   5 * Everybody gets this wrong and has to stick with it for all
   6 * eternity. Hopefully, this version gets used by new architectures
   7 * so they don't fall into the same traps.
   8 *
   9 * stat64 is copied from powerpc64, with explicit padding added.
  10 * stat is the same structure layout on 64-bit, without the 'long long'
  11 * types.
  12 *
  13 * By convention, 64 bit architectures use the stat interface, while
  14 * 32 bit architectures use the stat64 interface. Note that we don't
  15 * provide an __old_kernel_stat here, which new architecture should
  16 * not have to start with.
