Alex, can you please collect all patches into a single patchset? Please split it such that, usage changes are per-system so that they can be routed through respective subsystems (x86 or net) and updates to percpu proper which can be applied after other changes have been applied. It would probably be best to route these patches separately rather than all through percpu as it touches a lot of different places and is likely to cause conflicts. I *think* the best way would be, * Submit per-subsystem patches and get them merged to subsystem trees. * (Optional) Apply a patch to mark unused interface deprecated in percpu tree, so that new usages in linux-next can be detected. * Towards the end of the next merge window, merge a patch to actually kill the old interface.
