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.
