One of maintainers of IB driver suggested a theory. What is the way that Xen
allocates memory? Are there guarantees about allocation of physical contiguous
memory? E.g., if I request alloc_pages(GPF_KERNEL, 6) - (256kB), are these 
pages physically contiguous? Or are these pages guest contiguous only?
