use the new percpu interface for shared data

Currently most of the per cpu data, which is accessed by different cpus,
has a ____cacheline_aligned_in_smp attribute.  Move all this data to the
new per cpu shared data section: .data.percpu.shared_aligned.

This will seperate the percpu data which is referenced frequently by other
cpus from the local only percpu data.
