   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.
