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. ;)
