Yes, but wouldn't it be much better to avoid code like the following,

#ifdef CONFIG_64BIT // or maybe CONFIG_X86_64?

#define fast_u32 u32

How about using just unsigned long instead?
unsigned long happens to coincide with uint_fast32_t for x86 and x86-64,
but there's no guarantee that it will on other architectures. And, at
least in theory, long may even provide less than 32 bits.
