It changes the bootstrap semantics. The requirement was so far that slab
initialization must be complete before slab operations can be used.

This patchset allows such use before bootstrap on a node is complete and
also allows the running of cache reaper before bootstrap is done.

I have a bad feeling that this could be the result of Pekka's changes to
the bootstrap.
