the switch to the generic flavor ia64 kernel for the -xen
and -xen0 kernels. -xenU is changed to a CONFIG_IA64_XEN build.

This allows us to easily switch between hardware or software iommu and
simple remapping. The Xen machine vector is only intended for domU
guests at this point.

This paravirtualizes the iommu driver for HP Integrity systems. This
allows dom0 to use the iommu just as it would on native hardware.

Paravirtualize our copy of swiotlb. A lot of the s/virt_to_phys/virt_to_bus
converstions have already been done in upstream, so I won't special case
them here.

We get a bad pointer dereference if we don't fill something in
here. -1 will give us a global allocation, which is good enough
until we have better NUMA support.

These will be paravirtualized in upcoming commits. We're copying
lib/swiotlb.c into arch/ia64/xen/swiotlb.c simply for convenience.
Changes should be merged back into lib/swiotlb.c once Xen support
merges into Linux.

Currently it returns supported_bootloaders as a string. This patch
returns supported_bootloaders as a 'string set' - per the spec. The
c-bindings fail to parse response, expecting a set but only finding a
string.
