Roger Pau Monné 0df8b29da3 xen: introduce a newbus function to allocate unused memory ... In order to map memory from other domains when running on Xen FreeBSD uses unused physical memory regions. Until now this memory has been allocated using bus_alloc_resource, but this is not completely safe as we can end up using unreclaimed MMIO or ACPI regions. Fix this by introducing a new newbus method that can be used by Xen drivers to request for unused memory regions. On amd64 we make sure this memory comes from regions above 4GB in order to prevent clashes with MMIO/ACPI regions. On i386 there's nothing we can do, so just fall back to the previous mechanism.
