this is fine.

hm, i dont really like this one - it just adds a special case on an
arch. Why is __u64 unsigned long on powerpc and not unsigned long
long? I thought the whole mess with u64 was fixed there recently and
powerpc too now uses include/asm-generic/int-ll64.h ?
ah, it does this:
/*
* This is here because we used to use l64 for 64bit powerpc
* and we don't want to impact user mode with our change to ll64
* in the kernel.
*/
#if defined(__powerpc64__) && !defined(__KERNEL__)
# include <asm-generic/int-l64.h>
#else
# include <asm-generic/int-ll64.h>
#endif
That's crappy really.
