Looking at this from a kernel's point of view, it looks like there

have them all define 64-bit ints as long long a few years back.

Think printk() too.  Do you use "%lu", "%Lu" or "%llu"?  It's a lot easier if
__u64 is consistently unsigned long long - then it's always "%llu".

The problem with defining it as "unsigned long" on some platforms and
"unsigned long long" on others is that you're guaranteed warnings on one arch
or another.
