x86: Replace uses of current_cpu_data with this_cpu ops
Replace all uses of current_cpu_data with this_cpu operations on the per cpu structure cpu_info. The scala accesses are replaced with the matching this_cpu ops which results in smaller and more efficient code. In the long run, it might be a good idea to remove cpu_data() macro too and use per_cpu macro directly. tj: updated description Cc: Yinghai Lu <yinghai@kernel.org> Cc: Ingo Molnar <mingo@elte.hu> Acked-by: H.
