  12  * Just any arbitrary offset to the start of the vmalloc VM area: the
  13  * current 8MB value just means that there will be a 8MB "hole" after
  14  * the physical memory until the kernel virtual memory starts.  That
  15  * means that any out-of-bounds memory accesses will hopefully be
  16  * caught.  The vmalloc() routines leaves a hole of 4kB (one page)
  17  * between each vmalloced area for the same reason. ;)
