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

7
 * eternity. Hopefully, this version gets used by new architectures

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.
