   7  * current 8MB value just means that there will be a 8MB "hole" after the
   8  * physical memory until the kernel virtual memory starts.  That means that
   9  * any out-of-bounds memory accesses will hopefully be caught.
  10  * The vmalloc() routines leaves a hole of 4kB between each vmalloced
  11  * area for the same reason. ;)
