Alternatively, we could just remove the remaining instances in the kernel -
cputime_t is the only borderline reasonable one there; xfs ones should be
__bitwise and so should zd_addr_t thing (with cpu_to_le16() moved from
uses of those suckers to macro definitions). Hell knows - I suspect that
cputime_t also might've been turned into __bitwise u64, but I hadn't checked
if we ever do plain arithmetics on those...
