0006  * Everybody gets this wrong and has to stick with it for all
0007  * eternity. Hopefully, this version gets used by new architectures
0008  * so they don't fall into the same traps.
0009  *
0010  * stat64 is copied from powerpc64, with explicit padding added.
0011  * stat is the same structure layout on 64-bit, without the 'long long'
0012  * types.
0013  *
0014  * By convention, 64 bit architectures use the stat interface, while
0015  * 32 bit architectures use the stat64 interface. Note that we don't
0016  * provide an __old_kernel_stat here, which new architecture should
0017  * not have to start with.
