The VT-d and AMD IOMMU implementations both use the general x86 IOMMU page

By wrapping the few EFI handler functions used by the Xen boot process

Hello,
I am unable to mcompile xen-tools from source.
here is the "stacktrace":
ln -f xenstore xenstore-watch
gcc xenstore_control.o

Tests which did not succeed, but are not blocking:

Coverity points out that the "d &&" is redundant.
