* The kernel used to define 64-bit types on 64-bit systems on a per-arch
* basis. Some architectures would use unsigned long and others would use
* unsigned long long. These types were exported as part of the
* kernel-userspace ABI and now must be maintained forever. This matches
* what the kernel exports for each architecture so we don't need to cast
* every printing of __u64 or __s64 to stdint types.
* The exception is Android, where for MIPS64 unsigned long long is used.
