[RFC, PATCH 7/24] i386 Vmi memory hole

[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.
