History
Christoph Lameter e800879d50 this_cpu: Use this_cpu operations in RCU 
RCU does not do dynamic allocations but it increments per cpu variables
a lot. These instructions results in a move to a register and then back
to memory. This patch will make it use the inc/dec instructions on x86
that do not need a register.
