8  * so they don't fall into the same traps.

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.
