No its not pointless churn. We actually eliminate all the pda operations and use the per_cpu operations both on 32 and 64 bit. That is unification.

We would be glad if you could contribute the patches to get rid of the pda.xxx references. I do not think that either Mike or I have the 32 bit expertise needed to do that step. We went as far as we could. The patches are touching all the points of interest so locating the lines to fix should be easy.
