[RFC, PATCH 7/24] i386 Vmi memory hole
Create a configurable hole in the linear address space at the top
of memory. A more advanced interface is needed to negotiate how
much space the hypervisor is allowed to steal, but in the end, it
seems most likely that a fixed constant size will be chosen for
the compiled kernel, potentially propagated to an information
page used by paravirtual initialization to determine interface
compatibility.
