Pull perf/urgent fix from Arnaldo Carvalho de Melo:

 - Accept zero as the kernel base address, to resolve symbols on
   architectures that don't partition the virtual address space in
   kernel/user, S/390, is one of such architectures and was where
   this problem was noticed. (Arnaldo Carvalho de Melo)
