x86: extend percpu ops to 64 bit
* x86 percpu ops now will work on 64 bit too, so add the missing 8 byte cases.
* Add a few atomic ops that will be useful in the future:
x86_xchg_percpu()
x86_cmpxchg_percpu().
x86_inc_percpu() - Increment by one can generate more efficient
x86_dec_percpu() instructions and inc/dec will be supported by
cpu ops later.
* Use per_cpu_var() instead of per_cpu__##xxx.
