x86 CPU specific code is currently implemented in different ways for
64 and 32 bit. While there are almost no CPU specific files for 64

already an idea about whether to use kernel/cpu also for 64 bit?
It is also used for 64bit for years.
Yes, but almost all files in arch/x86/kernel/cpu/ depend on
CONFIG_X86_32.
Here is an example for similiar implementations:
arch/x86/kernel/cpu/amd.c:static void __cpuinit init_amd(struct cpuinfo_x86 *c)
arch/x86/kernel/setup_64.c:static void __cpuinit init_amd(struct cpuinfo_x86 *c)
The question is, will there be a CPU specific file such as amd.c?
That's my current intent, as I consider the 32-bit code cleaner even
though Andi disagrees. That doesn't mean it's good enough as-is, of
course, but I would like to maintain things reasonably well separated out.
