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