sparc32: move smp ipi to method ops
I ended up renaming set_cpu_int to send_ipi to be consistent all way around. send_ipi was moved to the *_smp.c files so we could call the relevant method direct, without any _ops indirection. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
