  23  * Just any arbitrary offset to the start of the vmalloc VM area: the
  24  * current 8MB value just means that there will be a 8MB "hole" after the
  25  * physical memory until the kernel virtual memory starts.  That means that
  26  * any out-of-bounds memory accesses will hopefully be caught.
  27  * The vmalloc() routines leaves a hole of 4kB between each vmalloced
  28  * area for the same reason. ;)
