Christoph Lameter 30ed1a79f5 this_cpu: Implement X86 optimized this_cpu operations
Basically the existing percpu ops can be used for this_cpu variants that allow
operations also on dynamically allocated percpu data. However, we do not pass a
reference to a percpu variable in. Instead a dynamically or statically
allocated percpu variable is provided.

Preempt, the non preempt and the irqsafe operations generate the same code.
It will always be possible to have the requires per cpu atomicness in a single
RMW instruction with segment override on x86.

64 bit this_cpu operations are not supported on 32 bit.
