Casts are considered harmful, because they bypass type checking, but how do you print a u64 value? You cast it to "unsigned long long" like this:
printk("%llu\n", (unsigned long long)foo);
Well, this is silly and ugly. As x86-64 has shown, even a 64-bit port can use "long long" for 64-bit values. This patch changes all other 64-bit ports. It now becomes possible to avoid adding new casts all over the place; existing ones may be removed if so desired.
