  Make preparations for increasing the size of the kernel virtual address space
  on the amd64 architecture.  The amd64 architecture requires kernel code and
  global variables to reside in the highest 2GB of the 64-bit virtual address
  space.  Thus, the memory allocated during bootstrap, before the call to
  kmem_init(), starts at KERNBASE, which is not necessarily the same as
  VM_MIN_KERNEL_ADDRESS on amd64.
