[SPARC64]: Refine code sequences to get the cpu id.
On uniprocessor, it's always zero for optimize that. On SMP, the jmpl to the stub kills the return address stack in the cpu branch prediction logic, so expand the code sequence inline and use a code patching section to fix things up. This also always better and explicit register selection, which will be taken advantage of in a future changeset. The hard_smp_processor_id() function is big, so do not inline it. Fix up tests for Jalapeno to also test for Serrano chips too. These tests want "jbus Ultra-IIIi" cases to match, so that is what we should test for. Signed-off-by: David S. Miller <davem@davemloft.net>
