Considerations:
  - I can add CONFIG_MONTECITO if necessary. But it will be confusing, I think.

What about this trick below?

identify_cpu() finds out the "c->family".
If any of the CPUs has c->family==32 (and the future versions...) then
set a global flag. And:

static inline void sync_icache_dcache(pte_t pte) {
       if (pte_exec(pte) && global_flag)
               __sync_icache_dcache(pte);
}

Thanks,
