 * physical memory until the kernel virtual memory starts.  That means that
 * any out-of-bounds memory accesses will hopefully be caught.
 * The vmalloc() routines leaves a hole of 4kB between each vmalloced
 * area for the same reason. ;)

 * VMALLOC_START
 * VMALLOC_END
 *      Virtual addresses bounding the vmalloc() area.  There must not be
 *      any static mappings in this area; vmalloc will overwrite them.
 *      The addresses must also be in the kernel segment (see above).
 *      Normally, the vmalloc() area starts VMALLOC_OFFSET bytes above the
 *      last virtual RAM address (found using variable high_memory).
 *
 * VMALLOC_OFFSET
 *      Offset normally incorporated into VMALLOC_START to provide a hole
 *      between virtual RAM and the vmalloc area.  We do this to allow
 *      out of bounds memory accesses (eg, something writing off the end
 *      of the mapped memory map) to be caught.  Normally set to 8MB.
