   6  * Everybody gets this wrong and has to stick with it for all

   8  * so they don't fall into the same traps.
   9  *
  10  * stat64 is copied from powerpc64, with explicit padding added.
  11  * stat is the same structure layout on 64-bit, without the 'long long'
  12  * types.
  13  *
  14  * By convention, 64 bit architectures use the stat interface, while
  15  * 32 bit architectures use the stat64 interface. Note that we don't
  16  * provide an __old_kernel_stat here, which new architecture should
  17  * not have to start with.
