[SPARC64]: Sun4v cross-call sending support.
Technically the hypervisor call supports sending in a list of all cpus to get the cross-call, but I only pass in one cpu at a time for now. The multi-cpu support is there, just ifdef'd out so it's easy to enable or delete it later. Signed-off-by: David S. Miller <davem@davemloft.net>
