Do these new macros really buy anything over just writing LL in the
few places that 64-bit constants are used?
It gives you macros that matches the s64/u64 et al definitions are,
thus avoiding another class of spurious warnings.
GCC doesn't warn for implicit narrowing that doesn't change value.
The printk() example is a read herring IMHO, since variable arguments
functions are "very speshul" anyway, and require explicit casts in
many cases.
