It seems like an odd interface. > Because on PPC, you usually run PPC32 userspace code on a PPC64 kernel. Unlike with x86, there's no real benefit in using 64 bit userspace. So thanks to the nature of big endianness, that breaks our set_bit helpers, because they assume you're using "long" data types for the bits. While that's no real issue on little endian, since the next int is just the high part of a u64, it messes everything up on ppc. For more details, please just look in the archives on my patches to make it little endian.
