/*
* kmem_alloc_nofault:
*
* Same as kmem_alloc_pageable, except that it create a nofault entry.
* Allocate a virtual address range with no underlying object and
* no initial mapping to physical memory. Any mapping from this
* range to physical memory must be explicitly created prior to
* its use, typically with pmap_qenter(). Any attempt to create
* a mapping on demand through vm_fault() will result in a panic.
